DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plate making system,
More particularly, the present invention relates to a plate making system for printing a building material having an abstract pattern.

[0002]

2. Description of the Related Art In recent years, the shortage of natural materials such as wood has been called out, and various building materials such as plywood and gypsum board have been developed as substitutes for such materials. As a result, the role played by building material printing has become important. There are two types of printing patterns for building materials: wood grain patterns that imitate natural wood patterns such as wood grain or stone grain, and abstract patterns related to human creation, such as geometric patterns, sand grain patterns, ground patterns, and floral patterns. However, since the present invention relates to the latter abstract pattern, plate making of the abstract pattern will be described below.

FIG. 12 schematically shows a conventional abstract pattern making process. As shown in FIG. 12A, first, when a material sample of an abstract pattern including a design image, a photograph, and the like is submitted, the material sample is photographed with a plate-making camera to create a separation film, and this is separated from an adjacent material. In order to eliminate the steps of the sample, the plates are successively printed and repeated by film synthesis while applying an appropriate mask to create a plate for proof printing (hereinafter, this plate is referred to as a baby plate). The film from which the material sample was taken is usually about 3 to 5 cm square, but as shown in FIG. 12B, the film 101 is repeated nine times each in the horizontal and vertical directions to create a plate 102 about 1 m square. can do. This is the version usually called the baby version. Next, gravure engraving is performed based on the baby plate, a printing plate for gravure printing is created and proof printing is performed, and when a desired abstract pattern is obtained, the baby plate is repeated and used for the main plate. A plate is created, a printing plate is created based on the plate, and proof printing is performed again. When a desired abstract pattern is obtained, printing is performed by this machine.

[0004] The above is a process for producing a baby plate by film synthesis, and all of the processes are manually performed by an operator. In recent years, a film scanner is used, for example, by photographing a material sample by using a layout scanner. Attempts have been made to digitize a part of the above process by performing the steps of reading the image data, repeating the image data, outputting the film as a film, and creating a baby plate with a layout scanner. However, also in this case, the step of repeating the baby version to create the main version is performed by manually combining the baby version photographically.

[0005]

However, as described above, in the past, the plate making process of printing a building material with an abstract pattern is usually performed manually, which is not only problematic in that it is extremely expensive. There were also the following problems.
In other words, the material sample may have uneven density or an uneven pattern. The unevenness of density and the unevenness of the pattern do not cause any problems in the material sample itself, but when a baby plate is created by repeating, the unevenness of the density or the unevenness of the pattern is emphasized and the creation is performed. It appears as a repetition pattern that is not intended by the creator or designer, and the repetition pattern is more prominent than the original abstract pattern, which is a major problem. Name). For example, as shown in FIG. 13A, it is assumed that density unevenness as indicated by 104 has occurred in a material sample 103 having a fine pattern (not shown), and as shown in FIG. If the baby plate 105 is created four times in the vertical direction and a baby plate 105 is created, a printing plate is created based on the baby plate 105, and when gravure printing is performed, the density unevenness is reduced as shown in FIG. The repetitive pattern is emphasized, resulting in a pattern. On the other hand, when joints are added as shown in FIG. D, the pattern is relatively inconspicuous because the lattice pattern of the joints is conspicuous. There is no problem.

As described above, since the occurrence of pattern distortion is a fatal defect for an abstract pattern building material, an operation for confirming the presence or absence of pattern distortion is performed in the middle of the process of printing this plate. Conventionally, means for confirming by proof printing has been adopted. Of course, it is conceivable to check the pattern on the plate making film, but since the pattern changes depending on the color, it is not possible to reliably grasp whether the pattern is black and white on the plate making film which is a black and white film. Very difficult,
In the end, although the cost was high, it had to be confirmed by proof printing using a baby version.

[0007] The work of removing the pattern is called a retouching operation. The mask is re-created, the pattern is rearranged, or the pattern is rotated to synthesize a film, and the baby is printed. The retouching work is performed, but the retouching work requires not only a great skill but also a large work load, and it takes a long time since all the work is performed manually, and as a result, it takes a long time until the delivery date Plate making cost was high. Moreover,
There are not many patterns that cannot be removed by manual retouching, and in such cases, the planning itself is canceled,
In some cases, plate making ends in vain.

