Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a coated three-dimensional image sample plate in which an accurate three-dimensional image sample corresponding to an original image of a base material having a design property is coated.

[0002]

2. Description of the Related Art In recent years, a design-coated plate having a surface coated with a design has been widely used. As such a design coated plate, for example, a wall surface material for construction and the like, on which the coating of various patterns having a design property is applied, is mentioned. Such a design coated plate is generally manufactured by the following procedure. To be done. That is, first, a base material having an uneven surface (for example, gypsum board, metal plate, ceramic building material, etc.) is prepared.
Then, the base material is painted to express a predetermined pattern devised by a designer or the like (for example, a pattern having a brick appearance). In addition, in order to give a more realistic feeling, such coating is often applied (applied repeatedly) a plurality of times.

By the way, in order to commercially manufacture such a design coated plate, a sample of the base material (hereinafter referred to as a "stereoscopic image sample") or a sample of the designed coated plate (hereinafter referred to as "Coating stereoscopic image sample board") is produced, and based on the stereoscopic image sample or the coating stereoscopic image sample board, the layout balance of the design of the design coating board to be manufactured, suitability of colors, etc. are grasped, and the design is calculated. It is usual to predict and evaluate the effectiveness (commerciality) of a coated plate as a product. Such a stereoscopic image sample or a painted stereoscopic image sample plate has been conventionally manufactured by the following procedure.

That is, as shown in FIG. 2, a natural material such as natural stone or natural wood is used as a sample, or an original image of a design-coated plate (for example, CR
The image displayed on the T display screen or the image printed by a color printer) is visually observed (step T1), and a three-dimensional model corresponding to the original image is clay-crafted (clay-shaped), or A wood pattern is produced by carving wood (step T2).

Next, a liquid or flowable matrix material (for example, silicon) is poured onto the mold surface (design surface) of the model, and the matrix material is solidified and then removed from the model. A mother die having a die surface having a shape in which irregularities are reversed from that of the die surface is manufactured (step T3). Subsequently, liquid or mud-shaped gypsum is poured into the mold surface of the mother mold and left until the gypsum solidifies (step T4). Then, the solidified gypsum is removed from the mother mold, and the gypsum mold having the same shape as the model,
That is, a stereoscopic image sample that stereoscopically represents the base material is obtained (step T5). After that, after polishing the three-dimensional image sample (gypsum mold) (step T6), the mold surface (design forming surface) of this three-dimensional image sample is painted or colored to obtain a painted three-dimensional image sample board (step T7). .

[0006]

However, in the conventional method for producing a stereoscopic image sample or a painted stereoscopic image sample plate as shown in FIG. 2, manual work such as clay work or wood engraving based on visual observation is required. Due to the central relationship, there is a problem that a great deal of labor or skill is required to manufacture the three-dimensional image sample or the painted three-dimensional image sample plate, and the manufacturing cost thereof is very high.

By the way, the base material or building material having an uneven surface, which is the material of the design coated plate as described above, is made of a material (ceramic material) which can be plastically deformed in a semi-solid state, such as concrete, in a predetermined raw material. In many cases, it is mass-produced by a method of press-molding with a mold (female mold) having a mold surface corresponding to the inverted concavo-convex material of the base material, and then completely solidifying the plastically deformable material. That is, such a substrate or building material is a duplicate stereoscopic image or a duplicate of the original substrate.
In this case, the mold is generally manufactured by the following procedure.

[0008] That is, first, an actual material (for example, natural stone, brick, etc.), that is, an original base material provided with an irregular surface of a predetermined shape having a design property (hereinafter referred to as "male irregular surface") is prepared, After the silicon resin is pressure-bonded to the male concave-convex surface of the actual material, the silicon resin is solidified. next,
A mold (female mold) in which the solidified silicone resin is released from the actual material, and the concave and convex surface of the male concave and convex surface is reversed (hereinafter referred to as “female concave and convex surface”) ) Get. Then, after pouring a heat resistant material such as gypsum onto the mold surface of the mold made of this silicone resin, the heat resistant material is solidified. Next, the solidified heat-resistant material is released from the mold to obtain a heat-resistant mold having a male concave-convex surface as a mold surface. Furthermore, after pouring molten iron into the heat-resistant mold surface, the iron is solidified.
After that, the solidified iron is released from the heat-resistant mold to obtain a mold having the female mold irregular surface as the mold surface.

In the conventional method of manufacturing a mold or die as described above, in order to manufacture a base material or a building material having a new shape corresponding to a new original base material, first, an actual material must be manufactured. However, the production of the actual material requires a great deal of labor or skill to produce the actual material, because the manual operation such as cutting of natural stone, clay work, or engraving of wood is central to the production of the actual material. Therefore, there is a problem that the manufacturing cost of the mold or the mold becomes high, and the manufacturing cost of the base material or the building material (reproduction stereoscopic image) becomes high.

The present invention has been made to solve the above-mentioned conventional problems, and is a stereoscopic image sample that stereoscopically expresses a base material or the like, or a painted stereoscopic image that stereoscopically expresses a design coating plate or the like. The sample board, without requiring special skill
It is an object to be solved to provide a simple means that can be manufactured quickly and at low cost. Further, it is possible to easily and at low cost to form a mold or a mold for producing a base material or a building material (a duplicate stereoscopic image) having a shape corresponding to the original base material by press molding, and thus, the base material or It is an object to be solved to provide a means capable of reducing the manufacturing cost of a building material (a duplicate stereoscopic image).

In the method of creating the stereoscopic image sample,
The photosensitive plate material is irradiated with ultraviolet rays or the like with an irradiation characteristic (light pattern) corresponding to the original image of the base material, and then the photosensitive plate material is subjected to a development process in a simple process. It is possible to manufacture a stereoscopic image sample having an uneven shape that accurately corresponds to the original image. Then, by applying an appropriate coating to the three-dimensional image sample, the coated three-dimensional image sample plate can be easily manufactured. Therefore, the process is greatly simplified as compared with the conventional method for producing a stereoscopic image sample or a painted stereoscopic image sample plate, so that an accurate stereoscopic image sample or a painted stereoscopic image sample plate can be obtained without special skill. It can be manufactured easily and quickly. In addition, the manufacturing cost can be significantly reduced.

In the above-mentioned method for producing a stereoscopic image sample,
Irradiation with ultraviolet rays or the like is performed based on digital image data corresponding to an original image of a base material having a design property, and a three-dimensional image sample having an uneven shape corresponding to the base material on the surface is created. Is preferred. By doing so, it is possible to directly create a stereoscopic image sample based on the digital image data of the design pattern of the design coating plate created by the designer, etc. It is possible to easily and quickly produce a simple stereoscopic image sample.

Further, in the above-described method for producing a stereoscopic image sample, gradation reproduction processing is performed on digital image data, and ultraviolet rays or the like is irradiated based on the digital image data subjected to the gradation reproduction processing. Is preferred. here,
As the gradation reproduction processing method, for example, an error diffusion dither method,
Examples include a density pattern method, a halftone dot method, and a density gradation compression division method. Note that it is preferable to perform gradation correction processing (gradation correction processing) on the digital image data before or after the gradation reproduction processing.

