DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to printing of a building material having an abstract pattern, and more particularly to a simulation system for designing 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. 14 shows an outline of a conventional plate making process for an abstract pattern. As shown in FIG. 14A, first, when a unit material of an abstract pattern composed of a design image, a photograph, and the like is submitted, the unit material is photographed with a plate-making camera to create a separation film, and the separation film is eliminated. In order to do this, the stencils are repeated one after another by film synthesis while applying an appropriate mask, and a baby slab, that is, a small stencil for proof printing is created. The film of the unit material is usually about 3 to 5 cm square, but as shown in FIG. 14B, the film 101 is repeated nine times or more in each direction to create a plate about 1 m square. can do. This is the baby version 102. However, usually, an endless plate in which the film 101 is repeated about three times vertically and horizontally is created as an intermediate stage without directly creating a baby plate. 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. Make a plate and proof again. In this way, when a desired abstract pattern is obtained, printing is performed by this machine.

[0004] The printing of building materials is performed by the above steps. Unlike general commercial printing or publishing printing, the number of printing plates used for printing building materials differs depending on the item. Are different from each other, and the colors used for printing are cyan (C), magenta (M), yellow (Y),
Instead of the four colors of black (K), a special color designated for each plate is used. For example, as shown in FIG.
And the diagonal pattern of the left edge having a color of _1, assuming that printing abstract patterns having a diagonal pattern of downward-sloping with color that CL _2, in the case of commercial printing and publication printing color separation pattern of FIG. 15A Then, C, M, Y, and K color plates having the same pattern are prepared. The C color plate is a cyan ink, the M color plate is a magenta ink, the Y color plate is a yellow ink, and the K color plate is a yellow ink. Each color plate is printed with black ink, but in building material printing, for example,
Create two separations separations having a diagonal pattern of downward-sloping as shown in separations and FIG C having a diagonal pattern of lower left as shown in FIG. 15B, featured CL _1, respectively, are specified, By printing with CL ₂
Printing of a pattern having a pattern and a color as shown in FIG. 5A is performed.

[0005]

By the way, in the design of the unit material of the abstract pattern, there are several modes such as a case where a designer newly creates, and a case where a tint block pattern which has been created so far is overlapped with a pattern created by the designer. However, in any case, the creation of a completely new pattern is required, so that a very high level of design ability is required, and as a result, there has been a problem that the workload is extremely large. On the other hand, in recent years, attempts have been made to design an abstract pattern using a paint system using computer graphics or the like, but the operation performed there is performed by using a mouse or a stylus pen to display a desired pattern on the display screen. This is an operation of drawing, which is not different from the operation of drawing a desired pattern on a paper using a paintbrush, and does not reduce the work load. In addition, a pattern created by a designer and a copy-forgery-inhibited pattern that have been created so far have been conventionally superimposed by superimposing a pattern film and a copy-forgery-inhibited pattern film on a plate making film and synthesizing them photographically.
However, selecting a copy-forgery-inhibited pattern film to be combined with a copy-forgery-inhibited pattern film requires skill, and it is performed by trial and error, which takes a great deal of time. In addition, when combining a pattern pattern and a copy-forgery-inhibited pattern pattern, Since it is necessary to adjust the pitch, one of the patterns is enlarged or reduced using a plate making camera, or one of the patterns is rotated as necessary, and further, gradation adjustment work such as contrast adjustment and brightness adjustment , The work load was very large. The present invention solves the above-mentioned problems, and particularly, a building that can easily design a new abstract pattern used as a unit material.
An object of the present invention is to provide an abstract pattern design simulation system for printing materials .