[0008] Such a situation is the same when a layout scanner is used. Although the creation of a baby plate pattern is automated, the retouching operation still relies on manual work. Is something that has not been resolved. Of course, the pattern of the material sample read by the input scanner can be displayed on the monitor screen and rotated, or repeated using an appropriate mask pattern. The operation was the same as the operation, and instead of using an optical operation using a film, the operation was merely performed on a monitor using a pointing device such as a mouse or a stylus pen, and the time and effort were exactly the same. In addition, since the entire pattern of the baby plate having a size of about 1 m square cannot be displayed on the screen as described above, whether the pattern has been removed even if the retouching work is performed on the display screen. Could not be confirmed. In other words, it is not possible to know whether pattern habits will occur from the pattern of the material sample alone, but it is possible to confirm the occurrence of pattern habits only after repeating the material sample and creating a baby version, Therefore, in order to be able to confirm the presence or absence of the pattern, it is necessary to be able to display the entire baby plate pattern on the monitor screen, but the monitor of the conventional layout scanner cannot display it.

[0009] Furthermore, even if the entire pattern of the baby version can be displayed, even though the pattern cannot be confirmed with the baby version, the pattern will be lost when the baby version is repeated and the main version is created. In some cases, such a situation cannot be handled by a conventional abstract pattern plate making system using a layout scanner.

An object of the present invention is to solve the above-mentioned problems, and an object of the present invention is to provide an abstract pattern plate making system capable of removing a pattern in an abstract pattern and a printed material thereof.

[0011]

In order to achieve the above object, an abstract pattern making system according to the present invention converts pattern data of two randomly selected pattern areas in an endless pattern into a predetermined mask pattern. In the abstract pattern plate making system comprising a pattern removal device that removes pattern removal by replacing each other based on the pattern pattern, the pattern removal device includes a mask pattern protruding when the mask pattern protrudes from an endless pattern. The printed area of the endless pattern, the pattern data of two randomly selected pattern areas in the endless pattern are printed in a predetermined mask pattern. When the mask patterns protrude from the endless pattern when replacing each other based on the It is printed using a printing plate created based on a pattern obtained by repeating the endless pattern, which has been sent to the side opposite to the protruding side and has the habit removed, a predetermined number of times in the vertical and horizontal directions. And

[0012]

The abstract pattern making system of the present invention has a pattern removing means. The pattern removing means divides the endless pattern into blocks over the entire surface and applies a predetermined mask pattern to each block. At this time, if the mask pattern protrudes from the endless pattern, the area of the mask pattern protrudes. Is sent to the side opposite to the protruding side. The position where the protruding area of the mask pattern is sent is on the opposite side to the protruding side and opposite to the protruding position, or on the opposite side to the protruding side, and is one endless cycle of the protruding position. / 2 pitch shifted. The pattern removal unit performs pattern removal by replacing pattern data of two randomly selected pattern areas in the endless pattern with each other based on a predetermined mask pattern.

[0013]

Embodiments will be described below with reference to the drawings.
FIG. 1 is a diagram showing the configuration of an embodiment of an abstract pattern making system according to the present invention, wherein 1 is an input scanner, 2 is an output scanner, 3 is control means, 4 is input means, and 5 is storage means. , 6 is a gravure engraving machine, 7 is a color printer, 8 is an abstract pattern plate making means, 9 is an endless processing section, 11 is a pattern removal processing section, 12 is a repeat processing section, 13 is a display processing section, and 14 is a color processing section. Indicates a monitor.

First, the configuration of each section shown in FIG. 1 will be briefly described as follows. The input scanner 1 scans a color film obtained by photographing a material sample, decomposes each pixel into four colors of cyan (C), magenta (M), yellow (Y), and black (K). It is output as digital image data of a number, for example, 8 bits, and has the same configuration as the input scanner used in the conventional layout scanner. Output scanner 2
Is to output color separations of C, M, Y, and K on a film, and has the same configuration as an output scanner used in a conventional layout scanner. The control means 3 manages and controls the operation of the abstract pattern making system.
It consists of a microcomputer and its peripheral devices.

