Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an endless plate-making system suitable for printing building materials.

[0002]

2. Description of the Related Art Conventionally, building material printing has been performed as a method of applying makeup and protecting the surface of building materials. This printing of building materials is made of titanium paper, polyvinyl chloride, etc. that are pasted on the surface of building materials made of various types of glyphs and gypsum boards, and mainly endless patterns such as woodgrain patterns and abstract patterns. It is printed with ink for building materials according to.

The building material printing described above is usually performed by a gravure plate making method using a printing plate as shown in FIG. FIG.
The printing plate shown in (a) is of a conventional type that gives a shade according to a change in cell depth.
The printing plate shown in (b) is an electronic engraving type gravure engraving apparatus using a diamond needle, a laser or the like that operates in response to an electric signal. Here, the outline of the plate making process by the gravure plate making method will be described with reference to FIG. First, when a design original such as a design image or a photograph (here, an abstract pattern) is submitted, the design original is photographed by a plate making camera to create a disassembled film (separated into four colors).

Next, an appropriate mask is applied to the prepared disassembled plate film, and as shown in FIG. 16, it is converted into 3 × 3 by film composition (hereinafter referred to as “repeat”), and the 3 × 3. The endless plate is cut out from the plate and the endless plate is repeated vertically and horizontally to make a plate for proof printing (hereinafter referred to as a baby plate). Usually, in the seam part of the 3 × 3 plate, the seam of the two films is erased by using the blur effect of the diffuser.

Next, gravure engraving is performed based on the baby plate to prepare a proof printing plate for proof printing. When a desired abstract pattern is obtained with this proof printing plate, the baby plate is repeated to create the main plate. Then, gravure engraving is performed based on the printing plate to produce, for example, a printing plate for the printing plate shown in FIG. 13A or 13B. Proof printing is performed using this printing plate for a printing plate, and when the desired result is obtained, printing is performed with this printing plate.

The above-mentioned plate making process is usually carried out manually, but in recent years, attempts have been made to digitize a part of the above process using a layout scanner (described later). This layout scanner scans a film on which a picture original is photographed, edits image data corresponding to the film on a monitor, and outputs the edited data to the film. In that case, the seam portion of the 3 × 3 plate is overlapped by the watermark composition which is a unique function of the layout scanner. According to this method, it is possible to carry out the plate making work of a fine abstract pattern such as a grain pattern or a tint block without trouble. The baby plate thus created is manually repeated to create the present version. Gravure engraving is performed on the plate to prepare a plate for the plate as shown in FIG. 13 (a) or 13 (b).

However, in the above-mentioned conventional plate making process, "density unevenness" occurs in the pattern original,
If the pattern of the pattern document has "bias", these "density unevenness" and "bias" may be emphasized in a baby plate of about 1 m square created by repeating the pattern document.

FIG. 15 (b) shows a baby plate made from the pattern original shown in FIG. 15 (a). Figure 15
An abstract pattern of sand is drawn on the picture original of (a), and the point group P is darker than the other points. As shown in these figures, the point group P, which is not so noticeable in the design original,
In the baby plate of FIG. 15 (b), a repeating pattern extending obliquely (hereinafter, referred to as "pattern") is formed. In this way, the habit of patterning is more noticeable than the original pattern, and the appearance may be significantly impaired.

In the printing of a building material with an abstract pattern, the occurrence of pattern habit becomes a very serious problem. Therefore, as described above, the proof printing using the proof printing plate and the lithographic printing plate was used to confirm the presence or absence of the pattern habit. For this reason, it is necessary to create or recreate the proofing plate and the printing plate for the present plate, which causes a problem of high cost.

Further, in the proof printing, when a pattern habit has occurred, a retouching work for removing the pattern habit is performed. The retouching operation is an operation of recreating a mask, repositioning a pattern, rotating, etc., and recreating a baby plate or a book plate by film synthesis, which is performed manually. Since this retouching work requires a great deal of skill, there is a problem that the load on the worker is large and the working time is long.

In addition, in the manual retouching work,
Occasionally there is a pattern that cannot be removed. in this case,
There is a problem that the building material printing may be abandoned and the plate making process may be wasted. The above-mentioned various problems similarly occur in the plate making process using the layout scanner. The layout scanner replaces the optical work using the film with the operation on the monitor using the pointing device, etc., and the instructions of the work (relocation, rotation, etc.) to be performed in order to remove the pattern habit are It is done by workers. That is, the labor required for the retouching work is almost the same as that of the manual work.

