Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a layout system that performs plate making of commercial printed matter such as leaflets by computer processing.

(Prior art) In recent years, along with the color separation of documents using scanners, printed matter 1
A layout system for printing plate making that synthesizes image data for pages through computer processing is used in the field of printing plate making. This layout system is a scanner connected to a computer with page editing functions.
Image data taken in by a scanner is given to the computer, subjected to processing such as layout, and then output to the scanner.

FIG. 15 is a schematic diagram showing the configuration of a general layout system for printing plate making, in which 160 is a layout section, 170 is a tablet digitizer, and 180 is a scanner section. As shown in the figure, the layout section 160 is a computer 161 and the memo connected to this January 62.
163 , a display 164 , a pointing device 165 and a keyboard 166 , and the tablet digitizer 170 has a cursor 171 and an input surface 17 .
2, and a mount area 173 and a menu area 174 are set on the input surface 172. The scanner section 18o is composed of an input drum 181, an output drum 182, and an ink face 185, 186.
5.186 is connected to the computer 161. Note that the computer 161 includes an input computer, a layout computer, and an output computer (all not shown).

In this layout system, the layout work of image data is performed in the following manner based on various manuscripts, layout designation sheets, and other instructions. The original is pasted at an angle, and the image data of the original is taken into the input computer (not shown) of the computer 161 via the ink face 185 and stored in the memory 162. Image data is imported from the manuscript for an area slightly larger than the actual trimming area based on the layout specification sheet (not shown).
Accurate trimming is later performed using a layout computer (not shown) of computer 161.

The memo 62 on which the image data has been written is disconnected from the input computer and connected to the layout computer. As a result, the image data written in the memory 162 is displayed on the display 164. The operator observes this displayed image and operates the pointing device 165 while referring to the layout specification sheet to move the cursor and specify the trimming range, the position of the rope tie, etc. Further, the keyboard 166 is used to specify the printing surface color, halftone percentage, etc.

The data that has been layout processed according to these specifications is written to the memo In63, so after the writing is completed, the data is
63 is disconnected from the layout computer and connected to an output computer (not shown) of computer 161. As a result, the data for Memo January 63 is taken out via the output computer and the ink face 186, and the trimmed and laid out image is output onto the film set on the output drum 182 of the scanner section 180.

Furthermore, the above operations performed using pointing device 165 and keyboard 166 can also be performed by operating tablet digitizer 170. That is, the above-mentioned layout designation paper is set on the mount area 173 of the tablet digitizer 170, and the cursor 171 is operated to select the position data of the picture drawn on the layout designation paper and various menus set in the menu area 174. Just enter it.

By the way, unlike general printed matter, printed materials for advertising products called flyers are printed only on the subject portions that appear in the manuscript, and in extreme cases these subject portions overlap each other. It is characterized by the fact that there are many

Figure 16 is a schematic diagram showing the designated layout paper on which the specification format of the leaflet printed material is drawn. The figure E6 consists of the figure E6, and the figure [! 3, E4, E5, E7,
E8, E9, Ell, E12, and figures E1, E2, and EIO indicating the frame of the m (1i1 square) portion are drawn. Further, in the figures E1, E2, and EIO, plain halftone information indicating the halftone percentage of each color is written.

As shown, shapes E3, E4, E5, E7, E8, E9
, Ell, and E12 indicate the outline of the subject portion of the document, and only the subject of the corresponding document will be printed in this portion. To perform this with the layout device shown in FIG. 15, it is necessary to perform a cutting operation to extract only the subject part from the rectangular image data containing the subject part of the document stored in the memory 162. There is.

FIG. 17(a), 忤) is a schematic diagram for explaining this cutting operation, and here, the cutting operation of the image data of the document corresponding to figure E7 in FIG. 16 will be explained. The cutting operation is performed by operating the pointing device 165 on the image 11 displayed on the display 164, as shown in FIG. 17(a), and moving the cursor 167 along the outline of the person in the image 1. This is done by

However, the image 11 displayed on the display 164 is a display of the whole image by thinning out the image in the memory 162, and when the cursor 167 is operated on this whole image, the darkness of the outline becomes worse. There is a problem.