[0006]

It is considered that an abstract pattern can be designed by variously combining basic tint block patterns. The present invention is based on such a concept. A tint block pattern is stored in a database, and two desired tint block patterns are searched from the database, and the two tint block patterns are synthesized by a desired operation. Create a separation pattern and add a special color, select the desired separation pattern from the created separation patterns and combine them to create an abstract pattern pattern to be used as a unit material and create a color image The present invention intends to simulate an abstract pattern design by outputting the image data. For this purpose, the present invention provides an input device, a color image display device, a color image recording device for performing a color hard copy, and a sand material used for building material printing. A tint block pattern database storage unit for storing tint block patterns of abstract patterns such as eyes, cloth, and stones; When a copy-forgery-inhibited pattern to be searched is specified by an input device and an image memory having a copy-forgery-inhibited pattern area, the specified copy-forgery-inhibited pattern is searched from the copy-forgery-inhibited pattern stored in the copy-forgery-inhibited pattern database storage unit. A copy-forgery-inhibited pattern database search unit that displays the obtained copy-forgery-inhibited pattern in a predetermined number on the color display device, and writes the copy-forgery-inhibited pattern selected by the input device from the search result into the pattern memory area of the image memory; An operator for addition, subtraction, AND, OR, and exclusive OR synthesis is provided. A copy-forgery-inhibited pattern written in two pattern memory areas in the image memory is selected, and an operation for synthesis is performed. When a child is specified, the two selected tint block patterns are combined by the specified operator. An image synthesizing unit that registers the synthesized pattern as a color separation pattern; a color processing unit that applies a special color instructed by an input device to the color separation pattern registered by the image synthesis unit; The separation pattern to which the special color is given by the part is designated as R, G, B
To the color display device in the plate system or C, M, Y, K
And an output processing unit for outputting to the color image recording apparatus in the four-plate system. Therefore, according to the abstract pattern design simulation system for building material printing according to the present invention, the operator can easily and quickly simulate the abstract pattern design simply by performing simple operations such as menu selection and setting of special colors. Therefore, the efficiency of abstract pattern design and plate making can be greatly improved.

Denotes a coloring processing unit, and 15 denotes an output processing unit.

First, the configuration and function of each unit shown in FIG. 1 will be described. The input scanner 1 is composed of a drum scanner used in a layout scanner or the like. However, in the present invention, there is no need to perform color separation, so a monochrome scanner is used. The control device 2 is mainly configured by a microprocessor, and manages operations of each device and each unit of the abstract pattern design system according to the present invention. The input device 3 is for instructing a menu of a desired process and the like, and includes a keyboard and a pointing device such as a mouse. The color CRT 4 is arranged as a display device, and includes a driving circuit such as a synchronizing signal generation circuit and a frame memory as a video RAM for displaying a predetermined image. It is to be noted that any display device may be used as long as it can perform color display, and it is natural that a color liquid crystal display device or the like can be used instead of the color CRT. The color hard copy 5 is a full-color image recording device that outputs a color image as a hard copy, and is configured by a color inkjet printer, a color sublimation transfer printer, or the like. The original pattern memory unit 6 is for storing image data of a pattern created by a designer. The DB storage unit 7 stores a tint block pattern used for an abstract pattern design, and is composed of, for example, a high-speed magnetic disk device. D
The B registration unit 8 performs a process for newly registering the copy-forgery-inhibited pattern in the DB storage unit 7. The DB search unit 9
The processing for searching for the specified copy-forgery-inhibited pattern from the copy-forgery-inhibited pattern stored in the DB storage unit 7 is performed. The image memory unit 10 is a buffer memory for temporarily storing the copy-forgery-inhibited pattern read from the DB storage unit 7, the combined pattern obtained as a result of the image combining operation, and the like. As shown in FIG. The background pattern read from the storage unit 8, the pattern pattern obtained as a result of the enlargement, reduction, rotation, and gradation correction performed by the image synthesis processing unit 11, the pattern memory area in which the composite pattern is written, and the color separation pattern Area, a color pattern memory area for performing a coloring process when outputting to the color CRT 4 or the color hard copy 5, and a composite version memory in which a pattern to be output to the color CRT 4 or the color hard copy 5 is written An area is reserved. Details of these will be described later. In FIG. 2, four types of separation patterns can be written.
Five or more types may be written, or three or less types may be written. The affine transformation unit 11, as shown in FIG.
The pattern written in the pattern memory 1 or 2 is subjected to image processing for enlarging or reducing at a specified magnification or rotating at a specified angle, and the result is written to the pattern memory 1 or 2. is there. It goes without saying that the image processing is performed on which pattern memory is written to which pattern memory, and which pattern memory is to be written, from the input device 3 by the operator. The pixel interpolation at the time of enlargement is performed by so-called bilinear interpolation in which interpolation is performed using an average value of adjacent pixel values. Note that the details of the affine transformation circuit are well-known and will not be described. Gradation correction unit 12
Performs various tone corrections such as sharpness correction, blur correction, contrast correction, brightness correction, and black-and-white inversion on a copy-forgery-inhibited pattern or an original pattern. For example, as shown in FIG. In this case, the designated gradation correction is performed on the pattern written in the pattern memory 2, and the result is written in the pattern memory 1 or 2. It is natural that the operator instructs from the input device 3 which of the pattern memories is to be subjected to which gradation correction and to which pattern memory the result is to be written. Since various circuit configurations for gradation correction are known, details thereof will be omitted.