[0012] Further, when an article having a certain size, such as a stone pattern or a flower pattern, is randomly arranged, a diffuser blurring effect at the seam portion or a method of using watermark composition is applied to the abstract pattern. There is a case where the watermark composite part of the item intersects with the article. In this case, a grid pattern along the seam is formed on this plate. That is, there is a problem that it can be applied only to an extremely limited abstract pattern.

Furthermore, according to the watermark composition, even in the case of a fine abstract pattern such as a grain pattern or a tint block, the joint portion is blurred like a band. This "striped blur" is a fine abstract pattern.
It is invisible but definitely present. Therefore, if you make a baby version by repeating the endless version with "band-shaped blur" up, down, left and right, the "band-shaped blur" will be continuous and a grid band will be generated, and this grid band will be recognized as a pattern. There is also the drawback that it will be done.

Therefore, the applicant has proposed an endless plate-making system described below. The endless plate-making system is a layout scanner system (described later).
It is composed of This layout scanner system scans a film on which a picture original is photographed and stores picture information corresponding to the film. And the operator
The layout scanner system is operated to edit and process the above pattern information.

The outline of the endless plate-making system will be described below. First, the image shown in FIG. 17A is displayed on the monitor of the layout scanner system. The operator
The layout scanner system is operated according to the displayed image to move the rectangle 27, and the four sides of the rectangle 27 are set as a free straight line or a free straight line composed of a plurality of line segments so that the four sides do not intersect with the article in the pattern 28. It is composed of a curve (see FIG. 17B). At this time, the left and right sides and the upper and lower sides of the rectangle 27 are free straight lines or free curved lines of the same shape so that they can be fitted together. The pattern 29 corresponding to the position and shape of the rectangle 27 created in this way is cut out.

Then, the cut-out patterns 29 are sown one after another (hereinafter referred to as "repeat") and fitted to each other.
As shown in (c), a 3 × 3 base is created. Then, the rectangle 30 displayed on the base is moved, and the rectangle 30 is fixed at a position where the patterns corresponding to the left and right sides and the upper and lower sides are continuous. Then, the base portion corresponding to the rectangle 30 is cut out to create an endless plate. This endless version simply repeats to create a seamless (endless) pattern.

The endless plate thus produced is repeated a predetermined number of times in the vertical and horizontal directions to form a baby plate. And
A proof printing plate corresponding to the baby plate is created, and proof printing is performed using this printing plate. In this proof printing, when it is confirmed that the pattern habit is generated due to the repetition of the same pattern, the endless plate is repeated using another repeat pattern of the layout scanner.

Several kinds of repeat patterns are prepared, and the baby plate is recreated using various kinds of repeat patterns until the pattern habit due to repetition is removed. If the pattern is not confirmed through such trial and error, the data of the endless plate or the baby plate is supplied to the gravure engraving device and repeated to prepare the plate.

[0019]

As described above, in the conventional endless plate making system, at the stage when the baby plate is made, the proofing plate is made based on the selected repeat pattern, and the printing is actually performed. Then, it was determined whether there was a pattern. For this reason, if a pattern habit is confirmed from the printing result, it is necessary to recreate the baby plate and the proof printing plate based on another repeat pattern. Therefore, there is a drawback that the working efficiency is lowered and the cost is increased because an expensive proof printing plate is recreated.

In order to alleviate these drawbacks, it is possible to reduce the size of the baby image and display it on the monitor of the layout scanner to determine the presence or absence of the pattern. However,
Conventionally, the endless version is simply repeated a certain number of times up, down, left, and right, so it is extremely easy to cause patterning, and there is no problem in the endless version itself, and it is possible to erase the pattern by simply changing the repeat pattern. Even then, there is a problem that an endless version that does not need to be corrected based on a wrong judgment is recreated, resulting in unnecessary work.

Further, since the image on the monitor is reduced in size, the image is rough and a large and conspicuous pattern can be confirmed.
There is a problem that it is not possible to confirm the pattern habit due to the repetition of fine points, and it is also impossible to confirm the pattern habit due to "a factor other than repetition" due to the shade of the pattern. For this reason, there is a possibility that an endless version that does not need to be modified may be recreated or that the repeat pattern that should be modified may not be modified based on a wrong judgment.