For this reason, for printed matter that requires high quality, the first
7. As shown in FIG. 7(b), move the cursor 1 to the enlarged image ■2, which is a partially displayed image in the memory 162 without thinning out the image.
67 must be moved to perform the above-mentioned cutting operation.

(Problems to be Solved by the Invention) However, such a cutting operation performed by displaying the entire image or partially enlarged image on a display and operating a cursor has the drawback that it is complicated and time-consuming. In particular, for printed matter such as flyers, the format of the designated paper, the types of products to be featured on the flyer, and their selling prices are often not determined until the flyer is due to be distributed, and the time spent on plate making and printing is limited to magazines, etc. The actual situation is that the number of documents is extremely small compared to general printed matter, and the time from submission to plate making, printing, and delivery is only a few days. However, there is a problem in that the delivery date cannot be met if the product is not delivered in time.

Additionally, some layout systems have a function that automatically cuts out the image by using the difference in density between the subject and its background, but if there is a clear difference in density due to the outline of the subject. There is a problem in that there are only a few such documents, and while it is possible to automatically cut out a portion of the image, the remaining portions must be cut out as described above.

In this way, the layout system shown in FIG. 15 cannot be applied to the plate-making process for printed matter such as flyers.
In reality, the layout is done manually using various masks, and the reality is that the rationalization of leaflet making has been delayed.

The present invention has been made in view of the above-mentioned problems, and it provides rough cutout data to a layout system, performs layout processing for one page of printed matter based on this cutout data, and creates a final original. The purpose is to create a preliminary separation.

Note that such a magnification measuring means 11 is well known.

FIG. 3 is a flowchart for explaining the control operation of the computer 30, and FIGS. 4(a) and 4(b) show the relationship between the position data input from the data tablet 20 to the computer 30 and the position data in the first layout data. This is a schematic diagram for explaining the relationship, and the operations of creating the first layout data and creating the C)W will be described below based on the diagram.

First, regarding the document to be measured, wait for the document Nα, separation Nα, and scanner resolution to be input from the keyboard 31 (Sl), and once input, the magnification data from the magnification measuring means 11 etc. and the position data from the data tablet 20 are input. is input (S2). The separation Nα is input by the operator by determining the overlapping state of figures drawn on the designated layout paper, but for the designated layout paper shown in FIG. , El
1 and E12 overlap or are close to each other. The scanner resolution is inputted as a predetermined value, which is usually 10 to 20 lines/screen. Inputting the magnification data is done by matching the projected image of the document with the figure on the layout designation sheet B as described above, or by inputting the value displayed on the magnification display 18 directly from the magnification measuring means 11 or by inputting the value displayed on the magnification display 18 into the keyboard 31. This is done by inputting from .

In step S2, as shown in FIG. 4(a), the position data of each point on the XY coordinate axes of the data tablet 20, that is, the reference point PO drawn on the layout designation sheet B and the plate line H (the scanner's The coordinate values of the two points P1 and P2 on the top (corresponding to the reference line when pasting the original on the input drum),
Projected image! The coordinate values of vertices A1, B1, C1, and Dl of the rectangle forming the document outline in (the figure shows a projected image of the document corresponding to figure E3 shown in FIG. 16), the apex 11 of the cutout figure, and Jl , K1, and Ll, and the coordinate values of the specific point T1, which will be used later when positioning the image, are input.

Next, the first layout data creation means 30b creates first layout data based on the data input in steps S1 and B2 (B3).

The first layout data creation means 30b is shown in FIG. 4(a).
Calculate the inclination θ of the printing plate line H with respect to the X axis, which is determined from the coordinate values of points P1 and P2 shown in
1. From the coordinate values of Jl, K1, and Ll, the vertices El, Fl, of the rectangle indicating the trimming range as shown in FIG.
G1, calculate the old coordinate values, and as shown in Figure 4),
Each of the above points A1, Bl, C1, 01, El, Fl, in the xy coordinate system with the point PO as the origin and the printing plate line H as the reference line.
Points a1, bl, cl, dl, el, fl, gl, h corresponding to Gl, Hl, T1, Jl, Kl, LL, T1
Calculate the coordinate values of l, 11, jl, kl, 11 tl,
First layout data is created by associating these calculated coordinate values with the document size, separation size, scanner resolution, and magnification data input in steps S1 and B2. Next, the drawing data calculating means 30a calculates drawing data (B4).
Points a1, bl, cl, dl, el, f shown in Figure [Exist])
The coordinate values of l, gl, and hl are divided by the magnification value input in step S2.