In general, when the photosensitive plate material is irradiated with ultraviolet rays or the like based on digital image data which is not subjected to gradation reproduction processing, the boundary between the portions which are exposed to ultraviolet rays and the portions which are not exposed is relatively clear. The unevenness formed on the photosensitive plate material becomes a very sharp shape. For example, the corners of the ends of the protrusions or recesses have a right-angled shape, and the boundary between the protrusions and recesses has a cliff-like shape. Therefore, it is extremely difficult to represent a three-dimensional shape with rounded corners or a three-dimensional shape in which convex portions and concave portions gently change. Therefore, it is virtually impossible to manufacture a stereoscopic image sample that accurately represents a base material having an uneven shape in which the corners are rounded or gently undulated.

However, if the ultraviolet ray or the like is irradiated on the basis of the digital image data which has been subjected to the tone reproduction processing as described above, the boundary between the portion which is exposed to the ultraviolet ray and the portion which is not exposed becomes unclear, so that in such an area. , The photosensitive plate material is not completely cured. Therefore, when the photosensitive plate material is subjected to development processing, the material is appropriately removed (residual) in this portion according to the amount of light received, and the corners are It is possible to obtain a rounded three-dimensional shape or a three-dimensional shape in which the convex portion and the concave portion gently change. Therefore, the corners are rounded,
Alternatively, it is possible to manufacture a stereoscopic image sample that accurately expresses a base material having an uneven shape that gently undulates.

In the above-mentioned method for producing a stereoscopic image sample,
Create a second original drawing corresponding to the original image having design characteristics, place (paste) the second original drawing on the surface of the photosensitive plate material, and irradiate the surface of the photosensitive plate material with ultraviolet rays or the like from the second original drawing side. Preferably. Then, it is more preferable to create the second original drawing based on the digital image data corresponding to the original image of the base material having the design property. In this case, it is preferable to perform gradation reproduction processing on the digital image data and create the second original drawing based on the digital image data subjected to the gradation reproduction processing. Here, as the gradation reproduction processing method,
Examples thereof include an error diffusion dither method, a density pattern method, a halftone dot method, and a density gradation compression division method. Note that it is preferable to perform gradation correction processing (gradation correction processing) on the digital image data before or after the gradation reproduction processing.

The second original drawing is 300 to 500.
a material that absorbs light with a wavelength of nm, such as a silver salt film,
A non-silver salt film or the like can be used. in this way,
If the second original image is used, it is possible to precisely correspond to the original image of the base material or the like on the surface of the photosensitive plate material simply by irradiating the photosensitive plate material with uniform ultraviolet rays from the second original image side. Or, it can be irradiated with ultraviolet rays or the like depending on the irradiation characteristics. Therefore,
The mechanism for irradiating the photosensitive plate material with ultraviolet rays is simplified.

In the method of creating the stereoscopic image sample,
It is preferable to arrange the second original so that the image film surface (emulsion-attached surface) thereof does not come into direct contact with the uneven surface of the photosensitive plate material, and irradiate the photosensitive plate material with ultraviolet rays or the like from the side of the second original image. . Here, as a specific method for preventing the image film surface of the second original image from directly contacting the unevenness forming surface of the photosensitive plate material, for example, the surface of the second original image on the surface on which the image film is not formed is described. A method of arranging so that (the surface on the side opposite to the image film surface) contacts the surface of the photosensitive plate material, an air layer is provided between the second original image and the photosensitive plate material, or a transparent intermediate film. And a method of interposing a mesh-shaped material, a method of using these in combination, and the like.

In this way, part of the ultraviolet rays or the like is transparent to the main body portion (transparent) or transparent of the second original image before the ultraviolet rays reach the photosensitive plate material from the image film surface of the second original image. Is scattered by a transparent intermediate film, and this scattered light
A moderate amount of photocuring is caused in a portion around a portion that should be exposed to ultraviolet rays (hereinafter, referred to as "ultraviolet ray irradiation portion") (hereinafter, this portion is referred to as "partial irradiation portion").
Thus, since a partial irradiation portion is formed around the ultraviolet irradiation portion where almost all photo-curing occurs, that is, a portion which should be a convex portion, when the photosensitive plate material is subsequently subjected to a developing treatment, the convex portion is not formed. A part where the material remains moderately around is generated, whereby a three-dimensional shape with rounded corners or a three-dimensional shape in which convex portions and concave portions gently change can be obtained. Therefore, it is possible to manufacture a three-dimensional image sample that accurately expresses a base material having an uneven shape in which the corners are rounded or gently undulated.

Further, in the method for producing the three-dimensional image sample, a photosensitive plate material having a transparent base film attached to the back surface thereof is used, and (a) the second original image is arranged on the surface of the base film, The back surface of the photosensitive plate material is irradiated with ultraviolet rays or the like from the second original drawing side through the base film,
(B) Thereafter, the photosensitive plate material may be subjected to a development treatment from the front side of the photosensitive plate material. In this case, for example, the second
A method of arranging the original so that the surface on which the image film is not formed contacts the surface of the base film, a method of interposing a transparent intermediate film between the second original and the base film, or these The second original drawing may be arranged such that the image film surface thereof does not come into direct contact with the surface of the base film by a method or the like in combination with.

According to such a sample preparation method (hereinafter, referred to as "back surface irradiation method") in which ultraviolet rays or the like are irradiated from the back surface of the photosensitive plate material, and development processing is performed from the front surface. For example, the height of the convex portion changes according to the density (light absorption rate) of the image film surface of the second original image. That is, if the light absorptivity of the image film surface is 0% (completely transparent), complete photo-curing occurs in this portion, and this portion becomes a complete convex portion. On the contrary, if the light absorptance of the image film surface is 100% (black), photocuring does not occur at all in this portion, and this portion becomes a complete recess. If the light absorptivity of the image film surface is, for example, 60% (intermediate density), only 40% of the ultraviolet rays and the like hit this portion compared to the completely transparent portion. Photocuring occurs only in about 40% of the surface, and does not occur in 60% of the front side. Here, if development processing is applied from the front surface, 60% of the material is removed,
Therefore, a convex portion whose height is about 40% lower than that of the complete convex portion is formed in this portion. Thus, if the light absorptance of the image film surface is preferably changed between 0 and 100%, it is possible to form a convex portion having an arbitrary height. Therefore, it is possible to manufacture a stereoscopic image sample that accurately expresses the shape of a base material having a complicated concavo-convex shape in which the heights of the convex portions are different. Here, if the second original image is further arranged so that the image film surface thereof does not come into direct contact with the base film, as described above, the base material having the uneven shape in which the corners are rounded or gently undulated accurately is obtained. Since it can be expressed, it is possible to manufacture a stereoscopic image sample that more accurately expresses a base material having a complicated uneven shape.