For these reasons, there is a demand for a plate making system which is low in cost, can easily eliminate patterning due to repetition, and can prevent erroneous operation due to erroneous judgment.
The present invention has been made in view of the above-mentioned circumstances, and an object of the present invention is to provide an endless plate-making system capable of easily eliminating pattern habits caused by repetition and preventing erroneous judgments.

[0023]

An endless plate-making system according to the present invention combines storage means for storing design information obtained by scanning a design original and design information stored in the storage means vertically and horizontally. Endless version information creating means for creating endless version information from a combination, expansion pattern storage means for storing a plurality of expansion patterns for expanding the endless version information created by the endless version information creating means to a baby version, and the expansion pattern storage It is characterized by further comprising: a copying and developing means for copying and developing the endless version information according to a developing pattern selected from the means and outputting the copying and developing information.

[0024]

According to the above construction, the endless version information creating means combines the pattern information stored in the storage device vertically and horizontally and creates the endless version information from the combination. Then, the copy expansion means performs the copy expansion of the endless version information according to the expansion pattern stored in the expansion pattern storage means, and outputs the copy expansion information. Since the expansion pattern storage means stores a plurality of expansion patterns, by changing the expansion pattern to be selected, the pattern habit due to repetition can be easily eliminated and erroneous judgment can be prevented.

[0025]

The input scanner 3 separates the scanned film into four colors based on the read color information and gradation information of each pixel. Specifically, the color of each pixel of the film to be scanned is changed to four colors of cyan (C), magenta (M), yellow (Y), and black (K) based on the information from the three primary color elements of the CCD. The image information (pattern information), which is decomposed and includes gradation information for each color, is supplied to the storage device 10. The input scanner 3 is not limited to the flat bed type scanner, and may be a drum type scanner generally used in plate making.

The processing unit 8 is installed in, for example, the base 100 (see FIG. 2), and includes a CPU, RO (not shown).
It is composed of M, RAM and various I / O interfaces. The processing device 8 performs various arithmetic processing on image information supplied from the input scanner 3 based on input data supplied from an input device 9 (described later), and image data obtained as a result of the arithmetic operation, Outputs engraving data, print data, decomposed data, display data, etc. Details of these arithmetic processes and data will be described later.

In FIG. 1, the input device 9 is provided, for example, on the base 100 (see FIG. 2) of the layout scanner system 2. The input device 9 is composed of a keyboard, a tablet, and the like, and supplies input data according to the operation of the operator to the processing device 8. The storage device 10 is, for example, a table 10.
0 (see FIG. 2) and stores reference dimension data of various figures, repeat pattern (expansion pattern) information, copy expansion area information, image data supplied from the processing device 8, and the like. When the amount of information is large, the processing device 8 and the storage device 10 are often installed as external units outside the table 100.

The color printer 15 outputs the print data supplied from the processing device 8 in color by a method such as ink jet, electrostatic printing, thermal transfer, and sublimation transfer. At that time, if the color printer 15 has a format conversion function and the image data can be converted into an outputtable format, the image data is supplied from the processing device 8. Output scanner 16
Depending on the decomposed version data supplied from the processing device 8,
Create separate film of each color of C, M, Y, K. At that time, the output scanner 16 has a format conversion function,
When the image data can be converted into an outputtable format, the image data is supplied from the processing device 8. Reference numeral 17 denotes a monitor including, for example, a color CRT (cathode-ray tube) or the like, which displays an image according to the display data supplied from the processing device 8.

Reference numeral 11 denotes a gravure engraving device, which is installed independently of the layout scanner system 2 as shown in FIG. In the gravure engraving apparatus 11, 12 is a substantially cylindrical gravure cylinder that is rotatably attached to the machine base 5, 13 is an engraving head carrier that is slidable in the longitudinal direction of the cylinder 12, and 14 is an engraving head that is attached to the carrier 13. Yes, it has engraving needles made of diamond or the like.

