Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a page data imposition device and a plate making device for imposing a plate when making a plate, and more particularly to a plate making device directly made from print data. It is suitable.

[0002]

2. Description of the Related Art Conventionally, a printing method has been known in which a printing plate is prepared using a plate-making film and printing is performed using this printing plate. The printing process of this printing method will be described with reference to FIG. In the figure, first, in the first step K1, print data is created page by page using a computer. Then, in the second step K2, a plate-making film is created based on this print data. When the print data is color data, the printed matter is expressed by using a plurality of colors, and thus a printing plate for each color is required. Therefore, it is necessary to create a plate-making film corresponding to the printing plate for each color. Cyan C, magenta M, yellow Y and black K are generally used as the types of the plate-making film. Therefore, the print data is color-separated into the above four colors on a computer, and each plate-making film is created by an exposure machine based on each data. Each plate-making film created in this way,
It is called a separation film. Further, fine dots called halftone dots are formed at equal intervals on the color separation film, and gradation is expressed by the size of the dots.

In the third step K3, the color separation film is put together in units of several pages for each color. This work is referred to as a stencil imposition work, and a stencil machine is known as an apparatus for automatically performing this. Next, in the fourth step K4, a printing plate is created. Specifically, a plate is prepared by superposing a separation film, which has been subjected to the plating plate surface finishing operation, on a plate coated with a photosensitive material, exposing and developing the plate.

In the fifth step K5, the printing plate thus prepared is mounted on the printing machine to perform printing. Here, the offset printing machine will be described with reference to FIG. 7. In the figure,
The first to fourth printing units YY, MM, CC, KK sequentially print each color of yellow Y, magenta M, cyan C, and black K. In the first printing unit YY, a printing plate is mounted on the surface of the plate cylinder Y1 to form a plate surface. First, when dampening water is applied to the printing plate, only the non-image area of the printing plate receives the water.
When printing ink is applied thereto, the printing ink adheres only to the image area due to the repulsion of water. Then, when the plate cylinder Y1 rotates in the direction of the arrow, the printing ink is printed on the rubber blanket cylinder Y2.
Is copied to After that, the sheet aa sent from the sheet feeding device A passes through the rubber blanket cylinder Y2 and the impression cylinder Y3, and at this time, the yellow Y is printed on the sheet aa. Also, in the second to fourth printing units MM, CC, KK, the first printing unit YY
Similarly, each color of magenta M, cyan C, and black K is printed, and the printing ends.

In this way, printing is performed through each of the printing steps K1 to K5, but in the final fifth step K5, printing is performed using dampening water, so that the sheet aa It will grow. Therefore, there is a problem in that the printing position shifts as it passes through the printing units YY, MM, CC, KK. This point will be described with reference to FIG. In the figure, the first
When printing with the plate T1 of the plate, the registration mark t indicating the reference position
The printing paper Q1 on which b1 is printed is used as the printing plate Tn for the nth plate.
When printing with, the printing paper Qn on which the register mark tbn is printed
Get. Here, the first printing plate T1 and the nth printing plate Tn have the same size, but the nth printing sheet Qn
Has grown due to the effects of dampening water. Therefore,
The register mark tbn printed on the nth plate does not match the register mark tb1 printed on the first plate and is printed inside. When the printing position is deviated as described above, the sharpness of the printed matter is impaired.

In the conventional printing method, in order to solve this problem, when carrying out the printing plate imposition in the third step K3,
Create a printing plate by shifting the position of the separation film for each color,
The print position was prevented from shifting.

[0007]

By the way, with the progress of digital technology, a CtP (Computer to Computer) for directly making a printing plate from printing data without using a plate-making film.
Plate-related technology is being developed. In this CtP, the print data is input to the plate output machine,
A laser beam modulated based on the print data is applied to a printing plate coated with a photosensitive material to expose it. Then, this is developed to create a printing plate for each color plate.

By the way, in the conventional printing method, a color separation film is prepared based on the print data, and the position deviation is eliminated by adjusting the position of the color separation film when the plate is imprinted. Therefore, the plate output machine does not have a function of operating the print data to shift the exposure position on the plate.
Therefore, the CtP that supplies the print data to the plate output machine
Was difficult to apply to offset printing.

The present invention has been made in view of the above circumstances, and a main object of the present invention is to provide a page data imposition apparatus and a plate making apparatus capable of imposing print data easily. .