According to the second aspect of the present invention, the original image or the base material having a design property, which is created by using the method for creating a stereoscopic image sample described in any one of the above, is three-dimensionally formed. A stereoscopic image sample for representation is provided. It is preferable that a (hard) lightweight backing material (for example, a foamed material such as urethane resin, polyethylene resin, acrylic resin, or styrene resin) is attached to the back surface of the three-dimensional image sample. By doing so, the strength of the stereoscopic image sample can be significantly increased without increasing the weight. Thus,
It is possible to obtain a highly durable three-dimensional image sample that accurately represents the shape of the base material.

According to a third aspect of the present invention, a painted three-dimensional image sample board in which one surface or a multi-colored coating is applied with a paint on the front surface of the three-dimensional image sample, or There is provided a coated three-dimensional image sample board, which is further coated with a paint having a one-color or multi-color design property using a paint. Thus, a painted three-dimensional image sample board that accurately expresses the color tone, shape, etc. of the design painted board can be obtained.

According to the fourth aspect of the present invention, (a) an original image having a design property is provided on the surface of a photosensitive plate material containing the photocurable composition with at least one of ultraviolet rays and laser rays. (B) Next, the photosensitive plate material is subjected to a developing treatment to irradiate it with an irradiation characteristic corresponding to the reversal image of FIG. Are removed to form a concave portion and the photo-cured portion is left to form a convex portion to form an uneven surface corresponding to an inverted image of the original image. (C) The uneven surface is released with a release treatment agent. Provided is a method for creating a stereoscopic image mold, which comprises performing a mold process to create a mold having a mold surface corresponding to an inverted image of an original image. The characteristics of the photosensitive plate material, the ultraviolet rays, the laser beam, and the like used in the method for producing the stereoscopic image frame are the same as those in the method for producing the stereoscopic image sample.

In the method of creating the three-dimensional image form,
The photosensitive plate material is irradiated with ultraviolet rays or the like with an irradiation characteristic (light pattern) corresponding to an inverted image of an image of a desired original substrate (for example, natural stone), and then the photosensitive plate material is subjected to development processing. It is possible to manufacture a stereoscopic image mold having a concave and convex shape as a mold surface, which accurately corresponds to the concave and convex inverted product of the original substrate, by a simple process. Then, using this stereoscopic image form, it is possible to manufacture a press-molding die of a material that can be plastically deformed (ceramic material) by the same method as the conventional method. It is possible to easily create a duplicate stereoscopic image (a duplicate) of the original base material by using a material or the like capable of performing the above. That is, it is possible to easily and at low cost to form a mold or a mold for making a base material or a building material that is a duplicate of an original base material having an uneven surface having a design property,
Consequently, it is possible to reduce the manufacturing cost of the base material or the building material (reproduction stereoscopic image).

In the method of creating the stereoscopic image form,
Irradiation of ultraviolet rays, etc. is performed based on digital image data corresponding to an inverted image of the image of the original base material having a design property,
It is preferable to prepare a mold frame having a concavo-convex shape in which concavities and convexities are reversed from the original base material. By doing this, digital image data of a large number of base material patterns or design patterns created by designers (for example, 1 million kinds of two-dimensional infinite arbitrary designs) without producing actual materials by cutting natural stone or the like. Based on the data), the stereoscopic image form can be directly and easily created quickly.

In the method of creating the stereoscopic image form,
It is preferable to perform gradation reproduction processing on the digital image data and irradiate ultraviolet rays or the like based on the digital image data subjected to the gradation reproduction processing. Here, examples of the gradation reproduction processing method include an error diffusion dither method, a density pattern method, a halftone dot method, and a density gradation compression division method. Note that it is preferable to perform gradation correction processing (gradation correction processing) on the digital image data before or after the gradation reproduction processing. In the above-described method for creating a stereoscopic image frame, the operation and effect of performing gradation reproduction processing or gradation correction processing on digital image data are the same as in the case of the above-described method for creating a stereoscopic image sample.

In the above method of creating a stereoscopic image form,
Create a second original drawing corresponding to an inverted image of the original image having design characteristics, and arrange (paste) the second original drawing on the surface of the photosensitive plate material.
However, it is preferable to irradiate the surface of the photosensitive plate material with ultraviolet rays or the like from the second original drawing side. Further, it is more preferable to create the second original drawing based on digital image data corresponding to an inverted image of the image of the original base material having the design property. In this case, it is preferable to perform gradation reproduction processing on the digital image data and create the second original drawing based on the digital image data subjected to the gradation reproduction processing. Here, examples of the gradation reproduction processing method include an error diffusion dither method, a density pattern method, a halftone dot method, and a density gradation compression division method. Note that it is preferable to perform gradation correction processing (gradation correction processing) on the digital image data before or after the gradation reproduction processing. The characteristics such as the material of the second original drawing used for creating the stereoscopic image form are the same as those for creating the stereoscopic image sample. In the method of creating a stereoscopic image form, the operation / effect when the second original image is used or the operation / effect when the gradation reproduction processing or the gradation correction processing is applied to the digital image data is This is similar to the case of the above-described method of creating a stereoscopic image sample.

In the above method of creating a stereoscopic image form,
It is preferable to arrange the second original so that the image film surface (emulsion-attached surface) thereof does not come into direct contact with the uneven surface of the photosensitive plate material, and irradiate the photosensitive plate material with ultraviolet rays or the like from the side of the second original image. . Here, as a specific method for preventing the image film surface of the second original image from directly contacting the unevenness forming surface of the photosensitive plate material, for example, the surface of the second original image on the surface on which the image film is not formed is described. A method of arranging so that (the surface on the side opposite to the image film surface) contacts the surface of the photosensitive plate material, an air layer is provided between the second original image and the photosensitive plate material, or a transparent intermediate film. And a method of interposing a mesh-shaped material, a method of using these in combination, and the like. In the above method for producing a stereoscopic image frame, the operation and effect when the second original image is arranged so that the image film surface thereof does not come into direct contact with the unevenness forming surface of the photosensitive plate material is the stereoscopic image described above. This is the same as the case of creating the sample.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be specifically described below. First, an outline of a method for producing a stereoscopic image sample or a painted stereoscopic image sample plate according to the present invention will be described.
FIG. 1 is a flowchart showing a manufacturing process of a three-dimensional image sample or a coated three-dimensional image sample plate that accurately expresses the three-dimensional shape, color tone, etc. of a base material or a design coated plate having a design property. As shown in FIG. 1, in this manufacturing process, first, digital image data corresponding to a simulation image of a design coated plate having a design property is prepared (step S1). In addition, such digital image data is
For example, image data of a design pattern image (for example, a wood grain pattern, a brick pattern, an abstract pattern, a geometric pattern, etc.) having a design property created by a designer or a user using a computer graphic system, and a base material (for example, a bone). It is created by a method of combining image data of a base material image representing a material, a building, etc.) and image data representing a state in which a pattern image is painted on the surface of the base material in a pseudo manner.