The gravure engraving device 11 moves the cylinder 12 and the carrier 13 based on the engraving data supplied from the processing device 8 online or via a recording medium such as a floppy disk, and the engraving head 14
Is operated to gravure-engrave a proofing plate or a printing plate for the plate on the surface of the cylinder 12. Gravure engraving device 11
In addition to the engraving data supplied from the processing device 8, the engraving can be performed based on the decomposed film output from the output scanner 16. In that case, the disassembled film is attached to the substantially cylindrical original set drum 4 which is rotatably attached to the machine table 5, and the original set drum 4 is attached.
Scanning head carrier 6 slidable in the longitudinal direction of the
It is scanned by an input scanning head 7 attached to the. Engraving is performed based on this scan data.

Referring again to FIG. 1, the image information supplied from the input scanner 3 is temporarily stored in the storage device 10.
When performing the endless plate-making work described later, the processing device 8
Calls the image information from the storage device 10, creates the rough image data by thinning the pixel density to 1 / n (n ≧ 2, n is a natural number), and stores it in the storage device 10. Further, the processing device 8 performs a calculation on the rough image data based on the input data, and supplies the rough image data of the calculation result to the monitor 17 to display it.

The input data input from the input device 9 is
Recalling and storing various information such as image information, rough image data, reference dimension data, etc. from the storage device 10, editing processing such as repeat, mask processing, cutout processing, etc. from image information to engraving data, decomposed data, print data The input data itself is sequentially stored in the storage device 10.

When the calculation based on a plurality of input data for the rough image data is completed and the desired image obtained is output, the processing device 8 converts the image data into engraving data, decomposed data and print data as necessary. The format is converted and supplied to the engraving device 11, the output scanner 16, and the color printing machine 15. If the engraving device 11, the output scanner 16, and the color printer 15 themselves have a format conversion function, the image data is directly supplied.

The processing performed by the processing device 8 having such a configuration will be described with reference to FIGS. 4 and 5.
FIG. 4 and FIG. 5 are flowcharts showing an example of a plate making process when the endless plate making system 1 is applied. The process in this flowchart is performed by the operator or the processing device 8.
Done by. It should be noted that the processing device 8 executes subsequent processes when predetermined input data is supplied from the input device 9.

In FIG. 4, first, when a power switch (not shown) is turned on, the processor 8 executes the operation program stored in the ROM. Then, the storage device 10 becomes ready to receive the image information from the input scanner 3, the worker sets the pattern information at a predetermined position of the input scanner 3, and instructs the input scanner 3 to start scanning, and the input scanner 3 Scans the pattern original and supplies the image information to the storage device 10. As a result, the image information input in step S1 is executed. The data structure of the image information stored in the storage device 10 is configured so that the gradation of each pixel is represented by 8 bits for each color (C, M, Y, K).

Next, in step S2, the processing device 8
Rough image data is created by thinning out the pixel density of the image data of each color to 1 / n, and each rough image data is stored in the storage device 10 in association with each image data. Also, the processing device 8
Supplies the display data corresponding to the rough image data to the monitor 17. As a result, the simple pattern 19 with rough pixels (see FIG. 6A) is displayed on the monitor 17.

Next, in step S3, the processing device 8 creates a rectangle 18. The rectangle 18 created here is shown in FIG.
As shown in (a), it is displayed on the monitor 17. The processing device 8 has VRAMs (not shown) for several screens and is configured to supply display data corresponding to each screen to the monitor 17. Further, since the monitor 17 simultaneously displays each of the supplied display data in accordance with the priority order, the simple pattern 19 is displayed in the VRAM corresponding to the lower layer screen.
When the rectangle 18 is written in the VRAM corresponding to the upper layer screen, the rectangle 18 is displayed with priority over the simple pattern 19 as shown in FIG. Here, the size of the rectangle 18 opened in the mask is determined by reference dimension data described later.

Next, in step S4 of FIG. 4, the operator operates the input device 9 to move only the rectangle 18. When the input data is supplied from the input device 9, the processing device 8 calculates the moving coordinates of the rectangle 18 according to the data and recreates the rectangle 18 at the calculated coordinates. Of course, it is assumed that the rectangle 18 before the coordinate calculation is deleted. When the display data corresponding to the recreated rectangle 18 is supplied to the monitor 17, the rectangle 18 moved according to the operation of the operator is displayed on the monitor 17. The operator continuously performs such an operation to move the rectangle 18 to a position having an appropriate pattern.