The input means 4 comprises an input device such as a keyboard and a pointing device. Storage means 5
Comprises a storage device such as a RAM and / or a hard disk. The gravure engraving machine 6 performs engraving of a baby version and engraving of a main version. Color printer 7
Is composed of a sublimation transfer printer, an ink jet printer, or the like, and is capable of outputting a color hard copy of at least the size of a baby plate, and more preferably a device capable of outputting a color hard copy of the size of the main plate.

The abstract pattern plate making means 8 comprises an endless processing section 9, a pattern removal processing section 11, and a repeat processing section 12.
including. The operation of each of these units will be described later. The display processing means 12 controls the display of the color monitor 14 and includes a video RAM having a predetermined capacity corresponding to the number of pixels of the color monitor 14. The color monitor 14 is constituted by a display device such as a color CRT, but is desirably one capable of displaying with high definition.

Next, the operation of the configuration shown in FIG. 1 will be described with reference to FIG. FIG. 2 is a flowchart showing an example of steps of plate making and printing when the abstract pattern making system having the configuration shown in FIG. 1 is used. First, when a unit material, which is the minimum unit for repeating the abstract pattern, is submitted, the unit material is set in the input scanner 1 and read (step S).
1). If the unit material is a film, it can be set in the input scanner 1 as it is. However, in the case of a design image other than a film, it is once photographed and read using a color film, or a plate Create a separation film by shooting with a camera and read it. The image data of the unit material thus read is stored in the storage unit 5.

Next, when the endless processing is instructed from the input means 4, the control means 3 activates the endless processing section 9 of the abstract pattern plate making processing means 8 to execute the endless processing (step S2). . Here, the endless process is a process in which masking processing is performed on a unit material, and the upper and lower adjacent unit materials are watermark-combined to increase the area by a factor of four or nine.
A process to create pattern data about twice the size (hereinafter, the pattern obtained by the endless processing is called an endless pattern). The image data for the baby version simply repeats the endless pattern data a predetermined number of times. Is created. That is, the endless pattern is located at an intermediate stage between the unit material and the baby version, and thus the workload of the operator can be significantly reduced. In other words, conventionally, a baby version was directly created by repeating a unit material while performing a mask process. However, as described above, the unit material is about 3 to 5 cm square, and the baby version is about 1 m square. Because of the size, it takes a great deal of time to create a baby version. On the other hand, for an endless pattern, mask processing is performed, but the unit material only needs to be synthesized at most nine times, and synthesis is performed automatically. It will be
Since the baby version simply repeats the endless pattern created in this way without performing mask processing, the work load is greatly reduced as compared with the related art.

Hereinafter, the details of the endless processing will be described with reference to FIG. Now, assuming that an instruction to create an endless pattern by combining the unit materials three times in the horizontal and vertical directions is given, the endless processing unit 9 combines the unit materials three times in the horizontal direction and three times in the vertical direction. At this time, FIG.
As shown in A, when performing the lateral synthesis performs superposition by the width of W _Y, when performing vertical synthesis W _T
, And the second row is horizontal W
Shift by _O. Then, the watermark synthesis in the proportions indicated by a region R ₂ in FIG. 3B is a transverse overlapping area and vertical overlap region. For example, taking the synthesis of a unit material 15 ₁ and the unit elements 15 ₂ as an example, although the handle region R ₁ in the unit material 15 ₁ in FIG. 3B is 100%, the region R ₂ in the unit material 15 ₁ of the handle is while linearly decreasing to 0%, the unit material 15 ₂ of the handle increases from 0% linearly to 100%, the handle region R ₃ in the unit material 15 ₂ is 100%. The same applies to the vertical composition.