Next, gradation reproduction processing is performed on the digital image data to create gradation reproduction image data that simulates the original image (step S2). here,
As a gradation reproduction method, as will be specifically described later,
A dither method such as an error diffusion dither method (average error minimum dither method), a density pattern method, a halftone dot method (AM screen method), a density gradation compression division method and the like are used. Note that continuous tone image data may be used.

Subsequently, the gradation reproduction image data is subjected to gradation correction processing (gradation tone correction processing) with a predetermined correction characteristic (step S3). In the process of manufacturing the three-dimensional image sample or the coated three-dimensional image sample plate, a plate-making film (second original drawing) is attached to the surface of the photosensitive plate material, and the photosensitive plate material is inserted through the plate-making film, as will be described later. UV irradiation of the plate-making film to cure the part corresponding to the transparent part of the plate-making film by photo-curing, while leaving the part corresponding to the colored part of the plate-making film soft, after which development processing such as scraping with a brush is performed. Thus, the soft portion is removed to form an uneven shape corresponding to the image on the plate-making film.

In this case, the image on the plate-making film and the uneven shape formed on the photosensitive plate material are deviated from each other depending on the exposure condition or the developing condition material. Therefore, the gradation correction processing is performed on the gradation reproduction image data with a correction characteristic that reduces the deviation. The gradation correction process is performed by changing the screen ruling, the halftone dot size (halftone dot%), the ID, the dot density, and the like. Note that the gradation correction processing may be performed on the digital image data before the gradation reproduction processing.

Then, based on the gradation reproduction image data which has been subjected to the gradation correction processing, a plate-making film (negative film or positive film) having an image film surface (emulsion surface) corresponding thereto is prepared (step). S4). This plate-making film is automatically prepared using, for example, a commercially available imagesetter or the like. The plate-making film is prepared using a silver salt film or a non-silver salt film. And
A three-dimensional image sample having a concavo-convex shape corresponding to an image (that is, a gradation reproduction image) displayed on the plate-making film, that is, a concavo-convex shape corresponding to a base material is produced using the plate-making film (step S5). That is, flexible plate making is performed. The specific plate making method of this flexographic plate making is as described below.

Next, a lightweight backing is attached to the back surface of the three-dimensional image sample (step S6). Here, as the material of the lightweight backing material, for example, a urethane resin, polyethylene resin, acrylic resin, styrene resin, or other relatively hard resin foam is used in order to reduce the weight of the three-dimensional image sample and increase its strength. Is preferred. Thus, a highly durable stereoscopic image sample that accurately represents the shape of the substrate can be obtained.

Thereafter, the surface of the three-dimensional image sample is painted with a desired paint, and if necessary, the paint or coloring having a predetermined design property is applied with the desired paint. Image sample is completed (step S
7). Thus, a painted stereoscopic image sample board that accurately expresses the color tone, shape, etc. of the designed painted board intended by the designer or the like can be obtained.

Hereinafter, the processing method of the tone reproduction processing in step S2 will be described more specifically. As the gradation reproduction method, a dither method such as an error diffusion dither method (mean error minimum dither method), a density pattern method, a halftone dot method (AM screen method), a density gradation division method (continuous density compression method), etc. are used. To be Among these gradation reproduction methods, the dither method is a gradation reproduction method in which each pixel of the grayscale image is binarized by dividing it into white or black with substantially different thresholds. Random dither method, systematic dither method, error diffusion dither method (mean error minimum dither method), mean value limited dither method, and the like. Among these dither methods, the error diffusion dither method has an advantage of preventing formation of false contours in the gradation reproduction image.

In the density pattern method, each pixel of the original image represented by halftone is composed of, for example, n × n (n is a natural number) dot areas (points), and each dot area is white or black. It is intended to represent halftone by changing the ratio of the number of white dot areas (white dots) and black dot areas (black dots) in each pixel. It should be noted that this density pattern method can be said to be a gradation reproduction method suitable for obtaining an image having a good halftone while sacrificing the image resolution to some extent.

In the halftone dot method (AM screen method), a pixel of a predetermined size is assigned as a display pixel to the density level of one pixel of the grayscale original image, and is proportional to the density level of the grayscale original image. This is a method of creating a pseudo halftone by increasing the black occupied area in the display pixel, and is a gradation reproduction method mainly used in the technical field of printing.

Density gradation compression division method (continuous density compression method)
Is a gradation reproduction method in which a continuous gradation image is divided into several kinds of density gradation areas to express a gradation (halftone) or a color gradation (multicolor). Here, each density gradation area is a solid plate (it is possible to further perform a binarization process such as a full-color solid halftone dot meshing process with a halftone dot if necessary). Therefore, unlike the halftone dot method, etc. Since halftone dot decomposition is not performed, there is an advantage that the gradation reproducibility is high especially in the vicinity of highlights.

FIG. 3A schematically shows a grayscale representation by the error diffusion dither method. It should be noted that in FIG. 3A, the left side diagram shows a continuous tone original image, and the right side diagram shows a tone reproduced image obtained by subjecting the original image to tone reproduction processing by the error diffusion dither method. There is. Further, FIG. 5 shows a gradation reproduction image obtained by performing gradation reproduction processing of the continuous gradation pattern image (original image) shown in FIG. 4 by the error diffusion dither method. Here, the pattern image shown in FIG. 4 is expressed with 256 shades of gray, and the gradation reproduction image shown in FIG. 5 is expressed with two monochrome gradations of 100 dots / inch. As is clear from FIG. 5, in the tone reproduction image obtained by the tone reproduction processing by the error diffusion dither method, no false contour is formed and a good halftone with good image quality is obtained.

In FIG. 3 (c), the diagram on the left side shows a pattern image, and the diagram on the right side shows an enlarged gradation reproduction image obtained by gradation reproduction processing of a part of the pattern image by the halftone dot method. ing.

The gradation reproduction image shown in FIG. 7 is expressed in monochrome 2 gradations with a screen ruling of 30 lines / inch. As is clear from FIG. 7, the tone reproduction image obtained by the tone reproduction process by the halftone dot method also has a relatively good halftone.

Further, FIG. 8 shows a gradation reproduction image obtained by gradation reproduction processing of the continuous gradation pattern image shown in FIG. 4 by the density gradation compression division method. As is clear from FIG. 8, a good gradation reproduction image is obtained by the density gradation compression division method.

Hereinafter, the plate making method of the flexographic plate making in step S5 will be described more specifically. As shown in FIG. 9, in this plate making method, first, the photosensitive plate material 1 is prepared. This photosensitive plate material 1 comprises a photosensitive layer 2 and a transparent base film 3 attached to the back surface of the photosensitive layer 2.
(Plastic sheet), a slip layer attached to the front surface of the photosensitive layer 2, and a protective cover layer 4 (plastic sheet). Here, the photosensitive layer 2 is
It contains a polymer binder, a monomer having an ethylenically unsaturated double bond, and a photo-curing initiator, and when it is irradiated with ultraviolet rays or the like, it undergoes photo-curing and cures. It should be noted that the portion that is not irradiated with ultraviolet rays, that is, the portion that is not cured by photocuring is relatively soft, and can be easily scraped in water by rubbing with a brush or the like.