Next, in step S5, an endless plate cutting process is performed. Hereinafter, the endless plate cutting process will be described with reference to FIG. First, step SA1
Then, the operator operates the input device 9, and the left side 1 of the rectangle 18
8a (see FIG. 6B) is determined. The left side 18a is a combination of line segments (hereinafter referred to as a free straight line or a free curved line) that avoids the article in the simple pattern 19.

This free straight line is determined by, for example, a method of providing a plurality of passing points at positions avoiding articles and calculating the equation of the free straight line passing through these passing points (since the free curved line is also the same. , And the description thereof will be omitted hereinafter). Further, as shown in FIG. 6B, the right side 18b has the same shape as the left side 18a. This processing is performed, for example, by erasing the straight right side 18b and making the free straight line duplicated from the left side 18a the right side 18b.

Next, in step SA2, the rectangle 18 is moved as necessary so that the sides 18a and 18b do not intersect the article in the simple pattern 19. Specifically, the operator operates the input device 9 while referring to the monitor 17 to change the coordinates of the rectangle 18. And each side 18
a and 18b do not intersect with the article of the simple pattern 19,
The monitor 17 confirms and ends the moving operation.

Subsequent steps SA3 and SA4 are processes each having substantially the same steps as the above-mentioned steps SA1 and SA2, and as shown in FIG.
The upper side 18c and the lower side 18d are determined. And
If necessary, the operator moves the rectangle 18 so that each side 18a, 18b, 18c, 18d does not intersect the article of the simple pattern 19. For the procedure for determining the sides 18c and 18d and the method of moving the rectangle 18, see steps SA1 and SA2.
Since it is the same as the above, its explanation is omitted.

Next, at step SA5, as shown in FIG. 7A, the image information corresponding to the rectangle 18 whose four sides are determined is cut out by the cutting means. The image information to be cut out is extracted from the simple pattern 19 in order to reduce the load on the processing device 8 by various processes described later. To cut out the image information, for example, in the processing device 8, a portion (a part of the simple pattern 19) located in the rectangle 18 is calculated from the coordinates of the rectangle 18 and the shapes of the four sides, and the rectangle information 18 is calculated.
It is stored in the storage device 10 as E.

Next, in step SA6, the processing device 8
However, the rectangular information 18E is repeated 3 × 3 by the fitting means to form the base 20 as shown in FIG. 7B.
In this repeat process, copying is not performed on the same VRAM, and the rectangular information 18E stored in the storage device 10 is arranged on each VRAM so that it can be combined vertically and horizontally, but it is copied on the same VRAM. Is also good. At this time, the left side 18a and the right side 18b, and the upper side 18c and the lower side 18d of the rectangular information 18E have the same shape, and therefore the adjacent rectangular information 18 is included.
E, 18E, ... Are fitted and displayed on the monitor 17 in the same state as in the hair removal combination (hereinafter referred to as the hair removal state).

Next, at step SA7, the processing device 8 reads out the reference dimension data described later from the storage device 10,
A rectangular frame 21 corresponding to the data is generated. Then, when the display data corresponding to the frame 21 is supplied to the monitor 17, the frame 21 is displayed on the upper layer of the base 20 displayed on the monitor 17 (see FIG. 7B). Here, the operator operates the input device 9 so that the patterns on the left side and the right side and the patterns on the upper side and the lower side of the displayed frame 21 are continuous.
Move 1 In practice, among the pieces of rectangular information 18E that form the base 20, the frame that connects the centers of the rectangular information 18E at the four corners is the frame 21.

Then, when the movement of the frame 21 is completed and the predetermined input data is supplied from the input device 9, the processing device 8 performs the arithmetic processing for cutting out the base 20 surrounded by the frame 21 by the second cutting means. Then, the endless version 22 is created. At this stage, the image roughness density of the endless plate 22 is rough. Next, the process proceeds to step S6 (see FIG. 4).

In step S6, the processing device 8 changes the pattern (rough image data) of the endless plate 22 into a pattern (image data) having a high image rough density. The processing device 8 reads out the image information associated with the rough image data of the endless plate 22 from the storage device 10 and performs arithmetic processing for cutting out a portion corresponding to the endless plate 22 to obtain the endless plate 2
Create 2.

