<Embodiment 1>
<Outline of Embodiment 1>
The invention in the present embodiment is a printed matter (sheet-like matter, the same applies hereinafter) capable of expressing a pattern by a watermark, although there are only two metal layers.
FIG. 1 is a conceptual diagram of an example of the invention of the present embodiment, and shows an example of a visual view of the front surface (0101) and the back surface (0102) of the printed matter in the present embodiment. The crescent pattern (0105) drawn in the center shown in the figure is a pattern drawn with gold leaf stamped on a metal foil. When viewed from the surface, the crescent moon pattern drawn in the center can be seen as clearly as each crescent moon drawn on the left and right. On the other hand, when viewed from the back side, the crescent moon pattern drawn in the center can be seen through, unlike the crescent moons drawn on the left and right. Since it is a drawing that can be seen through, its appearance is different from that seen from the surface, and it is not clearly visible.

<Structure of Embodiment 1 Invention>
As shown in FIG. 2, the invention of the first embodiment includes a transparent plastic sheet (0201), a metal foil (0202), a transparent protective layer (0203), an ink pattern (0204) on the transparent protective layer, and a metal foil. It is a printed matter composed of a pattern (0205) and a transparent plastic sheet other side ink pattern (0206).

<Explanation of Embodiment 1 Configuration>
<Embodiment 1 Transparent Plastic Sheet>
The "transparent plastic sheet" is preferably made of a material capable of directly printing the transparent plastic sheet side ink pattern (0206). Examples of the material include PET, polyethylene, polystyrene, acrylic resin, AS resin, polycarbonate, and the like. As long as it is transparent, it may be colored. The transparent plastic sheet has high light transmission, and the transmission does not change depending on the thickness. Therefore, the thickness of the transparent plastic sheet is not limited, but about 0.1 mm or more and 1 mm or less is suitable for clearly expressing the watermark pattern.
As will be described later, the transparent plastic sheet is coated with an adhesive for attaching a metal foil on one surface, and the sheet surface is directly printed with ink on the other surface.

<Embodiment 1 Metal Leaf>
The "metal leaf" is adhered to one surface of the transparent plastic sheet with an adhesive (0207).
In the present embodiment, although not shown in the figure, for example, two pieces of square gold leaf having a length of about 7.5 cm or more and another piece having a length of about 8 cm or more are used as a transparent plastic sheet. Metal leaf is attached to one side of the transparent plastic sheet by arranging it so that it does not overlap and there is no gap. Depending on the size of the transparent plastic sheet or the size of the prepared metal leaf, you may combine multiple metal foils and attach them to the transparent plastic sheet, or put one metal leaf on the transparent plastic. You can paste it on. When a plurality of metal foils are used, it is preferable to attach them so that the metal foils do not overlap. Furthermore, the surface to be attached should be unified to one surface of the transparent plastic sheet, or the metal leaf should not be attached to both surfaces of the transparent plastic sheet in the part expressing the watermark pattern. is there. The act of sticking metal leaf on a transparent plastic sheet with an adhesive is not foil stamping.
The adhesive used to attach the metal foil to the transparent plastic sheet may be of any kind as long as it can maintain a transparent state when dried.

The metal foil having a thickness of 0.05 μm or more and 0.5 μm or less is suitable. If a metal foil of 0.05 μm or less is used, the gold leaf is likely to be torn when the pressure is applied by tracing with a finger when pasting, or the gold leaf is easily torn at the stage of arranging the transparent protective layer after pasting. There is a danger of becoming. Further, by thinning the metal foil, the metal foil allows light to pass through. In the present embodiment, by reducing the thickness of the metal foil to 0.5 μm or less, the metal foil becomes thin enough to transmit light. As a result, the light from the front surface appears to pass through the metal foil, but it becomes difficult to distinguish the shade of ink printed on the front surface on the back surface.
In particular, when printing with fine ink (0211) is studded on the transparent plastic sheet on the back surface, the printing on the front surface is disturbed and the printing on the front surface becomes more difficult to identify. Sprinkling fine prints means printing fine straight lines and curves in parallel at close intervals. This interval is about 0.1 mm to 0.3 mm, and the line width is also about the same. If the back surface side corresponding to most of the back surface side or the printed portion of the front surface is modified with such a pattern, the printed pattern on the front surface side becomes difficult to see from the back surface side.