As shown in FIG. 5, the image synthesizing section 13 reads out the patterns written in the pattern memories 1 and 2, performs the specified operation on these two patterns, and stores the result in the pattern memories 1 and 2. This is written in 2 or 3, and is composed of a scroll unit 16 and a logical operation unit 17. The scroll unit 16 is used to move one of the two patterns to be combined up, down, left and right, and is activated when the patterns of the two patterns to be combined are matched or shifted by a desired amount. The logical operation unit 17 performs a composite operation of two patterns, and includes addition (+), subtraction (-), dissolve (watermark synthesis), and A
Operators such as ND, OR, EXOR (exclusive OR) are provided. Now, the density values of the pixels corresponding to the two copy-forgery-inhibited pattern patterns to be synthesized are D ₁ and D ₂ , respectively.
Then, the addition “+” means (D ₁ +
D ₂ ) is an operator that performs the operation of (D ₂ ), subtraction “−” is an operator that performs the operation of (D ₁ -D ₂ ) or (D ₂ -D ₁ ) for all pixels, and the dissolve is Is an operator that performs the operation of (aD ₁ + bD ₂ ) (where a + b = 1). When the image data is 8 bits / pixel, the density value is 0 to 255.
When the value is 6 or more, the density value is set to 255. Similarly, when the subtraction results in a negative number, the density value is set to 0. Further, the constants a and b at the time of dissolving may be fixedly set in the image synthesizing unit 13 in advance, or may be arbitrarily set by the operator. AND, OR, EX
The OR operator performs a logical operation for each bit of the density value of the corresponding pixel of the two copy-forgery-inhibited patterns, and if the density values of the respective pixels are now "01100110" and "11001100", the combined The density value of the pixel at the corresponding address in the pattern is “01000100” in the AND operation, “11101110” in the OR operation, and “10101” in the EXOR operation.
101010 ". The coloring processing unit 14 performs a process of giving the specified spot color to the created separation pattern. The details will be described later. Output processing unit 1
Reference numeral 5 denotes a color conversion of the designed unit material by converting the color separation pattern data provided with a predetermined special color into a three-plate system of R, G, B or a four-plate system of C, M, Y, K. The processing for outputting to the CRT 5 or the color hard copy 7 is performed.