The unit materials can be automatically synthesized as described above. However, when it is expected that a step will occur in the overlapping portion of the unit materials, or when a pattern having a relatively large area exists in the overlapping portion. When it is predicted that the pattern is destroyed by the composition, the above-described automatic composition is not appropriate. Therefore, in addition to the above-described mode of performing the automatic synthesis, the endless processing unit 9 also includes a mode in which a mask for synthesis can be arbitrarily set. In this mode, for example, as shown in FIG. , Two masks M ₁ and M ₂ are set in the overlapped area, and watermark synthesis can be performed in a region sandwiched between these two masks at a rate indicated by a region R ₂ in FIG. 3B. The same applies to the vertical direction. However, it is natural that a mask is separately set at the time of vertical composition.

The overlap width W _{Y in} the horizontal direction, the overlap width W _{T in} the vertical direction, and the shift amount W _O of the second stage may be determined in advance in the endless processing unit 9 as fixed values.
The setting may be made by the operator through the input means 4 each time. Also, the setting of the two mask patterns
For example, the pattern of the horizontal overlapping portion and the pattern of the vertical overlapping portion are displayed on the color monitor 14, and the mask line is traced with a mouse or a stylus pen on the screen, and the traced pattern data is masked. What is necessary is just to take in as pattern data. The mask set for the horizontal synthesis is used in common in the horizontal synthesis, and the mask set for the vertical synthesis is common in the vertical synthesis. Used.

When the synthesis of the unit materials is completed as described above, the endless processing section 9 displays the synthesis result on the screen of the color monitor 14. Therefore, for example, a unit material 15 arbitrary point P ₁ on ₁ located in the upper left corner (FIG. 3A) is assumed to be indicated, the endless processing unit 9, the unit material 15 ₃ located in the upper right corner of the synthetic pattern, unit material 15 ₇ located in the lower left corner, the unit material 15 ₉ located in the lower right corner, at each indicated point in the unit on the material P ₁ and P ₂ that have the same address, P _3, the synthesis pattern P ₄ A coordinate value is obtained, a rectangle defined by these four points P ₁ , P ₂ , P ₃ , and P ₄ is cut out, registered as an endless pattern, and stored in a predetermined area of the storage means 5.

The reason for performing such cutting is to prevent a step from occurring when a baby version is prepared. That is, the baby plate, as will be described later is created by simply repeating the endless pattern, by performing a cut as described above, both sides of the handle of a straight line connecting two points P ₁ and P ₂ in Figure 3A , because it is exactly the same as a straight line on both sides of the handle connecting two points P ₃ and P _4, is not able step is generated even repeat the endless pattern vertically. The same applies to the horizontal direction. This is why it is called an endless pattern.

The above is the processing of step S2 in FIG.
In this way, by creating a pattern located at an intermediate stage between the unit material called the endless pattern and the baby plate, the workload can be significantly reduced as compared with the related art.

After the endless processing is completed, it is next determined whether or not the endless pattern has a pattern (step S3). This determination is made, for example, by repeating the endless pattern data created as described above a predetermined number of times in the vertical and horizontal directions, and transferring the pattern data to the color printer 7.
And observing the color hard copy. If the occurrence of pattern distortion is not confirmed, data of the baby version is created (step S5), but if the occurrence of pattern distortion is confirmed, the pattern distortion is removed. For this purpose, the printing abstract pattern plate making system shown in FIG. 1 replaces a pattern located at a predetermined address of an endless pattern with a pattern located at another address based on a predetermined mask pattern (hereinafter referred to as scrambling). The system is provided with a pattern removal processing unit 11 that removes the pattern removal by using a method.

Hereinafter, the principle of pattern removal by the scramble method will be described. The scramble method is grainy,
This is a method suitable for removing a pattern of an abstract pattern having a fine pattern such as a tint block, and has a configuration shown in FIG. 4 and includes a display mode for simulating the removal of the pattern and a batch mode for actually removing the pattern. Have.