Regarding the coordinate values of the trimming range, in the case of a cutout figure, the coordinate values of the figure indicating the trimming range are not input from the data tablet 20 and are calculated from the coordinate values of the cutout figure as described above. If the figure is not a cutout figure, such as figure E6 shown in FIG.

When the drawing data is calculated in this way, it is determined whether or not the measurement of the document is finished (G5). If it is not finished, the process returns to step S1, performs the process from step S1 on another document, and then ends the process. If so, output the first layout data created in step S3 (B6), and further,
The drawing data calculated in step S4 is output (S7
), based on this output drawing data, block-3
Step 4 draws the outline, trimming frame, etc. of each document on the sheet W. Note that the drawing position on the sheet W is determined automatically based on preset drawing parameters or according to instructions from the operator.

FIG. 5 is a schematic diagram showing the contents of the first layout data output in step S6 of FIG. 3, and each data is associated with the measured originals N111 to 9 as shown. Here, "outline", "cropping frame"
, "cutout" and "specific point" are the coordinate values of each point in the xy coordinate system as shown in FIG. The first layout data shown in FIG. 5 is recorded on the floppy FDI by the floppy disk drive 33.

Note that the position data of the "cutout" is not limited to position data representing a rectangle as shown in FIG. 5, but may be polygonal position data. By making the shape of the cutout polygonal, Cutout images closer to the object can be contained within one separation.

FIG. 6 is a schematic diagram of the sheet W created in block 34 based on the drawing data output in step S7 of FIG.
1 is drawn, and an outline 302 and a trimming frame 303 of each original are drawn at predetermined positions, and an original NCL 30ON and a magnification value 300m are drawn near these original outlines and trimming frames. Then, the operator pastes each original onto the sheet W along the original outline 302, sets the sheet W with the pasted original on the input drum 51 of the layout scanner 50, and sets the trimming frame 3
The image data input range, that is, the scan range of each document is set based on 03.

FIG. 7 is a schematic diagram showing the input surface 42 of the data tablet 41 provided in the copy mount information creation device f40.
As shown in the figure, a mount area 42a5, a first menu area 42b, and a second menu area 42c are set on the input surface 42. The mount area 42a is the layout designated paper B shown in FIG.
The settings are made by inputting three points, M1, M2, and A3, using a cursor (not shown) in accordance with the block copy mount created based on the above. In the first menu area 42b, graphics frequently used on the data tablet 41 are set as items. Here, rectangles, circles, polygons,
Straight line...− is defined as each item. 2nd menu area 4
2c includes layout items such as pattern number, magnification ratio (%), netting → rope %, Ikiki color, plate color, specific point, terminator, operational items for end point, C (cyan), Y (
Color items such as (yellow), M (magenta), and K (black) are set, and in these items, 0 to 9 for inputting numerical values, a decimal point, and TAB indicating the delimitation of numerical values are set.

Next, operations for inputting various position data and rape plate data on the data tablet 41 will be explained. In this case, the block mount is an accurate trace of the layout finalized for plate making based on the layout designation paper B, but for the sake of explanation, the layout designation paper B shown in Figure 16 is used as the block mount. do.

First, the plate surface coordinates, which are the coordinates of the mount area, are input. This is done by inputting the three points M1 to M3 shown in FIG. ``Print color'', ``C'', ``1'', ``0''
","Specify TABJ sequentially.

After inputting the plate color, input the figure.