Next, an abstract pattern design for building material printing shown in FIG.
The operation of each unit will be described along the steps in a case where a simulation of an abstract pattern design is performed using the in-simulation system . (1) DB registration of copy-forgery-inhibited pattern Pattern This is a process for registering a copy-forgery-inhibited pattern used as a material when performing a new abstract pattern design in the DB storage unit 7.
First, the operator sets a composition having a desired copy-forgery-inhibited pattern or a composition corresponding to the composition in the input scanner 1 and selects a DB registration menu with the input device 3. Thereby, the control device 2 activates the input scanner 1 and the DB registration unit 8. The input scanner 1 starts reading, decomposes the copy-forgery-inhibited pattern at a predetermined pixel density, and outputs digital image data of a predetermined number of bits, for example, 8 bits / pixel. The DB registration unit 8 stores the image data output from the input scanner 1 in a predetermined size, for example, 512 pixels × 51.
Trim to an image size of 2 pixels, assign a registration number,
Processing such as generation of a write address to the DB storage unit 7 is performed. Thus, the read image data of the copy-forgery-inhibited pattern is stored in the D
The copy-forgery-inhibited pattern is stored in the B storage unit 7, and the copy-forgery-inhibited pattern DB is constructed in this manner. It is to be noted that what kind of copy-forgery-inhibited pattern is registered as a DB is arbitrary. However, since the copy-forgery-inhibited pattern DB is the basis of an abstract design, it is necessary to systematically register basic copy-forgery-inhibited pattern having different properties. Is good.

(2) Writing Original Pattern Data The original pattern newly created by the designer and the tint block DB
In the case of designing an abstract pattern by synthesizing with the tint block pattern stored in the original pattern memory, the original pattern is written in the original pattern memory unit 6. This may be performed by reading the original pattern with the input scanner 1 or storing image data read by a conventional layout scanner.

(3) Search for tint block DB This is a step of selecting a tint block pattern to be used for the abstract pattern design from the tint block patterns stored in the DB storage section 7. When the classification item of the tint block pattern is designated by the input device 3, the control device 2
The search unit 9 is activated, and the display of a screen for DB search is instructed to the color CRT 4. Thereby, the color C
An image as shown in FIG. 6 is displayed on the screen of RT4.
In FIG. 6, two windows W ₁ and W ₂ are displayed on the screen 18 of the color CRT 4, various operation menus are displayed on the window W ₁ , and the DB storage unit 7 is displayed on the window W _{2 although} not shown. The number of copy-forgery-inhibited pattern belonging to the designated classification item from the copy-forgery-inhibited pattern stored in the pattern pattern is reduced by a predetermined number and displayed. Although sixteen background pattern in FIG. 6 have been made to appear, the operation menu window W _1, 16 division display of a background pattern, 64 split display, quad view, background pattern, such as a full-size display Is provided so that the image of the tint block pattern can be enlarged or reduced as appropriate. The operation of the scroll up / down as shown in FIG. 6 is a menu for sequentially shifting the display of a background pattern, for example, are sequentially one by one off and instructs scrolling up the upper left of the tint block pattern of the window W ₂ from the screen Then, the image of the next copy-forgery-inhibited pattern is newly displayed at the lower right. Obviously, it is also possible to scroll by one page. Note that the window W ₁ outside the above operation menu, selection key for selecting a desired background pattern, end key or the like to end the search of the tint block pattern is provided.

In the screen state shown in FIG. 6, the cursor 19 is appropriately moved by a mouse or the like to designate a desired copy-forgery-inhibited pattern, and the DB search unit 9 recognizes the designated copy-forgery-inhibited pattern and obtains an image of the copy-forgery-inhibited pattern. DB data
The data is read from the storage unit 7 and written to a predetermined position in the pattern memory area of the image memory 10, for example, the pattern memory 1 in FIG. By performing the above operation twice, the image data of the copy-forgery-inhibited pattern selected by the operator is written into the pattern memories 1 and 2 of FIG. As a result, two copy-forgery-inhibited pattern patterns can be combined as described later. However, when combining an original pattern and a copy-forgery-inhibited pattern pattern stored in the copy-forgery-inhibited pattern DB,
One of the pattern memories 1 and 2 is instructed to write the original pattern, and the other is instructed to write the searched background pattern. Although only three pattern memories are shown in FIG. 2, it is obvious that the pattern memories may have a larger capacity.