When the pattern removal processing unit 11 instructs the pattern removal processing by the input unit 4, the control unit 3 executes the processing.
, The scramble method display mode is first activated when the scramble pattern removal is instructed. The display mode is a mode for confirming by simulation whether or not the pattern removal can be satisfactorily removed by the pattern removal processing. First, the display mode is stored in the storage means 5 in order to end the simulation in a short time. The image data of the endless pattern is thinned out so that the number of pixels is about 2K pixels × 2K pixels or less, and the entire endless pattern is displayed on the color monitor 14.
The image data is expanded to the image memory 20 in a size that can be displayed on the screen, and sent to the display processing means 13 to be displayed on the color monitor 14. Then, the pixels of the endless pattern from which the image data has been thinned out have a predetermined size,
It is divided into blocks of size about 200 pixels x 200 pixels.

The random address generation section 21 is instructed by the input means 4 to execute the number of pixel replacements specified by the operator. By generating a random number, an address pair indicating two different pixel blocks is executed. It is generated for each pixel and sent to the pixel block transfer unit 22.

5A to 5E show the mask data section 23.
Various mask patterns are registered as shown in
The mask pattern having the shape specified by the input means 4 is called from the data and sent to the pixel block transfer unit 22. Then, the pixel block transfer unit 22 captures the pixel data of the blocks located at the address pair AD ₁ , AD ₂ of the pixel block generated by the random address generation unit 21, and the pixels in these blocks are processed by the mask data unit 23. Replacement is performed according to the generated mask shape, and writing is performed at the original address position. Thus, the inside of the block of the mask pattern of the address AD ₁ pixels within the mask pattern of the block address AD ₂ is written inside the mask of the block address AD ₁ of the mask pattern of the address AD ₂ blocks Pixels inside the pattern are written. The above operation is repeated for the instructed number of times. Now, for example, as shown in FIG. 6, it is assumed that the thinned endless pattern 30 is divided into 9 (horizontal) × 8 (vertical) blocks, and a mask pattern having the shape shown in FIG. 5A is selected. Then, assuming that the random address generation unit 21 generates the address pair of BL ₁ and BL ₂ as the _first replacement, the pixel block transfer unit 22 captures the pixels of the block having the address BL _{1 and} the block of BL ₂ , The pixels included in the circular mask are exchanged. Next, assuming that an address pair BL ₃ , BL ₄ is generated as the second replacement, the pixel block transfer unit 22 captures the pixels of the block having the address BL _{3 and} the block of BL ₄ and stores the pixels included in the circular mask. Replace Hereinafter, this operation is performed by the number of times of execution.

When the pixels in the block are replaced by the specified number of executions, the image data in the image memory 20 is sent to the display processing means 13 and displayed on the color monitor 14. This allows the operator to confirm whether or not the pattern has been removed on the color monitor 14. If the pattern has been removed, the display mode ends and the batch mode is executed. If not, the number of executions is subsequently input and the above operation is repeated. The above is the operation in the display mode. The number of executions and the mask shape data at the end of the display mode are stored in a predetermined file.

Next, the operation in the batch mode will be described. If the removal of the pattern is confirmed by the display mode, the batch mode is instructed. In the batch mode, the original endless pattern image data is written into the image memory 20 and the random address generation unit 2
1 and the mask data section 23 are loaded with the number of executions and the mask shape in the display mode, respectively. Then, as in the display mode described above, the pixel block transfer unit 22 divides the endless pattern data in the image memory 20 into blocks of a predetermined size, and stores the data in the block of the address pair generated by the random address generation unit 21. Are replaced with reference to the designated mask pattern. If the block size is the same between the display mode and the batch mode, the mask size used in both modes is the same,
If the sizes of the blocks are different, the pixel block transfer unit 22 detects the ratio of the block size in the display mode to the block size in the batch mode, and performs processing to reduce or enlarge the mask size by the ratio.

The principle of pattern removal by the scramble method has been described above.
When the circular mask shown in FIG. 7A is used, the edge of the endless pattern does not cover the mask as shown in FIG. FIG. 7 illustrates an extreme case, but when performing pattern removal by an actual scramble method, the edges of the endless pattern are adjacent when repeating at the time of making a baby version. Since this is an important part for maintaining the continuity of the pattern with the endless pattern, blocks may not be allocated to the edge of the endless pattern as shown in FIG. It is something to be done.