BEST MODE FOR CARRYING OUT THE INVENTION

1. Configuration of Embodiment Hereinafter, a configuration of an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram of one embodiment of the present invention. In the figure, reference numeral 1 is a page data imposition apparatus, which generates output data DS in which the page arrangement for exposing each printing plate is adjusted. 2 is CEPS (Color Electron)
ic prepress System) and generates page data DP. The CEPS 2 is an image processing device centered on a computer and has a color scanner for capturing an image. The above-mentioned page data DP is data in which print data is in page units, and has a resolution necessary to create a printing plate. Further, 3 is a page design system, which generates page data DP similarly to CEPS2. As a language of the page data DP generated by the page design system 3, for example, a page description language such as Post Script of Adobe Systems Incorporated is used. Further, 4 is a printing plate output machine, which creates a printing plate for each plate based on the output data DS.

Next, the configuration of the page data imposition apparatus 1 will be described. A CPU 10 controls the operation of the entire page data imposition apparatus 1. Reference numeral 11 is a keyboard with which numbers, characters and the like are input. A mouse 12 is used to input an operation instruction. Thirteen
Is a main storage device including a memory and stores page data DP, various management data, and the like. A hard disk 14 stores a large amount of page data DP and the like. A monitor 15 displays an imposition instruction and an instruction registration screen for registering the instruction. Further, in the instruction registration screen, the GUI to be instructed by the mouse 12
Is displayed.

2. Operation of Embodiment Hereinafter, an operation of the embodiment of the present invention will be described with reference to the drawings. FIG. 2 is a flowchart showing the operation of the embodiment of the present invention. First, when the process starts,
The page data DP is supplied to the page data imposition apparatus 1 from the CEPS 2 or the page design system 3. The page data DP is temporarily stored in the main storage device 13 or the hard disk 14 under the control of the CPU 10.

Here, the page data DP generated by the CEPS 2 or the page design system 3 will be described with reference to FIG. As shown in the figure, the page data DP is configured by combining various data. 1
The work of arranging various data in a page is called plate collection, and the collected data becomes page data DP. The page data DP is composed of image data GD, character data MD and graphic data ZD.

First, the image data GD will be described.
When making a printed matter such as a catalog, it is necessary to appropriately arrange photographs and prices of the products to be posted on the printed matter. Therefore, a plurality of image files corresponding to various products are prepared in advance. Then, in the process of plate collection, a predetermined image file is read and used as an image material. Also, one image file consists of image material with a certain area, but there are cases where you want to use a part of it, so you can apply an image window to the image material and display the image material inside the image window. Sometimes used. Therefore, the image data GD has the following information. That is, the image file name for specifying the file, the shape of the image window, the page origin relative coordinates of the image window, the page origin relative coordinates of the image arrangement, and the image enlargement ratio. Further, since the image data GD is also applied to a color image, it is represented by yellow Y, magenta M, cyan C, and black K, or red R, green G, and blue B, and has the above information for each color. The page origin in this example is "0" in the lower left corner.

The character data MD has a character color (YMC
K value), typeface name, page origin relative coordinates, and other information. The graphic data ZD includes information such as shape, line type, line color (YMCK value), line width, end point processing method, filling method, filling color (YMCK value), and page origin relative coordinates.

Next, in step S2 shown in FIG.
The U10 reads the page data DP stored in the main storage device 13 or the hard disk 14 and decomposes it into page data PD corresponding to each color plate. In the following description, the decomposed page data PD is used as the separated page data B
Let's call it PD. In this example, since the Y plate, the M plate, the C plate, and the K plate are supported, the four separated page data BPs are used.
D is generated. This process will be described with reference to FIG. First, regarding the image data GD, YMCK
When represented by, the data is used, and when represented by RGB, it is converted into YMCK. Next, character data MD
Is decomposed using the YMCK value specified by the character color. Furthermore, the ZD of the graphic data is decomposed using the YMCK value specified by the line color and the fill color. The various data thus decomposed are collected for each of the Y, M, C, and K plates, and four color separation page data BPD are generated for the same page.

When step S2 is completed, the process proceeds to step S3 shown in FIG. 2, where necessary imposition layout of the separation plate page data BPD is performed according to the final plate size. Specifically, it is instructed which page is to be arranged in what direction and position on the printing plate. That is, basic imposition instruction data is created.