As will be described later, the watermarked printed matter is configured so that the metal leaf pattern arranged on the front surface can be visually recognized even from the back surface by the watermark technique. Hot stamping foil is used for this metal foil pattern. The hot stamp foil is obtained by laminating a release layer, a coloring layer, a vapor deposition layer, and an adhesive layer in this order on a base film, and a predetermined mold having a pattern on a transparent protective layer on the surface is heated to a predetermined high temperature. A metal leaf pattern is formed by pressing from the base film side with pressure. This pattern is composed of large and small thicknesses. The thickness of the colored layer, the vapor-deposited layer, and the adhesive layer is about 0.03 μm to 0.07 μm. The printing on the back side should not be placed in the area where the metal leaf pattern is arranged so that the metal foil pattern can be seen through well from the back side. In this hot stamping foil stamping process, temperature and pressure are also applied to the metal foil on the transparent plastic sheet on the front side, and the pattern is transferred. Therefore, the pattern is composed of two layers of metal foil. This portion is configured so that printing is not performed on the transparent protective layer on the front surface side, and the pattern composed of the two layers of metal foil can be observed from the back surface side as well.
In summary, the printing on the transparent protective layer on the front side is a metal leaf on the transparent plastic sheet, and it is difficult to penetrate to the back side due to the flat part, but the metal leaf pattern on the front side is the metal foil on the transparent plastic. Since it is formed in an uneven shape including the metal leaf, it can be easily observed from the back surface side. In other words, it will be recognized as a watermark pattern. In addition, a fine pattern is configured so that the printing on the front side is difficult to see from the back side. The unevenness formed on the hot stamp foil and the metal foil by the unevenness of the mold is preferably formed so that the difference in thickness between the non-unevened portion and the uneven portion is between 20% and 50%. The difference in light transmission caused by the difference in thickness is used to form light and shade in the watermark pattern. Areas with low transparency are darker than areas with high transparency.

In the present embodiment, there are an ink pattern on the transparent protective layer and an ink pattern on the other side of the transparent plastic sheet, and it is assumed that each ink pattern has a different pattern. Therefore, if the ink pattern on the transparent protective layer is transparent to the ink pattern side on the other side of the transparent plastic sheet, or if the pattern on the ink pattern side on the other side of the transparent plastic sheet is transparent to the ink pattern side on the transparent protective layer, the ink pattern is transparent. It is disturbed by the transparent ink pattern, and the pattern drawn by the ink pattern cannot be beautifully expressed. Although the metal foil transmits light, it is not 100% transparent. Therefore, when the thickness is 0.05 μm or more, the ink pattern printed on one side is printed on the other side. It is not so transparent that it makes it difficult to see. When the metal foil is made thinner than 0.05 μm, the light transmission is increased as compared with the case of 0.05 μm, and the ink pattern printed on one side becomes more transparent to the other side, and gradually the other side. It becomes difficult to see the ink pattern printed on the surface of.

The constituent component of the metal foil may be a metal foil in which a plurality of metals are mixed, or may be a metal foil composed of only one kind of metal. The printed matter of the present invention may be used as a bookmark or a postcard. In the case of applications such as bookmarks and postcards, it is expected that the printed matter will break or bend to some extent, so if the metal leaf is hard, it will break or peel off from the transparent plastic sheet. Therefore, it is necessary to determine the components so that the metal leaf is soft. Alternatively, when used as an exhibit such as colored paper or painting, use hard metal leaf so that it will not be folded or bent, but rather chased or bent to maintain the state of the work. Is preferable.

For example, when gold leaf is selected as the metal foil to make an exhibit, it is configured to be in the range of 93 to 96% gold, 3 to 6% silver, and 0.5 to 1% copper. It is conceivable to use a gold leaf having a thickness of 0.05 to 0.3 μm. If the proportion of gold is less than 93%, the color of gold will be dull. If the gold content is greater than 96%, the metal leaf will be too soft. If the silver content is less than 3%, the metal leaf will be too soft. If the proportion of silver is greater than 6%, the metal leaf becomes too hard. If the component ratio of copper is less than 0.5%, the color of the metal foil deteriorates. If the proportion of copper is greater than 1%, the metal leaf is prone to discoloration. If the thickness of the metal leaf is thinner than 0.05 μm, the surface of the metal leaf will be exposed due to impacts such as tracing the metal leaf during processing, rubbing something, or hitting something during the exhibition as described above. It is easily damaged and torn. When the thickness of the metal foil is 0.2 μm or more, the light transmission of the metal foil becomes low, the difference in transparency from the watermark portion becomes small, and the difference in transparency is used for expression. The watermark pattern is lighter.