Next, in step S7, the endless version 2
2 is repeated to create a baby version. The processing device 8 first reads the copy development area information stored in the storage device 10 and displays a rectangle corresponding to the information on the monitor 17. On the monitor 17, a rectangle having a size substantially matching the screen size and the endless plate 22 are displayed. Here, the operator operates the input device 9 to move the endless plate 22 on the monitor 17.

Then, when the endless plate 22 is stopped at a desired position, images corresponding to various repeat patterns stored in the expansion pattern storage means of the storage device 10 are displayed on the monitor 17. When the operator operates the input device 9 and selects a desired pattern from these patterns, the copy developing means of the processing device 8 repeats the endless plate 22 in accordance with the selected pattern. According to the repeat pattern, the endless plate 22 is arranged as it is, or after being rotated and mirror-inverted, arranged vertically and horizontally.

The processing device 8 stores the baby plate information corresponding to the baby plate thus created in the storage device 10, and the baby plate information deviates from the rectangle corresponding to the copy development area information. Delete the information corresponding to, and monitor the baby version information existing in the rectangle 1
Supply to 7. In addition, print data corresponding to the baby plate information is supplied from the processing device 8 to the color printing machine 15. As a result, substantially the same printing result as when a proof printing plate is created can be obtained.

The operator refers to the monitor 17 or the print result and judges whether or not there is a pattern habit. When a pattern habit has occurred, retouching work is performed according to the type of pattern habit that has occurred. For the retouching work, for example, another repeat pattern is selected, each side 18a, 18b of the rectangle 18,
This is performed by changing 18c and 18d and recreating the endless plate 22.

Next, in step S8, the endless version 2
2 or the baby edition is repeated to produce the present edition. This plate is produced by supplying the engraving data or image data of the endless plate 22 to the gravure engraving device 11 online or via a storage medium such as a floppy disk,
According to the repeat pattern of the gravure engraving device 11, the gravure cylinder 12 is engraved while repeating the image data of the endless plate. Further, once the print data or image data of the endless plate 22 is outputted to the disassembled film by the output scanner 16, the disassembled film is attached to the drum 4 and scanned, and the scanning information is repeated to the gravure cylinder 12. It may be produced by engraving.

Here, the reference dimension data will be described. The endless plate-making is a plate-making method in which the print pattern of the first rotation of the gravure cylinder 12 and the print pattern of the next rotation are continuously printed. Therefore, the endless plate 22 needs to have a dimension that can divide the circumferential length of the gravure cylinder 12 on one side and a dimension that can divide the printing width on the other side. In addition, since the endless plate 22 is configured such that the upper side and the lower side, and the left side and the right side of the patterns are continuous, a frame that connects the centers of the rectangular information 18E at the four corners among the rectangular information 18E that forms the base 20. Becomes Therefore, each side of the rectangle 18 is half the size of each side of the endless plate 22 (when arranged in 3 × 3). As described above, if the circumferential length and the print width of the gravure cylinder 12 are determined by the size of the printing machine and the business specifications, the rectangle 1 that constitutes the endless plate 22.
The reference dimension data is determined only by determining the number and arrangement of eight.

As described above, according to the first embodiment, each side 18a, 18b, 18c, 18d of the rectangle 18 is constituted by an arbitrary combination of line segments (free straight line, free curved line). Therefore, each side 18a, 18b, 18
The c and 18d do not intersect with the articles forming the design. Therefore, the base 20 can be created by fitting the rectangular information 18E in a hair-pulled state, and the grid pattern generated when watermark composition is used can be eliminated.

Further, the joint of the rectangular information 18E is not recognized as a joint because it is not a continuous straight line. That is, the joint of the rectangular information 18E can be erased. Further, since a plurality of repeat patterns are stored in the storage device 10 and the endless plate 22 is repeated with the repeat pattern selected by the operator,
It is possible to eliminate the pattern pattern that occurs when the same pattern is repeated at the same pitch without recreating the endless plate 22. In addition, by using each pattern, it is possible to discover patterns that cannot be found by simple repeats.

Further, the display on the monitor 17 and the color printing machine 1 are performed without preparing a proofing printing plate corresponding to the baby plate.
Since the pattern habit can be confirmed from the output result of No. 5, it is not necessary to recreate an expensive proof printing plate when the pattern habit is confirmed. That is, while reducing the plate making cost,
Work efficiency can be improved.