This point will be described with reference to FIG. FIG. 5 shows a plate imposition instruction / registration screen displayed on the monitor 15. In the figure, reference numeral 100 denotes an image display unit, which displays a simulation screen showing the plate position under a predetermined condition. Reference numeral 200 denotes a basic version information display section, which displays a color plate, a page, or the like to be impositioned. An imposition pattern list display unit 300 displays registered imposition patterns. Reference numeral 400 denotes an imposition setting display unit, which displays the plate size, page size, and the like. Further, reference numeral 500 denotes a fine adjustment information adjustment unit, which displays the amount of movement for each color with respect to the page of the basic plate that is the target of imposition. The fine adjustment information adjustment unit 500 is displayed when the fine adjustment unit 250 in the basic version information display unit 200 is clicked using the mouse 12. Therefore, it is not normally displayed on the monitor 15.

First, when the operator operates the keyboard 11 and the mouse 12 to input the plate size, that is, the width W and the height H of the plate, the input values are set.
It is displayed in the display frames 421 and 422 of 0. Next, when the page size, that is, the width W and the height H of the page is input, the input values are displayed in the display frames 431 and 432. When the number of pages to be imprinted on one plate is input, the input value is displayed in the display frame 440. When "4" is displayed in the display frame 440 as in this example, 1
Imposition of 4 pages is performed for each plate.

When the above input is made, a simulation screen showing the plate position is displayed on the print image display section 110. That is, the page portions 111 to 114 arranged in the printing plate 110 are displayed.

Next, it is specified which page is to be arranged in each page section 111 to 114. Therefore, when the target page portion is specified with the mouse 12 and the page number is input using the keyboard 11, the page number is displayed in the display frame 220 and the page number is displayed in the page portion. After that, in order to specify the layout direction of the page, the target page portion is specified by the mouse 12, and the layout direction is input by the keyboard 11, and the layout direction is displayed in the display frame 230. In this example, the fourth page is arranged upside down in the page section 112. The page number displayed in the page portion is represented by a number that is rotated according to the arrangement direction of the page arranged therein.

After that, the arrangement positions of the page parts 111 to 114 in the plate 110 are specified. When the target page portion is specified with the mouse 12 and the coordinate value of the lower left corner of the plate portion is input using the keyboard 11 with the plate origin as the reference, the X and Y coordinate values are displayed in the display frames 241 and 242. It The plate origin is usually located in the lower left corner of the plate. In this example, the page portion 112 has a width X of 3 with respect to the plate origin.
It will be arranged at 48.00 mm and height Y of 152.00 mm. When the operator uses the keyboard 11 to input the coordinate value of the lower left corner of the page portion with reference to the plate origin, there is a possibility that the operator will enter an arrangement position that cannot be arranged due to the plate size. Therefore, after specifying the arrangement position, the plate size and each page portion 111 to 114
When performing imposition based on the arrangement position, etc., it is checked whether or not there is a designation that should not be actually made by comparing with the preset specified value. If there is an input error described above, the operator is informed of the input error on the plate imposition instruction and registration screen displayed on the monitor 15.

Finally, the basic page parts 111 to 1
Whether or not to define fine adjustment information (correction instruction) in consideration of the deviation of the printing position due to each color plate with respect to the arrangement position (basic imposition instruction data) of the basic plate that specifies the arrangement position in 14 printing plates 110 Or select. When selecting whether or not to define this fine adjustment information, when the fine adjustment section 250 displayed on the basic version information display section 20 is clicked, the fine adjustment information display section 500 is displayed. As the initial values displayed in the display frames 511 to 518, it is displayed that the moving amounts of X and Y are 0.00 mm assuming that the basic plate is not arranged. When “4” is displayed in the display frame 220 as in this example, fine adjustment is performed on four pages.

Next, in order to specify the fine adjustment position in consideration of the deviation of the printing position due to each color plate, the target color plate portion is specified by the mouse 12, and the fine adjustment information for the arrangement position defined in the basic plate is specified. For example, when the amount of movement is input with the keyboard 11, the amounts are displayed in the display frames 511 to 518. In addition,
When inputting the fine adjustment position using the keyboard 11,
In the same way as above, it is checked whether imposition is prohibited, and if there is an input error, the monitor 15
Notify the operator that there was an input error on the plate imposition instruction / registration screen displayed on the screen. Finally, it is selected whether to set the input fine adjustment information. To set fine adjustment information, click the setting unit 520 with the mouse 12.

After the imposition instruction is input in this way, the process proceeds to step s31 to select whether or not to register the current page imposition instruction. When registering, display frame 4
10 is specified with the mouse 12, and the imposition pattern name is input using the keyboard 11. After that, when the registration section 450 is clicked with the mouse 12 (step s4), the imposition pattern data representing the imposition instruction described above is stored in the main storage device 13 or the hard disk 14 together with the imposition pattern name. Therefore, the main storage device 13 or the hard disk 14 functions as a storage unit for imposition pattern data. Further, the imposition pattern name is newly displayed on the pattern list display unit 310. On the other hand, if the registration is not performed, no special operation is performed.