<Embodiment 1 Transparent Protective Layer>
The "transparent protective layer" protects the surface of the metal leaf. Therefore, it is configured to cover the surface of the metal foil attached to one surface of the transparent plastic sheet with an adhesive. The transparent protective layer is intended to prevent the surface of the metal foil from being scraped. Therefore, the thickness of the transparent protective layer is preferably at least one that does not scratch the surface of the metal foil during normal use, and preferably about 0.02 mm or more and 0.1 mm or less.
The transparent protective layer may be formed by attaching a sheet-like material to the surface of the metal foil, or by applying a liquid material to the surface of the metal foil and drying it, or a mist. It may be constructed by injecting a shape onto the surface of a metal foil. Other methods may be used.
The transparent protective layer is preferably colorless and transparent so as not to discolor the material of the metal foil, but it may be colored as long as it is transparent. Specific examples of the transparent protective layer include a urethane-based top coat.

<Implementation 1 Ink pattern on the transparent protective layer>
The "ink pattern on the transparent protective layer" is printed on the transparent protective layer. For example, it is conceivable to print by an inkjet method. The print color may be any color. In order to prevent the printed ink from bleeding, it is preferable to use an oil-based ink or an ink having a high quick-drying property. Printing was performed after protecting the metal leaf attached to the transparent plastic sheet with a transparent protective layer, or, if the transparent protective layer is a sheet, first printing on the transparent protective sheet and then printing. Place a transparent protective sheet on the metal leaf.

<Embodiment 1 Metal leaf pattern>
The "metal leaf pattern" constitutes a watermark when viewed from the other side, which is foil-pressed on the transparent protective layer. As described above, hot stamping foil is used for the metal foil pattern. The hot stamp foil is obtained by laminating a release layer, a coloring layer, a vapor deposition layer, and an adhesive layer in this order on a base film, and a predetermined mold having a pattern on a transparent protective layer on the surface is heated to a predetermined high temperature. A metal leaf pattern is formed by pressing from the base film side with pressure. This pattern is composed of large and small thicknesses. The thickness of the colored layer, the vapor-deposited layer, and the adhesive layer is about 0.03 μm to 0.07 μm. The printing on the back side should not be placed in the area where the metal leaf pattern is arranged so that the metal foil pattern can be seen through well from the back side. In this hot stamping foil stamping process, temperature and pressure are also applied to the metal foil on the transparent plastic sheet on the front side, and the pattern is transferred. Therefore, the pattern is composed of two layers of metal foil. This portion is configured so that printing is not performed on the transparent protective layer on the front surface side, and the pattern composed of the two layers of metal foil can be observed from the back surface side as well. The difference in thickness between the non-concavo-convex portion and the uneven portion is about 20% to 50% in the unevenness formed on the hot stamp foil and the metal foil by the unevenness of the mold. The difference in light transmission caused by the difference in thickness is used to form light and shade in the watermark pattern. Areas with low transparency are darker than areas with high transparency.

As shown in FIG. 2, in the stamping process of the hot stamping foil, temperature and pressure are also applied to the metal foil on the transparent plastic sheet on the surface side, the pattern is transferred, and the pressured portion (0208) is transparent. In the portion (0209) that is dented in the plastic direction and (almost) no pressure is applied, the metal leaf is not (almost) dented in the transparent plastic direction. In this way, unevenness is generated in the same shape as the mold. Further, the metal foil pattern has parts having different thicknesses in accordance with the pattern of the mold transferred in the stamping process of the hot stamping foil. In the figure, a> b> c> d, and the thickness of the recessed b, c, and d portions is about 20% to 50% as compared with the non-dented metal leaf pattern a portion (0210). Become. The pattern part that is transferred by applying temperature and pressure to the metal foil on the transparent plastic sheet on the front side matches the unevenness of the metal leaf pattern, and is transparent located below the part where the metal leaf pattern is recessed. The metal leaf on the plastic is dented. The portions where the metal foil is recessed are f, g, and h in the figure. Since the transparent plastic sheet is not dented, the thickness of the metal foil on the transparent plastic sheet differs depending on the thickness of the dent in the portion where the metal foil is dented and the portion where the metal foil is not dented. In the figure, the thickness of the metal foil on the transparent plastic sheet is e> f> g> h. Due to the difference in thickness, the transparency is different, so that the watermark pattern is different. The larger the thickness, the lower the transparency and the deeper the watermark pattern is expressed, and the smaller the thickness, the higher the transparency and the lighter the watermark pattern. The thickness of the metal foil pattern portion is a + e> b + f> c + g> d + h. As for the density of the watermark pattern, the a + e portion is relatively darkest, the b + f portion is relatively darkest, the c + g portion is relatively second thin, and the d + h portion is relatively lightest. By using the shades of the openwork, for example, delicate and detailed depictions of people such as facial expressions and hairstyles, eyes, nose, mouth, wrinkles, and the light of the tips and shafts of flower petals. Delicate and detailed depictions of things such as shadows, stamens, pistils, and stems, and the perspective of a landscape where the things in the foreground are drawn with clear lines and the things in the back are drawn with thin lines are expressed by watermark patterns. It becomes possible to do.