Next, a second embodiment of the present invention will be described. Endless plate making system 23 according to the second embodiment
Since the configuration (see FIG. 1) is the same as that of the plate making system 1 described above, the description thereof will be omitted. However, storage device 1
0 is standard dimension data and repeat pattern information,
It stores normal image information, rotated image information, rotated image information, rotated image information obtained by rotating the mirror of the design original and scanning with the input scanner 3, and inverted image information.

In such a configuration, the processing performed by the processing device 8 is substantially the same as that of the plate making system 1. Therefore, different parts will be described with reference to FIGS. 4 and 8. When step S4 of FIG.
The simple pattern 19 and the rectangle 18 by the mask setting means shown in (a) are displayed. Here, when the operator supplies predetermined input data to the processing device 8 via the input device 9, the process proceeds to step SB1 in FIG.

Here, steps SB1 to SB3 are as shown in FIG.
Since the processing is the same as steps SA1 to SA3 in step 1, the description thereof will be omitted. When these processes are finished, the monitor 17 displays the formed rectangle 1 as shown in FIG.
8 is displayed. The rectangle 18 is masked, unlike the first embodiment, and has a configuration in which a window having a rectangular 18 shape (rectangular window 18F) is opened in the mask. here,
When predetermined input data is supplied from the input device 9 to the processing device 8, the process proceeds to step B4.

In step SB4, the rectangular window 18F is repeated. Each rectangular window 18F is copied onto a different VRAM, and a 3 × 3 rectangular group 24 is displayed on the monitor 17 by the fitting means, as shown in FIG. 9A.
Next, in step SB5, first, the rectangular windows 18 _1-1 , 18 _1-3 , 18 _3-1 , 18 _3- located at the four corners of the rectangular group 24 are first.
_The simple pattern 19 is fitted into ₃ by the pattern information fitting means.

Specifically, the simple pattern 19 is displayed in each rectangular window 1
It is on a VRAM different from that of 8F, and the operator operates the input device 9 so as to move only the simple pattern 19 to an appropriate position while referring to the monitor 17. The processing device 8 to which the input data according to this operation is supplied changes the coordinates of the simple pattern 19 according to the information. At this time, the rectangular window 18
_1-1 is masked, and as shown in FIG.
The simple pattern 19 is visible.

[0064] Then, as a simple picture 19 corresponding to the rectangular window 18 _1-1 is appropriate, after finishing moving the simplified picture 19, the operator through the input device 9, a predetermined input data It is supplied to the processing device 8. As a result, the processing device 8 has the same positional relationship as that of the rectangular window _181-1 and the simple pattern 19 with respect to the rectangular window 18 _1-3 , the rectangular window 18 _3-1 and the rectangular window 18 _3-3 . The simple pattern 19 is fitted in each. At this time, each simple pattern 19 is copied on another VRAM.

If the simple patterns 19 do not overlap each other, they may be copied in the same VRAM at first, and in that case, if the simple patterns 19 are moved in the rectangular window _181-1 ,
The simple patterns 19 copied on the same VRAM respectively have corresponding rectangular windows 18 _1-3 , rectangular windows 18 _3-1 and rectangular windows 18 _3-3.
Move similarly to. Therefore, it is possible to reduce the work of calculating the positional relationship and fitting the simple pattern 19 later.

Next, as in the case of the above-mentioned four corners, rectangular windows 18 _1-2 , 18 _2-1 , 1 corresponding to the four sides of the rectangular group 24 are formed.
Insert the simple pattern 19 into 8 _2-3 and 18 _3-2 (Fig. 9).
(See (b)). Then, the rectangular window 18 in the center of the rectangular group 24
_Fit the simple pattern 19 into _2-2 (see FIG. 9 (c)). To fit in the rectangular window 18 _2-2 , the surrounding rectangular windows 18 _1-2 ,
It is done in consideration of the balance with 18 _2-1 , 18 _2-3 , and 18 _3-2 . In this way, the simple pattern 19 is added to the rectangular group 24.
Is fitted to form the base 20 shown in FIG. 7 (b).