After the imposition instruction is input in this way, the process proceeds to step S31 to select whether or not to register the current page imposition instruction. When registering, display frame 4
10 is specified with the mouse 12, and the imposition pattern name is input using the keyboard 11. After that, when the registration section 450 is clicked with the mouse 12 (step S4), the imposition pattern name and the imposition pattern data representing the imposition instruction are stored in the main storage device 13 or the hard disk 14. Therefore, the main storage device 13 or the hard disk 14 functions as a storage unit for the imposition pattern data. Further, the pattern list display unit 310 newly displays the imposition pattern name. On the other hand, if the registration is not performed, no special operation is performed.

Next, it is selected whether or not to read the registered imposition pattern (step S41). When reading a registered imposition pattern, the pattern list display unit 3
The imposition pattern name displayed in 10 is clicked with the mouse 12, and then the calling unit 320 is clicked (step S5). Then, the CPU 10 accesses the main storage device 13 or the hard disk 14, reads the imposition pattern data corresponding to this imposition pattern name, and displays the plate imposition instruction / registration screen based on this. If the reading is to be stopped after clicking the imposition pattern name with the mouse 12, the cancel unit 330 may be clicked with the mouse 12. In this manner, by reading the registered imposition pattern data, the imposition instruction input operation can be omitted. On the other hand, when the imposition pattern is not read, no special operation is performed.

After that, when the execution section 600 is clicked with the mouse 12, the separated page data BDP corresponding to each page number arranged in the page sections 111 to 114 is read from the main storage device 13 or the hard disk 14, and Based on the plate page data BDP and the imposition instruction displayed on the plate imposition instruction / registration screen, the output data DS is generated and stored in the main storage device 13 or the hard disk 14 (step S6). The format of the output data DS is a data format having separate imposition pattern data and color separation page data, and one data for the entire printing plate whose page position has been adjusted in consideration of the imposition pattern data. And the data format. Since which data format is used for output depends on the type of the plate output device 4 in the subsequent stage, selective output is possible.

When the keyboard 11 is operated to input an output instruction to the plate output device 4, the page data imposition device 1 supplies the output data DS to the plate output device 4,
A printing plate is created based on this (step S
7). That is, the laser light modulated based on the output data is irradiated onto the printing plate coated with the photosensitive material to expose it,
Then, this is developed to create a printing plate for each color plate. Since the output data DS is obtained by adjusting the page position in the printing plate, it is possible to create a printing plate in which the deviation of the printing position due to each color plate is taken into consideration in advance. For example, in the offset printing machine shown in FIG. 7, if the black K printing performed in the fourth printing unit KK is printed outside 0.3 mm due to the effect of dampening water, create a printing plate to be used there. The output data DS for performing the printing can be generated so as to correspond to this condition, and the deviation of the printing position can be eliminated. As a result, CtP
Can be applied to offset printing.

3. Modifications The present invention is not limited to the above-described embodiments, and various modifications are possible, for example, as follows.

In the above embodiment, the calling of the registered page imposition instruction shown in FIG. 2 (step S41) need not be performed after the registration of the current page imposition instruction (steps S31, 4). That is, when the page imposition instruction is issued (step S3), the page imposition instruction is called,
Based on the called pattern data, a page imposition instruction may be made by changing the pattern data.

In the above embodiment, additional information such as a comment may be stored together with the pattern name. In this case, printing conditions such as the type of printing machine, the type of printing paper, and the type of printing ink can be stored. Therefore, it is possible to give a page imposition instruction using these additional information. Specifically, when various printing conditions are input, the registered imposition pattern closest to these conditions can be read out and changed to give a new imposition instruction.

In the above embodiment, the color plate is YMCK
Although a plate is used, a special color such as gold and silver may be added to this.

In the above embodiment, the page data imposition device 1 outputs the output data D whose page imposition position is adjusted.
By generating S, the printing position deviation due to the expansion of the printing paper in offset printing is eliminated. However, the present invention is not limited to this, and can be applied to any purpose for eliminating the printing position deviation, for example, the printing position deviation due to the mechanical error of the printing machine.

In the above embodiment, the output of the output data DS between the page data imposition apparatus 1 and the plate output machine 4 may be offline. In this case, if the output data DS generated by the page data imposition device 1 is recorded on an information recording medium such as a magneto-optical disk and the information recording medium is reproduced by the plate output device 4, the output data DS can be obtained. good. The plate output machine may have the function of the page data imposition device 1.