In this flexographic plate making, basically, the plate making film 5 (second original drawing) is attached to the surface of the photosensitive plate material 1 by vacuum adhesion, and then the plate making film 5 is made.
From the side, the photosensitive plate material 1 (photosensitive layer 2) is irradiated with ultraviolet rays or the like (exposure treatment), that is, with an irradiation characteristic corresponding to the image of the plate-making film 5 to cause photo-curing in the light receiving portion of the photosensitive layer 2. Then, the photosensitive layer 2 is subjected to a developing treatment such as scraping with a brush or the like to remove the non-photocured portion to form a concave portion and leave the photocured portion to form a convex portion. Then, a three-dimensional image sample having an uneven shape corresponding to the original image on the surface is created.

As described above, when using the plate-making film 5 prepared based on the digital image data which is not subjected to the gradation reproduction processing, the boundary between the part exposed to ultraviolet rays and the part not exposed is relatively clear. The irregularities formed on the photosensitive plate material 1 (photosensitive layer 2) have a very sharp shape. For example, the corners of the protrusions have a right-angled shape, and the boundary between the protrusions and the recesses has a precipitous cliff shape. For this reason, three-dimensional shapes with rounded corners or convex parts (concave parts)
It is not possible to express a three-dimensional shape in which the shape changes gently from a concave portion to a concave portion. Therefore, it is virtually impossible to manufacture a stereoscopic image sample that accurately represents a base material having an uneven shape in which the corners are rounded or gently undulated.

However, in the plate-making method according to the present invention, since the plate-making film 5 created based on the tone reproduction image data subjected to the tone reproduction processing is used, the portion of the photosensitive layer 2 exposed to the ultraviolet rays or the like is not used. The boundary with the untouched part is not so clear. Therefore, in the boundary region, the photosensitive layer 2 is partially hardened, and therefore, when the developing process is performed, the plate material is appropriately removed (residual) in the boundary region, and the corners are rounded. A three-dimensional image sample having a three-dimensional shape or a three-dimensional shape that gently changes from a convex portion (recess) to a concave portion (convex) can be obtained. Therefore,
It is possible to easily and quickly manufacture a stereoscopic image sample that accurately expresses a base material having an uneven shape in which the corners are rounded or gently undulated.

By the way, various kinds of plate-making forms can be used, and the characteristics of the uneven shape formed on the photosensitive plate material 1 (photosensitive layer 2) also change variously due to the difference in the plate-making forms. . Therefore, by utilizing this, it is possible to manufacture a three-dimensional image sample having a three-dimensional shape with rounded corners or a three-dimensional shape in which a convex portion changes to a concave portion gently. Furthermore, a stereoscopic image sample that accurately expresses the shape of a base material that can form convex portions with different heights and therefore has a complicated uneven shape with different heights of the convex portions is manufactured. be able to.

A method for preferably changing the form of the stereoscopic image sample by changing the plate making form in this manner will be described below. As described above, since the plate-making film according to the present invention uses the plate-making film created by the tone reproduction data, the corners of the three-dimensional image sample are rounded or the boundary between the convex and concave portions is also increased. Although the part has a gentle shape, in the following, in order to clarify the difference in action and effect due to the difference in plate making form, it is assumed that the above-described action and effect due to the gradation reproduction processing do not occur. To do. Therefore, in actuality, the action and effect due to the difference in plate making form described below and the action and effect due to the gradation reproduction processing compete with each other.

Regarding the arrangement form of the plate-making film on the photosensitive plate material 1, the plate-making film is directly arranged on the front surface of the photosensitive layer 2 after removing the protective cover layer 4, and the plate-making film is arranged. Can be arranged on the surface of the base film 3, that is, on the back side surface of the photosensitive plate material 1 (film back side arrangement).
Further, a mode in which the image film surface 6 (emulsion surface) of the plate-making film faces the photosensitive plate material side (arrangement close to the film surface), and the photosensitive plate material 1
Two forms of facing the opposite side (separation of membrane surface)
Two forms can be used. Regarding the contact form between the plate-making film and the photosensitive plate material 1, there are two forms, a form in which they are in direct contact (film direct arrangement) and a form in which a transparent intermediate film is interposed between them (film indirect arrangement form). Forms can be used. In any case, the development process, such as scraping with a brush or the like, is performed on the front surface of the photosensitive plate material 2 after the exposure process is completed.

Therefore, the following eight forms can be used as the plate making form. (1) Film front side / direct arrangement / membrane surface close arrangement form (2) Film front side / direct arrangement / membrane surface separation arrangement form (3) Film front side / indirect arrangement / membrane surface close arrangement form (4) Film front side / indirect arrangement・ Membrane surface separation arrangement form (5) Film backside / direct arrangement ・ Membrane surface close arrangement form (6) Film backside ・ Direct arrangement ・ Membrane surface separation arrangement form (7) Film backside ・ Indirect arrangement ・ Membrane surface close arrangement form (8) ) Film back side / indirect arrangement / separation of film surface arrangement form The plate making forms (1) to (8) may be combined.

Hereinafter, the plate making method in the eight plate making modes (1) to (8) will be specifically described. (1) Film Front Side / Direct Arrangement / Membrane Surface Proximity Arrangement Form As shown in FIG. 10A, in this case, first, the protective cover layer 4 is removed, and then the photosensitive layer 2 exposed to the outside is removed.
The plate-making film 5 is arranged (attached) on the front surface of the so that the image film surface 6 thereof contacts the photosensitive layer 2.
Next, as shown in FIG. 10B, the photosensitive plate material 1 (photosensitive layer 2) is irradiated with ultraviolet rays or the like from the plate-making film 5 side. Here, in a portion of the plate-making film 5 where the image film surface 6 is not formed (that is, a transparent portion), ultraviolet rays and the like pass through the plate-making film 5 and reach the photosensitive layer 2, which is cured by photo-curing and cured. Form part 7. On the other hand, plate making film 5
In the portion where the image film surface 6 is formed (that is, the opaque portion), ultraviolet rays and the like are absorbed by the image film surface 6 and therefore do not reach the photosensitive layer 2, and therefore the portion of the photosensitive layer 2 corresponding thereto. Remains uncured.

Thereafter, as shown in FIG. 10C, the plate-making film 5 is removed, and then the front surface of the photosensitive layer 2 is subjected to a developing treatment such as scraping with a brush. At this time, the uncured portion of the photosensitive layer 2 is removed (scraped), while the cured portion 7 remains as it is. Thus, FIG.
As shown in (d), a stereoscopic image sample M ₁ having an image displayed on the plate-making film 5, that is, an uneven shape corresponding to the shape of the substrate is obtained. According to this plate-making method, the image film surface 6 of the plate-making film 5 adheres to the front surface of the photosensitive layer 2,
Therefore, the ultraviolet rays and the like that have passed through the image film surface forming portion of the plate-making film 5 reach the photosensitive layer 2 without being scattered, so that the cured portion 7 having a shape substantially matching the shape of the image film surface 6 is formed. Therefore, in the stereoscopic image sample M ₁ , the corner C ₁
Has a substantially right-angled shape, and the boundary W ₁ between the convex portion and the concave portion has a substantially cliff-like shape, so that a sharp uneven shape is formed.