In order not only to see through the metal leaf pattern part but also to realize detailed depiction by watermarking the metal foil pattern part, it is necessary to have a thick part and a thin part in the metal leaf pattern part, and to compose this. It is necessary that a material whose thickness changes easily depending on pressure is arranged below the metal leaf pattern portion. Therefore, in order to create the watermark pattern printed matter, it is necessary to make sure that the metal foil pattern is arranged on the metal foil.

<Embodiment 1 Transparent plastic sheet, other surface ink pattern>
The "transparent plastic sheet other side ink pattern" is printed on the other side of the transparent plastic sheet, unlike the ink pattern described above. Printed directly on the surface of the transparent plastic sheet. The ink is preferably oily in order to prevent it from bleeding or disappearing due to rubbing. Ink printing on the other side of the transparent plastic sheet must be performed after the transparent protective layer is placed on the metal leaf pasted on the transparent plastic sheet, or before the metal foil is pasted on the transparent plastic sheet. This is because if the transparent plastic is printed on the other side after the metal foil is applied and before the transparent protective layer is placed, the metal foil attached on the transparent plastic will be peeled off or scraped off.

<Outline of Embodiment 3>
The invention of the present embodiment is a printed matter in which the sticking marks formed when the metal leaf is stuck to the transparent plastic sheet using an adhesive are formed as a pattern as if it were a kind of pattern. is there.
<Structure of Embodiment 3 Invention>
A watermark pattern is formed by pressing when the metal foil is adhered to one surface of the transparent plastic sheet with an adhesive. When attaching the metal leaf, make sure that one point, for example, the edge of the metal leaf, is not wrinkled on the metal leaf or that air or dust gets between the transparent plastic sheet and the metal leaf and causes unevenness on the surface of the metal leaf. After adhering, it will be adhered little by little by tracing the periphery. At that time, apply pressure from above so that the metal leaf adheres firmly. For example, using a finger or a jig to press and trace the metal leaf. This pressing and the movement of tracing the metal leaf create a pattern-like mark on the metal leaf.

The present embodiment is an invention relating to a method for producing a watermarked printed matter.
<Structure of Embodiment 4 Invention>
FIG. 6 is a flow chart showing an example of a method of manufacturing a watermarked printing unit of the present implementation girder. As shown in the figure, the printing method of the watermarked printed matter includes a metal leaf bonding step (0601), a transparent protective layer setting step (0602), a one-side ink pattern printing step (0603), and a metal leaf pattern foil pressing step (0604). ) And the other side ink pattern printing step (0605).

<Explanation of Embodiment 4 Configuration>
<Embodiment 4 Metal Leaf Adhesion Step>
The "metal leaf bonding step" is a step of adhering to one surface of a transparent plastic sheet with an adhesive. Metal leaf is not adhesive in itself. In order to adhere to other materials such as transparent plastic sheets, an adhesive material with adhesive strength is applied between the transparent plastic sheet and the metal foil, and the applied adhesive is applied before it dries. It is necessary to place the metal foil on top of the layer and bond it.

<Embodiment 4 Transparent Protective Layer Setting Step>
The "transparent protective layer setting step" is a step of setting a transparent protective layer that protects the surface of the adhered metal foil. The transparent protective layer may be set to be applied on a metal foil, may be set to be sprayed, or may be set by sticking a sheet. If the transparent protective layer is not set evenly, the protective function will be insufficient after all, so it is preferable to use a method of coating or pasting a sheet.

<Embodiment 4 One-sided ink pattern printing step>

<Embodiment 6 Watermark Substep>
The "watermark pattern sub-step" is a step of forming a watermark pattern by pressing the metal leaf when it is adhered to one surface of a transparent plastic sheet with an adhesive in the metal leaf bonding step. When the metal leaf is bonded and bonded, simply placing the metal leaf on the layer of the adhesive is not sufficient for adhesion, and the metal is wrinkled, and air and dust are caused by the layer of the adhesive and the metal. It may get in between the foils and cause irregularities on the surface of the metal foil. Therefore, when affixing a metal foil, it is necessary to bond one point and then gradually bond the metal foil from that point. When the metal leaf is gradually spread, the metal leaf is pressed so as to be strongly adhered to the adhesive, so that a watermark pattern corresponding to the movement of the pressing is formed.