By the way, the simple pattern 19 used for the above-mentioned fitting work is arbitrarily selected from the patterns corresponding to various image information (image information, rotated image information, inverted image information) stored in the storage device 10. It This selection is made by predetermined input data supplied to the processing device 8 via the input device 9. When the above-described fitting process is completed and predetermined input data is supplied to the processing device 8, the process proceeds to step SB6. The processing after step SB6 is the same as the processing after step SA7 (see FIG. 5) of the first embodiment, and therefore its explanation is omitted.

As described above, the frame of the rectangular window 18F is repeated to form the rectangular group 24, and the simple pattern 19 is fitted into the rectangular group 24. You can decide. Therefore, no pattern habit occurs when the base 20 is created. That is, the work of forming the base 20 is completed once.

In particular, in the first embodiment, the rectangular group 20
In the case of constructing the rectangular information 18E having different patterns, it is necessary to imagine a whole combination to create a plurality of rectangular information 18E, but this is not necessary in the second embodiment. At this time, the same simple pattern 19 to be fitted may be the same, but its position may be changed.
By arbitrarily selecting from the simple pattern 19 corresponding to various image information (rotated image information, etc.) stored in the same pattern, the repetition of the same pattern is further reduced than simply changing the position, and the same pattern can be more surely made the same. It is possible to eliminate the habit that occurs when repeating on the pitch.

Further, even if a pattern habit occurs, the pattern habit can be eliminated by simply changing the fitted pattern. Further, since the rotated image information and the inverted image information obtained by rotating and mirror-reversing the pattern original are stored in the storage device 10 in advance, it is not necessary to create these information by calculation from the normal image information. The time for image processing can be shortened. Therefore, the work efficiency can be improved.

Next, a third embodiment of the present invention will be described. Endless plate making system 25 according to the third embodiment
The difference (see FIG. 1) from the plate making system 23 according to the second embodiment described above is only the processing contents and the configuration is the same, so the description thereof is omitted. Hereinafter, in the processing performed by the processing device 8 or the operator, parts different from the plate making system 23 will be described with reference to FIGS.
Will be described with reference to.

First, when step S4 in FIG. 4 is completed,
A simple pattern 19 and a rectangle 18 formed by the mask setting means shown in FIG. 6A are displayed on the monitor 17. This rectangle 1
8 is masked unlike the first embodiment, and has a configuration in which a window having a rectangular shape 18 (rectangular window 18G) is opened in the mask. Here, when the operator supplies predetermined input data to the processing device 8 via the input device 9, the process proceeds to step SC1 in FIG. In step SC1, the operator operates the input device 9 to move the left side 18 of the rectangular window 18G.
a, the upper side 18c (see FIG. 11B) is determined. As described above, the left side 18a and the upper side 18c are the simple patterns 19
It is a combination of line segments (free straight line, free curved line) that avoids the articles inside.

Next, in step SC2, the rectangular window 18G
Is repeated. Each rectangular window 18G has a different VR
After being copied on the AM, a 3 × 3 rectangular group 26 is created on the monitor 17 by the overlapping means as shown in FIG. As shown in FIG. 11C, the left side 18a and the upper side 18c are preferentially displayed in the rectangular window 18G in the overlapping portion.

Next, in step SC3, the rectangular windows 18 at the four corners of the rectangular group 26 are formed as in step SB5 of FIG.
_1-1, 18 _1-3, 18 _3-1, 18 _3-3, a rectangular window 18 _1-2 corresponding to the four sides, 18 _2-1, 18 _2-3, 18 _3-2, central rectangular window 18 _The simple pattern 19 is sequentially fitted into _2-2 (see FIG. 11 (c), FIG. 12 (a), and FIG. 12 (b)).
The base 20 thus created is shown in FIG. Then, the process proceeds to step SC4. Step S
Since the processing after C4 is the same as the processing after step SB6 (see FIG. 8) of the second embodiment, the description thereof will be omitted.

As described above, only the left side 18a and the upper side 18c of the rectangular window 18G may be constructed so as not to intersect the article, so that the sides 18a and 18c can be easily determined. In addition, in each of the above-described embodiments, the rectangular information 18E, the rectangular window 18F, or the rectangular window 18G is repeated to form the 3 × 3 base 20, the rectangular group 24, or the rectangular group 26, but the present invention is not limited to this. It is not necessary to repeat, and it may be made to repeat in an arbitrary number of combinations.