(2) Film Front Side / Direct Arrangement / Membrane Surface Separation Arrangement As shown in FIG. 11 (a), in this case, the protective cover layer 4 is first removed, and then the front surface of the photosensitive layer 2 is removed. The plate-making film 5 is arranged (attached) in such a manner that the image film surface 6 thereof faces the direction (outside) opposite to the photosensitive layer 2. Next, as shown in FIG. 11B, the photosensitive plate material 1 (photosensitive layer 2) is irradiated with ultraviolet rays or the like from the plate-making film 5 side. Here, in a portion (transparent portion) of the plate-making film 5 where the image film surface 6 is not formed, ultraviolet rays or the like pass through the plate-making film 5 and reach the photosensitive layer 2 to be cured by photocuring,
The hardening part 7 is formed. On the other hand, in the portion (opaque portion) of the plate-making film 5 on which the image film surface 6 is formed, basically, the ultraviolet rays and the like are absorbed by the image film surface 6 and therefore do not reach the photosensitive layer 2, and therefore the photosensitive layer 2 is not exposed. The corresponding part of layer 2 remains uncured. However, in this case, until the ultraviolet rays or the like that have passed through the image film surface forming portion of the plate-making film 5 pass through the transparent main body of the plate-making film 5 and reach the photosensitive layer 2, a part of the ultraviolet rays or the like is generated. Are scattered by the plate-making film main body, and this scattered light causes appropriate photo-curing in the peripheral portion of the curing section 7, forming a partially cured section 8.

Thereafter, as shown in FIG. 11C, the plate-making film 5 is removed, and then the front surface of the photosensitive layer 2 is subjected to a developing treatment. At this time, the uncured portion of the photosensitive layer 2 is removed (scraped), and the cured portion 7 remains as it is. Further, the partially cured portion 8 is appropriately removed, and thus remains appropriately. Thus, as shown in FIG.
Due to the partially hardened portion 8, a boundary portion W between the convex portion and the concave portion is formed.
₂ is a stereoscopic image sample M ₂ slightly inclined state (smooth state), also the corners C ₂ has a shape slightly rounded rather than right angles rather than obtained in cliff-like. That is, a three-dimensional image sample M ₂ having a concavo-convex shape that is not as sharp as when using the plate making method (1) is obtained. Therefore, it is possible to obtain a stereoscopic image sample that accurately expresses a base material having an uneven shape in which the corners are rounded or gently undulated.

(3) Film front side / indirect arrangement / membrane surface proximity

(5) Film back side, direct arrangement, film surface close arrangement form As shown in FIG. 14 (a), in this case, the photosensitive plate material 1 was used in the plate making method of the above (1) to (4). On the surface of the base film 3
The plate-making film 5 is arranged (attached) such that the image film surface 6 thereof contacts the base film 3. In addition,
At this stage, the protective cover layer 4 has not yet been removed.
Next, as shown in FIG. 14B, the photosensitive plate material 1 (photosensitive layer 2) is inserted from the plate-making film 5 side through the base film 3.
Irradiate ultraviolet rays. Here, in a portion (transparent portion) where the image film surface 6 of the plate-making film 5 is not formed, ultraviolet rays and the like pass through the plate-making film 5 and reach the photosensitive layer 2 to be cured by photo-curing, and a cured portion. Form 7. On the other hand, in the portion (opaque portion) of the plate-making film 5 on which the image film surface 6 is formed, ultraviolet rays and the like are absorbed by the image film surface 6 and do not reach the photosensitive layer 2, and therefore correspond to this of the photosensitive layer 2. The part remains uncured.

After this, as shown in FIG.
Invert the top and bottom of the stencil plate material 1 and store it with the plate-making film 5.
Remove the protective cover layer 4 and develop on the front surface of the photosensitive layer 2.

Therefore, compared to the case of using the plate making method of (1), the stereoscopic image

By the way, as described above, a plate making method in which ultraviolet rays or the like are radiated from the back side (base film side) of the photosensitive plate material 1 through the plate making film 5 and the developing treatment is carried out from the front side of the photosensitive plate material 1 ( In the following, this is referred to as "back side exposure / front side development method"), and the height of the convex portion can be changed by changing the density of the image film surface 6 of the plate-making film 5, that is, the light absorption rate. This will be described below.

For example, as shown in FIG. 15A, the film surface region R _{10 0} (a completely black or opaque region) having a light absorption rate of 100% and the film surface region R ₇₅ (having a light absorption rate of 75%) Dark area), 50% film surface area R ₅₀ (intermediate area),
A plate making film 5 having an image film surface 6 consisting of 25% film surface area R ₂₅ (thin area) and 0% film surface area (completely transparent area) is arranged on the surface of the base film 3. Suppose In this case, the photosensitive plate material 1 is exposed to ultraviolet rays or the like for a predetermined time from the plate-making film side, for example, the time required for the photosensitive layer 2 to complete photocuring when the photosensitive layer 2 is directly irradiated with the ultraviolet rays or the like. When the film surface region R ₀ is irradiated with light for a slightly longer time, the light absorptivity is 0%, so that the portion corresponding to this region is entirely photo-cured to be the cured portion 7 (finally, the portion is completely removed). It becomes a convex part).

Further, in the film surface region R ₁₀₀ , since the light absorption rate is 100%, photocuring does not occur at this portion, and the cured portion 7 is not formed at this portion (finally, the complete concave portion is formed). Will be). Further, in the film surface region R ₇₅ , since the light absorption rate is 75%, only 25% of the ultraviolet rays and the like are applied to this portion as compared with the completely transparent portion, and the photosensitive layer 2 of the photosensitive layer 2 is roughly in accordance with the Lambert-Beer law. Only about 25% of the portion from the back surface (base film side) to the front surface becomes the cured portion 7 by photo-curing.
Similarly, in the film surface regions R ₅₀ and R ₂₅ , approximately 50% from the back surface to the front surface of the photosensitive layer 2, respectively.
Only 75% of the portion becomes the cured portion 7 by photo-curing.

After this, as shown in FIG.

Also in this case, as in the case of the plate making method of (5), it is possible to form a convex portion having an arbitrary height.

After that, as shown in FIG. 19, a hard lightweight backing material 10, such as urethane resin, polyethylene resin, acrylic resin, is formed on the back surface of the three-dimensional image sample produced by any of the plate making methods described above. A foam such as styrene resin is attached. The lightweight backing 10 can significantly increase the strength of the three-dimensional image sample without significantly increasing the weight. Thus, a highly durable stereoscopic image sample that accurately represents the shape of the substrate can be obtained.

Then, as shown in FIG. 20, the front surface of the three-dimensional image sample is coated with one or more colors using a desired coating material to form a coating film 11, and the coating film 11 is further formed.
The desired coating material is used to apply one-color or multi-color coating having a design property to form the design coating film 12, and the coated three-dimensional image sample board is completed. Thus, a painted three-dimensional image sample board that accurately expresses the color tone, shape, etc. of the design painted board can be obtained.