However, in such a case, when a baby plate is prepared by repeating the endless pattern as will be described later, the repetition of the pattern at the edge portion where the pattern processing is not performed becomes apparent. A new pattern may occur. Therefore, the pixel block transfer unit 22 performs the following processing in order to allocate a block also to the edge of the endless pattern. First, when dividing the endless pattern into blocks, the pixel block transfer unit 22 does not allocate the blocks from the edge as shown in FIG.
Now, assuming that the endless pattern is divided into 5 × 5 blocks, blocks are allocated shifted from the endless pattern 30 as shown by 31 in FIG. Performs the process of sending to the opposite side.

The details are as follows. 9A to 9F are prepared as a method of feeding a portion that protrudes from the endless pattern to the opposite side, and the operator instructs the input means 4 as appropriate as to which method to use. Has been made.

FIGS. 9A and 9B are diagrams showing one mode of feeding in the case where the block protrudes in the horizontal and vertical directions of the endless pattern 30, respectively. The protruding portions L and U shown by broken lines are shown by solid lines, respectively. It is sent to the corresponding position on the opposite side to the side protruding as indicated by the enclosed L and U.
FIG. 9C is a diagram showing one mode of feeding when the block protrudes in the vertical direction of the endless pattern 30, and a portion L shown by a broken line is shifted by の of the endless cycle, That is, it is sent to the side opposite to the protruding side. FIG. 9D is a diagram showing one mode of feeding when the block protrudes in the vertical direction of the endless pattern 30. The protruding portion indicated by the broken line is further divided into two regions of UL and UR, and these UL and UR are divided. Are shifted to the opposite side by a half of the endless period. FIG. 9E is a diagram showing one mode of feeding in the case where a portion protrudes at a corner portion. The protruding portion indicated by a broken line is further divided into three regions of UL, UR, and DR, and a region DR is provided.
And the region UL is sent to a corresponding position on the side opposite to the protruding side, and the region UR is sent to a diagonal position. FIG. 9F
Is a diagram showing one mode of feeding when the sheet runs over the corner portion, and the protruding portion shown by the broken line further includes U and DR.
Is divided into two regions, and the region U has an endless period of 1
The area DR is shifted to the opposite side by a distance of / 2, and the area DR is sent to the corresponding position on the opposite side to the protruding side.

The pixel block transfer section 22 sends a portion protruding from the endless pattern to the opposite side in accordance with a feed mode instructed by the operator, assigns blocks to the entire endless pattern, and assigns blocks to the blocks divided by the feed processing described above. The mask pattern is divided into blocks and assigned, and pixels are replaced. For example, it is now assumed that a circular mask pattern is adopted, and the feed mode of FIG. 9E is used for the protruding portion of the corner portion of the endless pattern, and the feed mode of FIGS. 9A and 9B is used for the protruding portion on the left side and the upper side, respectively. Then, the correspondence of the mask pattern to the endless pattern is as shown in FIG. In FIG. 10, the portions indicated by broken lines indicate portions where the mask pattern protrudes from the endless pattern. And FIG.
The image data of the mask region shown by M ₁ in the case of replacing the image data of the divided mask region M ₂₁ and M _22, the image memory the image data of the pixel block transfer unit 22 mask region M ₁ fetches from the corresponding address of 20, the synthesis takes in image data of the mask region M ₂₁ and M ₂₂ from the corresponding address in the image memory 20. Then, the combined image data is transferred to the address of the mask area M ₁ on the image memory 20 for overwriting, and the image data of the mask area M ₁ is further divided into two parts, and the mask areas M ₂₁ and M _{22 of the} image memory 20 are divided. To each address and overwrite.

By the above-described processing, it is possible to perform the pattern removal by the scramble method for all the regions of the endless pattern, so that the pattern removal can be satisfactorily removed.