The figures refer to figures indicating the trimming range and other figures drawn on the stencil mount. For example, if the figure is a rectangle like El, "
Rectangle” followed by figure I! Input the two vertices at the top left and bottom right of 1 using the cursor. This figure can be either a picture or a rope. In the case of a picture, the image data will be imported from the original, and in the case of halftone printing, it will be filled in with a specified color. In the case of netting, the color of the netting is input. Since the figure E1 is a rope hanger and its mesh percentage is cyan 100%, the input is "rope hanger",
"C", "1", "0", rQ,, rTABJ. In addition, in the case of figure E6, since it is a picture, the picture number, scaling factor (
To enter the pattern number (magnification) and specific point, click
Perform the operation ``Picture number'', ``4'', rTABJ (in the case of pattern number 4), and input the magnification rate as ``Variation rate J'', ``1''.
, r2'', rQ,, r'l'AB'' (when the magnification is 120%), and the specific point input follows ``Specific Point'' and points to a predetermined point on the copy board. The input is performed for the figure whose design is drawn on the block mount. In addition, the magnification measuring machine 10 has already been
If more specific points are input, the specific points are inputted twice, but for accuracy, the specific points input from the data tablet 41 are considered valid. Here, the above-mentioned pattern number is the same as the manuscript input manually in step S1 of FIG. 3, and input of the magnification ratio will be omitted if the magnification data is input in step S2 of FIG. 3. . Also, shapes E3, E4, E5, ET, E8, E9, ELL, El
In the case of a cutout figure such as 2, only the picture number and specific point are input without inputting the coordinate values of the figure indicating the trimming range. In addition, if there is a live rule that represents the ruled line that will actually be printed, input the color of the live rule.
Perform "M", "5", rQJ, rTABJ (in the case of Ikiki-iro M50%).

"Terminator" in the second menu area 42C is for returning to the starting point of the input operation, and by specifying "terminator" the above-described operation can be performed on a new figure. Furthermore, when "end" is instructed, data input from the data tablet 41 ends.

Then, based on the data inputted from the data tablet 41 in this way, the second layout data creation means 4
3a creates second layout data based on the block mount.

FIGS. 8(a) and 8(b) are schematic diagrams showing the contents of data created by the second layout data creation means 43a.

As shown in FIG. 8(a), the second layout data is “
It consists of "figure Nα", "figure shape", "type of figure", "flat screen information", "document level", "arrangement position", and "specific point".

Here, "figure Nα" is the figure E1, E2, E3, E4, E5, E6, E7, E8 on the layout designation sheet shown in FIG.
, E9, EIO, Ell, and E12, the "figure shape" is input from the first menu area 42b in FIG. 7, and the "figure type" is input from the first menu area 42b.
It is used to distinguish between regular shapes shown in the figure and other cutout figures, "flat dot information" indicates the dot percentage in the case of halftone dots, and "manuscript Nα" and "specific point" This corresponds to the "picture number" and "specific point" input from the second menu area 42c shown in the figure.

Further, "arrangement information" indicates the positional relationship of each figure input from the data tablet 41, as shown in FIG. 8(c). As shown in the figure, the mesh shapes El and E2
, E8 is given data on the figure shape and its position, and data on the figure shape, position and specific point are given to the regular figure E6, and the cutout figure [! 3.E

Next, the inputting of image data of a document in the layout scanner 50, the layout processing of the inputted image data, and the outputting of the layout-processed image data will be described.

FIG. 9 is a flowchart showing the control operation of the input/output computer 55, and FIG. 10 is a schematic diagram of a magnetic disk that stores input image data. Explain input. In this case, it is assumed that a predetermined original is pasted on a sheet W created by the scanner original pasting sheet creation device 1, that this sheet W is set in advance on the input drum 51, and that image data is input to the floppy FDI. This is performed based on the recorded first layout data.

First, read the first layout data from the floppy FDI set on the floppy disk 56.
), waits for the input size of the original for which image data is to be read (5L2), waits for the input size to be set (5L2), and waits for the input size to be set (5L2)
), the input of the original Nα is performed by the operator operating the console 57. The input size is input drum 51
mounted on.

The setting indicates the range in which the original scanning head scans the document, and is calculated from the trimming frame and magnification data written on the floppy FDI.The setting is determined by the operator indicating the scanning start point in the circumferential direction and axial direction of the input drum 51. It is done by doing. Here, the input size is easily set by specifying the scan start point of each vertex of the trimming frame drawn on the sheet W on the input drum 51. When this input size setting is completed, the image data calculation means 55a calculates the amount of image data (314
). The image data amount corresponds to the data amount in the magnetic disk 66 when image data obtained by scanning a document is stored in the magnetic disk 66, and is the input size input in step S13 and read out in step Sll. It is calculated from the scanner resolution in the first layout data.