The method for creating a stereoscopic image form according to the present invention will be described below. FIG. 21 (a) shows a method for manufacturing a stereoscopic image form according to the present invention, in which a stereoscopic image form is manufactured based on digital image data of an original image having a design property or an image of an original base material. It is a flowchart. Note that FIG. 21B is a flowchart showing a conventional method for manufacturing a stereoscopic image formwork. As shown in FIG. 21A, in the method of manufacturing a stereoscopic image form according to the present invention, digital image data is prepared in step U1 and gradation reproduction processing is performed on the digital image data in step U2. Then, gradation correction processing is performed in step U3, and a plate-making film is prepared in step U4. Or Steps S1 to S in the manufacturing process of the painted three-dimensional image sample board
This is the same as each process in 4. The order of the tone reproduction process of step U2 and the tone correction process of step U3 may be interchanged. However, in the following points, steps U1 to U4 in the manufacturing process of the stereoscopic image form are different from steps S1 to S4 in the manufacturing process of the stereoscopic image sample.

That is, in the manufacturing process of the three-dimensional image sample shown in steps S1 to S4 in FIG. 1, the original image is simulated based on the digital image data corresponding to the original image (simulation image) of the design coated plate having the design property. A plate-making film corresponding to the image itself is created. Then, after that, flexo plate making is performed based on the plate making film, and a stereoscopic image sample having a shape corresponding to the original image or the same shape is manufactured.

On the other hand, in the manufacturing process of the stereoscopic image form shown in steps U1 to U4 in FIG.
A plate-making film corresponding to a reverse image of an original image or the like is created based on digital image data corresponding to a reverse image of an original image having a design property or an image of an original base material (hereinafter referred to as “original image etc.”). To be done. Then, after this, as described later, a three-dimensional relief image plate making is performed based on the plate making film, and a three-dimensional image form (female mold) having a shape in which irregularities are reversed from the original image or the original base material is produced. It
Note that digital image data corresponding to an inverted image such as an original image can be easily created (inverted) by subjecting the digital image data corresponding to the original image or the like to simple arithmetic processing with an imagesetter. .

Regarding other points, for example, arithmetic processing of digital image data, gradation reproduction, gradation correction, film production, etc., step U1 in the manufacturing process of the stereoscopic image form.
The processing method in U4 to U4 is substantially the same as that in steps S1 to S4 in the manufacturing process of the stereoscopic image sample, and thus detailed description thereof will be omitted.

Thus, in step U5, step U1
~ 3D relief image plate making is performed using the plate making film made through U4, and further, in step U6, the mold surface of the 3D relief image is subjected to surface release treatment, and unevenness is reversed from the original image or the original substrate. A stereoscopic image form having the above shape is manufactured. According to this method of creating a stereoscopic image form,
Digital image data of an extremely large number of base material patterns or design patterns created by a designer or the like without manufacturing actual materials as in the case of the conventional method of creating a stereoscopic image form as shown in FIG. For example, based on 1 million kinds of two-dimensional infinite arbitrary design data), a stereoscopic image form can be directly and easily and quickly created at low cost.

As shown in FIG. 21 (b), in the conventional method for producing a stereoscopic image formwork, first, an actual material (for example, natural stone, brick, etc.) having a design-like male irregular surface having a predetermined shape is used. Etc.) are prepared (step U11), and the silicon resin is pressure-bonded to the male concave-convex surface of the actual material, and then the silicon resin is cured (step U1).
2). After that, the cured silicone resin is released from the actual material to obtain a silicone stereoscopic image mold having a female concave-convex surface as a mold surface (step U13). However, in the conventional method of creating a stereoscopic image formwork, as described above, in order to manufacture a base material or a building material of a new shape corresponding to a new original base material, first, a cutting process of natural stone,
Since the actual material has to be produced by hand such as clay work or carving of wood, there is a problem that a great deal of labor or skill is required to produce the actual material.

Hereinafter, the plate making method of the three-dimensional relief image plate making in step U5 and the surface releasing treatment method of step U6 will be specifically described. The plate making method and the photosensitive plate material in this three-dimensional relief image plate making are Substantially the same as those in the production of the stereoscopic image sample described above, except that the film corresponds to an inverted image such as an original image. Therefore, in order to avoid duplication of the description, the description of the items common to the case of producing the stereoscopic image sample will be omitted in principle. Also in the three-dimensional relief image plate making in the manufacture of this three-dimensional image form, the following eight forms can be used as the plate making form, as in the case of the flexible seed plate making in the manufacture of the three-dimensional image sample. Note that these plate making forms may be combined. (1) Film front side / direct arrangement / membrane surface close arrangement form (2) Film front side / direct arrangement / membrane surface separation arrangement form (3) Film front side / indirect arrangement / membrane surface close arrangement form (4) Film front side / indirect arrangement・ Membrane surface separation arrangement form (5) Film back side ・ Direct arrangement ・ Membrane surface close arrangement form (6) Film back side ・ Direct arrangement ・ Membrane surface separation arrangement form (7) Film back side ・ Indirect arrangement ・ Membrane surface close arrangement form (8) ) Film backside, indirect arrangement, membrane separation arrangement

The plate making method or the surface release treatment method in these plate making modes will be specifically described below. (1) Film Front Side / Direct Arrangement / Membrane Surface Proximity Arrangement Form As shown in FIG. 22 (a), in this case, first, the protective cover layer 4 is removed, and then the photosensitive layer 2 exposed to the outside.
A plate-making film 5 having an image corresponding to a reverse image such as an original image is arranged on the front surface of the so that the image film surface 6 thereof contacts the photosensitive layer 2. Next, as shown in FIG. 22B, the photosensitive plate material 1 is irradiated with ultraviolet rays or the like from the plate-making film 5 side. Here, in a transparent portion of the plate-making film 5 on which the image film surface 6 is not formed, ultraviolet rays or the like pass through the plate-making film 5 and reach the photosensitive layer 2, which is cured by photocuring, and the cured portion 7 is formed. Form. On the other hand, in the portion of the plate-making film 5 where the image film surface 6 is formed, ultraviolet rays and the like do not reach the photosensitive layer 2, and the portion of the photosensitive layer 2 corresponding thereto remains uncured.

After that, as shown in FIG. 22C, the plate-making film 5 is removed, and the front surface of the photosensitive layer 2 is subjected to a developing treatment such as scraping with a brush. At this time, the uncured portion of the photosensitive layer 2 is removed, while the cured portion 7 remains as it is. Thus, as shown in FIG. 22D, the image displayed on the plate-making film 5, that is, the female concave-convex surface 1 corresponding to the concave-convex inverted shape of the original image or the original substrate.
3 is formed. In this case, the corners are almost right-angled, and the boundary between the convex and concave is almost cliff-like, as in the case of manufacturing a stereoscopic image sample with the film front side, direct arrangement, and film surface close arrangement. As a result, a sharp female concave-convex surface 13 is formed.