(4) Synthesis of Patterns As described above, selection of a pattern to be synthesized, that is, two background patterns or an original pattern and a background pattern,
After the completion of image processing such as gradation correction, pitch change, rotation, etc., a step of synthesizing the selected copy-forgery-inhibited pattern is performed. When an instruction to synthesize a pattern is given by the input device 3,
The control device 2 instructs the color CRT 4 to display a screen for pattern synthesis. As a result, an image as shown in FIG. 7 is displayed on the screen of the color CRT 4. In FIG. 7, four windows W are displayed on the screen 18 of the color CRT 4.
₁ , W ₂ , W ₃ , and W ₄ are displayed. Although not shown, the selected tint block pattern or original pattern is read out from the pattern memories 1 and 2 in FIG. 2 and displayed in windows W ₁ and W ₂ . is, operators for image synthesis window W _3, tone correction, is displayed operation menu affine transformation or the like. The window W ₄ is an area reserved for displaying a combined pattern obtained as a result of combining the two copy-forgery-inhibited pattern patterns displayed in the windows W ₁ and W ₂ , and a menu for combining patterns is designated. Nothing is displayed at the stage.

By the way, when synthesizing two patterns, it is necessary to adjust the pitch of the patterns of both patterns, the direction of arrangement of the patterns, or the gradation of both images as necessary. The contrast or the like may be adjusted. Tone correction displayed in the window W ₃ in FIG. 7, the affine transformation is an operation menu for it, and the contents and correction pattern to be subjected to gradation correction, gradation correction in the state of the screen shown in FIG. 7 When the write destination of the obtained pattern is designated, the gradation correction unit 12 is activated, and the designated pattern is stored in the pattern memory 1 or 2.
And performs the gradation correction designated by the above operation, and writes the result to the designated pattern memory. Similarly, when the pattern to be subjected to the affine transformation, the content of the affine transformation, and the writing destination of the pattern obtained after the affine transformation are designated in the screen state shown in FIG. 7, the affine transformation unit 11 is activated and the designated pattern is designated. Is read from the pattern memory 1 or 2, the affine transformation specified by the above operation is performed, and the result is written in the specified pattern memory. The pattern subjected to the image processing by the gradation correction and the affine transformation is read out from the pattern memory area of the image memory unit 10 and displayed on the windows W ₁ and W ₂ in FIG.

After performing image processing as necessary as described above, when an operator for synthesis is designated in the state of the screen shown in FIG. 7, the image data in the pattern memories 1 and 2 is stored in the image synthesis unit 13. The result is written in, for example, the pattern memory 3 and transferred to the color CRT ₄ to be displayed in the window W4 in FIG. Incidentally, by setting the shift amount is displayed in the window W ₃ appropriately on the screen of FIG. 7, can move one of the patterns in the synthesis of the pattern in the vertical and horizontal by a predetermined amount,
At this time, the image data read from the designated pattern memory is moved by the amount set by the scroll unit 16, transferred to the logical operation unit 17, and synthesized.

The pattern synthesized as described above is
If this is acceptable, the pattern is registered as a separation pattern in the separation pattern memory area.
Alternatively, the composite pattern can be combined with another copy-forgery-inhibited pattern by using the composite pattern as a single material by repeating the above-described operation after transplanting to the second pattern. For example, when the copy-forgery-inhibited pattern shown in FIG. 8A and the copy-forgery-inhibited pattern shown in FIG. B are selected and displayed in the windows W ₁ and W ₂ in FIG. pattern is obtained, the pattern is displayed in the window W _4. Thus, one separation pattern is created, and a desired number of separation patterns can be created by repeating the above operation.