The image data of the endless pattern from which the pattern has been removed is registered in a predetermined file in the storage means 5. Note that the capacity of the image memory 20 is such that when image data of an endless pattern is classified into four colors of Y, M, C, and K, one pixel of data of one color needs about 8 bits. In order to perform the above-described scramble processing for all colors, 8K × 8K × 8 × 4 (bit)
Degree is necessary.

In the above description, the case where only one mask pattern is used has been described. However, the mask pattern to be used may be changed for each replacement by generating a random number or the like. In addition, addresses of two mask patterns to be replaced without being blocked may be generated as described above. Further, in the above embodiment, the pixel replacement is displayed on the color monitor 14 after the instructed number of executions has been performed. However, the number of executions is not instructed, and the image is replaced every 100 pixel replacements, for example. The replacement operation may be forcibly stopped when the operator determines that the pattern has been removed. As described above, it is possible to automatically perform the pattern removal work that has been conventionally performed manually.

The above is the step S4 in FIG.
When the pattern is removed at the stage of the endless pattern, baby version data is created (step S5). Figure 12 for the baby version
As shown in B, the endless pattern is created by simply repeating it vertically and horizontally.
Is prepared. That is, when the creation of the baby version is instructed by the input means 4, the repeat processing unit 12 is activated, and repeats the image data of the endless pattern a predetermined number of times in the vertical and horizontal directions. As a method of repeating the endless pattern at this time, a mode in which the endless pattern is regularly repeated in the vertical and horizontal directions as shown in FIG. 11A, and a mode of one endless cycle for each line of the endless pattern as shown in FIG. A mode in which the repeat is performed by shifting by / 2 is prepared, and the operator is instructed from the input unit 4 in which mode to repeat. Incidentally, the right end of the right half of the image of the endless pattern E ₁ in FIG. 11B is what is sent to the opposite side as shown in the figure E _2.

The baby version data thus created is registered in the storage means 5.

When the creation of the baby version is completed, it is confirmed again whether or not a pattern has occurred at the stage of the baby version (step S6). In this case, the presence / absence of the pattern may be confirmed by thinning out the baby version data and displaying it on the color monitor 14, but the baby version is large and a presentation is made to the user. Therefore, the baby version data is supplied from the storage means 5 to the color hard copy 7 and hard copy is performed.

If the occurrence of pattern distortion is confirmed in step S6, the flow returns to step S4 to perform the pattern distortion removal described above. If no pattern distortion is detected, baby version data is output. (Step S7). There are two ways to output this baby version. One method is to directly supply the baby plate data to the gravure engraving machine 6 to directly produce a printing plate, and the other is to output the baby plate data to the output scanner 2 as a film and print the plate data via the film. How to create Which method is adopted is arbitrary.

After the baby printing plate is prepared as described above, next, proof printing is performed using the printing plate, and it is checked whether or not the pattern has occurred again (step S).
8). If the pattern has occurred, the process returns to step S1 to start over from reading a new unit material, or returns to step S4 to remove the pattern at the endless pattern stage. When returning to step S1, the steps up to that point are completely wasted, but the costs are reduced and the workload is reduced because the steps are automated compared to the prior art, so that the waste is minimized. Can be fastened.

If there is no occurrence of pattern distortion in the proof printing using the baby plate, this plate data is output (step S).
9). This is performed by arranging the baby version data in the vertical and horizontal directions by the repeat processing unit 12 a predetermined number of times, and the created main version data is registered in the storage means 5 and output. The output of the plate data may be directly supplied to the gravure engraving machine 6 to create the plate directly, or may be output to a film by the output scanner 2 and printed out through the film, similarly to the output of the baby plate data. May be created.

After outputting the plate data as described above, proof printing (step S10) is performed again. If the final check is received and the printing is acceptable, the main printing is performed using the plate (step S11). , The process ends. If it is confirmed that the pattern is proofed as a result of the proof printing, the process returns to step S1 or step S4 to start over.

Although one embodiment of the present invention has been described, the present invention is not limited to the above-described embodiment, and it will be apparent to those skilled in the art that various modifications are possible.