Then, as shown in FIG. 22 (e), a surface release treatment is performed on the female concave-convex surface 13 using a release agent 14 such as a silicone resin or a fluororesin, and the three-dimensional image frame 1 is formed.
Get 5. The release treatment is performed by a method such as applying a release treatment agent 14 such as a silicone resin or a fluororesin to the uneven surface 13 to form a thin release treatment agent layer 14.

(2) Film Front Side / Direct Arrangement / Membrane Surface Separation Arrangement As shown in FIG. 23 (a), in this case, the protective cover layer 4 is first removed, and then the front surface of the photosensitive layer 2 is Plate-making film 5 having an image corresponding to a reverse image of the original image
Are arranged in such a manner that the image film surface 6 faces the direction (outside) opposite to the photosensitive layer 2. Next, as shown in FIG. 23B, the photosensitive plate material 1 is irradiated with ultraviolet rays or the like from the plate-making film 5 side. Here, in a transparent portion of the plate-making film 5 on which the image film surface 6 is not formed, ultraviolet rays or the like pass through the plate-making film 5 and reach the photosensitive layer 2, which is cured by photocuring, and the cured portion 7 is formed. Form. On the other hand, basically, in the portion where the image film surface 6 of the plate-making film 5 is formed, ultraviolet rays and the like do not reach the photosensitive layer 2, and therefore the portion of the photosensitive layer 2 corresponding thereto remains uncured. . However, in this case, until the ultraviolet rays or the like that have passed through the image film surface forming portion of the plate-making film 5 pass through the transparent main body of the plate-making film 5 and reach the photosensitive layer 2, a part of the ultraviolet rays or the like is generated. Are scattered by the plate-making film main body, and this scattered light causes appropriate photo-curing in the peripheral portion of the curing section 7, forming a partially cured section 8.

After that, as shown in FIG. 23C, the plate-making film 5 is removed, and then the front surface of the photosensitive layer 2 is subjected to a developing treatment. At this time, the uncured portion of the photosensitive layer 2 is removed, and the cured portion 7 remains as it is. Further, the partially cured portion 8 is appropriately removed, and thus remains appropriately. Thus, as shown in FIG. 23 (d), the partially hardened portion 8 causes the boundary portion between the convex portion and the concave portion to have a slightly inclined state (smooth state) rather than a cliff-like shape, and the corner portion. The female concave-convex surface 13 having a slightly rounded shape instead of a right angle is formed. Then, as shown in FIG. 23 (e), the female mold concavo-convex surface 13 is subjected to a surface release treatment using a release treatment agent 14 such as a silicone resin or a fluororesin to obtain a stereoscopic image mold 15. In this case, a stereoscopic image mold 15 having a female concave-convex surface 13 that is not as sharp as when using the plate making method (1) is obtained. Therefore, it is possible to obtain a three-dimensional image frame that accurately corresponds to the original image or the inverted product of the original base material having the uneven shape in which the corners are rounded or gently undulated.

(3) Other Film Arrangement Modes In addition to the plate making method or surface releasing treatment method according to the above film front side / direct arrangement / membrane surface proximity arrangement form and film front side / direct arrangement / membrane surface separation arrangement configuration, As in the case of the plate-making method for a stereoscopic image sample, plate making can be performed using other film arrangement forms. That is, the photosensitive plate material 1, the plate-making film 5, and the intermediate film 9 are arranged and exposed (irradiated with ultraviolet rays or the like) in the forms as shown in FIGS.・ Indirect arrangement ・ Membrane surface close arrangement form, film front side ・ Indirect arrangement ・ Membrane surface separation arrangement form, film backside ・ Direct arrangement ・ Membrane surface close arrangement form, film backside ・ Direct arrangement ・ Membrane surface separation arrangement form, Film backside ・ Indirect Plate making can be performed according to the arrangement, the film surface close arrangement form, the film back side, the indirect arrangement, and the film surface separation arrangement form. The shape characteristics of the female concave-convex surface 13 formed by plate making in these film arrangement forms are the same as those in the case of using the corresponding film arrangement forms in the plate making of the stereoscopic image sample.

A method for producing a duplicate stereoscopic image sample of an original image or an original substrate using the stereoscopic image frame 15 thus produced will be described below with reference to FIG.
As shown in FIG. 25, in the manufacturing process of this duplicate stereoscopic image sample, first, the foamable urethane 16 is poured onto the mold surface (female surface 13 of the female mold) of the stereoscopic image frame 15, and the foamable urethane 16 is removed. It is cured (step A1). Next, the cured foamable urethane 16 is released from the three-dimensional image mold 15 to obtain a lightweight urethane replica 16 having the same shape as the original image or original substrate (step A2). Further, instead of the foaming urethane, a liquid photopolymerizable composition may be used for photocuring.

After that, one-color or multi-color coating with a desired paint is applied to the mold surface of the urethane replica 16 (male uneven surface having a design property) to form a coating film 17. A desired coating material is applied onto the coating film 17 to form a design coating film 18 by applying a coating having a one-color or multi-color design property, and the three-dimensional sample image 19 for coating reproduction is completed. In this way, a paint duplicate stereoscopic image sample that accurately represents the shape, color tone, etc. of the original image or original substrate can be obtained.

Hereinafter, with reference to FIG. 26, a method for producing a die using the stereoscopic image mold 15 and producing an original image or a duplicated stereoscopic image of an original substrate by press molding using the die will be described. explain. As shown in FIG. 26, in the process of producing the duplicate stereoscopic image, first, the plaster 20 which is a heat-resistant material is poured onto the mold surface (female concave and convex surface 13) of the stereoscopic image mold 15 to solidify the plaster 20. (Step F1). Subsequently, the solidified gypsum 20 is released from the three-dimensional image mold 15 to obtain a gypsum mold 20 (heat resistant mold) having a male concave-convex surface as a mold surface (step F2). Next, after the molten iron 21 is poured into the mold surface (male uneven surface) of the plaster mold 20, the molten iron 21
Is solidified (step F3). After that, the solidified iron is released from the gypsum mold 20 to obtain the mold 21 having the female concave and convex surface as the mold surface (step F4).

Further, using the mold 21, press-molding is performed on a semi-solidified plastically deformable material (ceramic material), for example, semi-solidified concrete (step F5). Subsequently, the metal mold 21 is removed from the plastically deformable material 22 (ceramic material), or the plastically deformable material 22 (ceramic material) is taken out from the metal mold 21 to have the same shape as the original image or the original base material. A duplicate stereoscopic image 22 of is obtained (step F6).

Thereafter, the mold surface of the duplicated stereoscopic image 22 (male uneven surface having a design property) is coated with one or more colors using a desired coating material to form a coating film 23. A desired coating material is used to apply a coating having a single color or a multicolor on the coating film 23 to form a design coating film 24, and a three-dimensional image 25 of duplicate coating is completed. In this way, a painted duplicate stereoscopic image that accurately expresses the color tone, shape, etc. of the original substrate or original image can be obtained.