Next, the system waits for input from the console 57 of the disk space for storing image data from the plurality of magnetic disks 66 (step 515), and when the disk space is input, the data storage area setting means 55b is specified in step 315. A data storage area for storing the image data calculated in step S14 is set in the magnetic disk (S
16). Setting of this data storage area is performed in step S15.
For example, as shown in FIG. In the case where Nαl is input in step S15, image data is already stored in the area IMI on the disk of Nfll.
- Assuming that the image data is stored in IM3, in step 316, an area IM4 is set to store the image data calculated in step S14.

Thereafter, after various scanner disassembly conditions are set, the input drum 51 is rotated and the scanner input of the document specified in step 312 is performed from the scanning head (not shown) (
317), captures the image data via the interface 53, and stores the image data in the area set in step S16 of the disk specified in step S15 (
818), and then it is determined whether to continue (S1
9) If the process is to be continued, the process returns to step S12 and the processes from step S12 onward are performed for the remaining documents; if the process is not to be continued, the process is terminated.

In this way, by inputting the image data of the manuscript necessary for the layout based on the first layout data from the scanner manuscript pasting sheet creation device 1, it is possible to scan the manuscript which takes time before the draft mount is completed. Input work can be done in advance.

Next, the control operation of the layout computer 60 will be explained in detail.

FIG. 11 is a flow chart showing the control operation of the separation layout data creating means 60a of the layout computer 60, and the process of creating the separation layout data will be described below based on the figure.

First, the first layout data recorded on the floppy FDI is read out via the floppy disk drive 61 (521), and then the second layout data recorded on the floppy FD2 is read out (S22).

Next, the document Nα is compared with the read first layout data and second layout data (S
23) For the verified manuscript Nα, determine the type of figure based on the second layout data shown in FIG. 8(a).52
4) If the type of figure is "Cutout", create figure data based on the cutout data of the first layout data shown in FIG. Figure data is created based on the fixed figure data of the second layout data shown in Figure (b) (326
).

The two types of graphic data created in this way and the eighth
"Flat mesh information" other than the data related to the figure shown in Figure (a)
New layout data is created by merging the "specific points" (327). Here, the position of the graphic data created in step 326 is determined as shown in FIG. It is necessary to perform positioning. This positioning is performed at specific points t1 to t9 shown in FIG. 5 and from 01 to ■ shown in FIG.
Next, it is determined whether or not to continue (32B), and if it is determined to continue, the process returns to step S23, and step S23 is performed for the remaining manuscripts. Subsequent processing is performed.

In this way, by repeating the data merging in step S27 for the manuscripts collated by the user in step S23, layout data for one entire page of printed material is created. The layout data is created in units of plate separations in the first layout data shown in FIG. Then, when data is merged in step S27 for all manuscripts in units of separations, rNoJ is determined in step 328, and step 3
The layout data for each color separation obtained by repeating the processes from step 23 to step 327 is outputted as layout data for color separation (S29), and is recorded on the floppy FD 3 via the floppy disk drive 61.

FIGS. 12A and 12B are schematic diagrams showing data created by the separation layout data creation means 60a as described above. In this case, FIG. 12(a) shows data regarding the separation block 1, and the separation data SEI is the cutout figure data LE3, Ll from the first layout data.
! 5. LH? , LH9 and LE12, and regular figure data LEI, LE2 and L from the second layout data.
It is composed of E6. Figure 12 et al.) show data regarding the separation stone 2, in which the separation data SE2 is cutout figure data from the first layout data E4,
It is composed of LE8 and LEII, and regular figure data LEIO from the second layout data. As shown in the figure, the graphic data of the separation data SEI and SE2 are associated with the data of the specific points U1 to u9 from the second layout data.

FIG. 13 is a flowchart showing the control operations of the image positioning means 60b and the makeup image data creation means 60c, and the makeup image creation process will be explained below based on the figure.

First, the layout data for separation is read out from the floppy FD 3 (531), and the image data of each document is read out from the storage disk 66 (332). Next, the image positioning means 60b positions the read image data according to the separation data shown in FIG. 12 (S33). Positioning of the image data is performed by displaying the image data read out in step S32 and the graphic data corresponding to this image data on the display 62 so that their center points coincide, and determining the position of the specific point displayed at the same time. This is done by determining the That is, if the relative position of the displayed image and the figure is correct, the position of the specific point at this time is taken as the image position; if it is incorrect, the position of the specific point is corrected by operating the pointing device 63, and the corrected specified point is The position of the point is taken as the position of the image. The image positioning data created by the image positioning means 60b in this manner is stored in the floppy FD 3 (334).

Thereafter, the makeup image data creation means 60c reads out the separation layout data and the positioning data determined in step S33, that is, the specific point data, from the floppy FD3, reads each image data from the magnetic disk 66, and reads out the image data from the floppy FD3. The read image data is trimmed and positioned based on the data, and a layout for one page of printed matter, that is, makeup processing is performed (S35), and this makeup image data is transferred to the magnetic disk 67 as makeup image data. (336). Here, step 33
Since the layout data for color separation read in step 1 is in units of color separations, the makeup image data stored in the magnetic disk 67 in step 336 is also in units of color separations.

FIGS. 14(a) and 14(b) are schematic diagrams showing the state of makeup image data stored in the magnetic disk 67. FIG. 14(a) shows the makeup image data for the separation Nα1, and as shown in the figure, the makeup image data Sll is connected to the rope image data MEI, MB2,
Photo image data ME3, MB2, MB2, ME'? ,
It is composed of MB9 and I'1E12.

Photo image data ME3, H[! 5, MB2, MB2, gate [! 9. MB12 transfers the image data of original Na, 1.3.4.5.7.9 stored in magnetic disk 66 to the first
The trimming position is determined based on data such as the figure LH3 and the specific point Ul shown in FIG. 2(a).

FIG. 14(b) shows makeup image data for separation Nα2, and as shown, the makeup image data 512 includes halftone image data MEIO, photographic image data ME4, MB2, ? It is composed of IE11. The photographic image data ME4, MB2, and MEII are obtained by trimming and positioning the image data of the original Nα2.6.8 stored in the magnetic disk 66 using data such as the figure LH4 and the specific point u2 shown in FIG. 12 0)). It is.

The makeup image data Sll, 512 in units of color separation stored in the magnetic disk 67 as described above is read out by the input/output computer 55, and the exposed film is set on the output drum 52 via the interface 54. is output above. As a result, the color separation unit yellow,
Magenta, cyan and black master plates are created.

Then, by combining the original plates of the created separation units, a new original plate for one page of printed matter is created, and based on this,
Printing will be performed through the printing plate process.

By the way, in the original plate of the separation unit created in this way, the part corresponding to the image data ME3 etc. shown in FIG. 14 includes a part other than the subject part to be actually printed. It is necessary to extract only This extraction of the subject portion is performed by creating a cutout mask along the outline of the subject, and superimposing this cutout mask and the original plate of the above-mentioned separation unit for photo synthesis.

(Effects of the Invention) As described above, in the present invention, the first layout data creation means includes the document number, document magnification data, image cutout data, and separation instruction data indicating the overlap of images to be laid out. the created first layout data is recorded on a first recording medium, and the image data input means inputs the input drum of the scanner based on the data recorded on the first recording medium. Since the image data of the set original is captured and stored in the first image data storage means, the original can be input into the scanner before the final specification format of the printed matter is determined, and the second layout data creation means Create second layout data including figure data consisting of the number of figures drawn on the lower mount and representative shapes indicating the cropping range of the image, and flat screen data, and use this created second layout data as the second layout data. Since it is recorded on a recording medium, accurate layout data can be created based on the block mount that shows the final specification appearance of the printed material. Then, the layout data reading means reads the layout data recorded on the first recording medium and the second recording medium, and based on the data read by the layout data reading means, the layout data creation means for separation is executed. The makeup image data creation means merges the first layout data and the second layout data to create layout data in units where the image data do not overlap, and based on the data created by the separation layout data creation means. reads the image data stored in the first image data storage means, performs trimming and positioning to create makeup image data, and the image data created by this makeup image data creation means is stored in the second image data storage means. The image data is stored in the image data storage means.

Thereafter, in order to create a plurality of master plates for one page of the printed matter from which the separation creating means outputs the image data stored in the second image data storage means, the image is displayed on a display and complicated cutting is performed. It is possible to obtain something close to the final original without any additional work, and as a result, most of the plate-making work for printed matter such as leaflets, which requires short delivery times, can be done by computer processing, and as a result, leaflets, etc. This has the effect of greatly improving the efficiency of plate-making work for printed matter.