(5) Creation and Output of Unit Material When the creation of color separation is completed, a step of creating a unit material by superimposing desired color separation and outputting the same is performed. In order to create a unit material, a special color must be instructed for each separation. However, when an instruction to create a unit material is given by the input device 3, the control device 2 activates the coloring processing unit 14. . At this time, when a color separation pattern to be colored is instructed, a display as shown in FIG. 9 is performed on the screen of the color CRT 4. 9, the window W ₁ is a region where separation pattern instructed is displayed, the window W ₂ is a region which is provided for performing an operation for instructing the color to be colored. Therefore, the operator can set a desired coloring while observing the specified separation pattern.
The setting of the color to be colored is performed by setting the percentages of the three colors C, M, and Y. The setting of the percentage may be performed by inputting a numerical value using a keyboard, or a so-called scroll bar as shown in FIG. The setting may be made with. As shown in FIG. 10, the coloring processing unit 14 includes lookup tables (LUTs) 20 to 23, an adder for C color 24, an adder for M color 25, and an adder for Y color 26. The same number of LUTs as the color separation pattern memories are prepared, and input / output density characteristics are written in each LUT based on the set coloring data. Then, C density density value, M color density value, and Y color density value of the color separation pattern are generated from the density values input from the corresponding color separation pattern memory in accordance with the set coloring data. Is the adder for C color 24 and the density value of M color is the adder 25 for M color.
Then, the Y color density value is output to the Y color adder 26. For example, in the state shown in FIG. 9, the separation pattern written in the separation pattern memory 1 has C = 100.
%, M = 80%, and Y = 30%, the coloring processing unit 14 takes in the coloring data,
An input / output density characteristic as shown in FIG. 11 is written. Therefore, assuming that the density value of the pixel input from the separation pattern memory 1 is D, D is output as the C color density value, 0.8D is output as the M color density value, and Outputs 0.3D. The outputs of the LUTs corresponding to the separation patterns that are not used are all set to 0.

Next, the color display of the unit material will be described. There are two modes of display: a display on the color CRT 4 and a mode in which a hard copy is output using the color hard copy 5. First, it is set on the color CRT 4 which separation pattern is to be combined to create a unit material. FIG. 12 shows an example of the display screen at that time. Region U ₁ for the left side of the screen 18 to display four separation _{patterns, U 2, U 3, U} 4
Is set, an area in which a pattern of a unit material created by combining desired separation patterns is displayed is set in the center, and the color set for each separation pattern is displayed on the right side. That is, in FIG. 12, the set color is displayed in the “印” mark. Although the position of the U ₄ do not see the mark "○", which indicates that the corresponding separation pattern has not been created, not set the color for coloring also be created. When a separation pattern for creating a unit material is designated on this screen, the image data of the designated separation pattern is read out from the separation pattern memory area of the image memory unit 10 in synchronization with the coloring. The C color density value, M color density value, and Y color density value that are input to the LUT of the processing unit 14 and generated by the LUT are added to the adders 24-2.
6, and the result is written into the coloring pattern memories 1, 2, 3 (FIG. 2) of the image memory unit 10.
In addition, at the time of addition in the adders 24-26, the total is 25.
If it exceeds 5, 255 is made. By the above operation, the C-plate data, the M-plate data of the unit material pattern,
Y-version data is created. The C-plane data, the M-plane data, and the Y-plane data of the pattern of the unit material are created for the following reason. That is, as described above, but it is to print with the set featured inks each separation with different patterns in building materials printing, this building material mark
An abstract pattern design simulation system for printing simulates the design of a unit material using a color CRT or color hard copy, and cannot be displayed using a special color in a color CRT or color hard copy. So, respectively, the data of R, G, B,
This is because C, M, Y, and K data must be created. Next, the image data written in the coloring pattern memories 1, 2, 3 is read out synchronously, and output processing unit 15
Is input to The output processing unit 15 includes a signal inversion circuit 28 and a hard copy processing circuit 29, as shown in FIG. The signal inverting circuit 28 inverts the C color image data, the M color image data, and the Y color image data input from the coloring pattern memories 1, 2, 3, respectively, and outputs the R signal, G signal
The hard copy processing circuit 29 generates K color data from the C, M, Y three-color image data input from the coloring pattern memories 1, 2, and 3. In addition, the C, M, and Y levels are adjusted in order to maintain the balance of the four colors, and then output.

The R, G, and B image data generated by the signal inverting circuit 28 by the above operation is written into the combined memory areas (R), (G), and (B) of the image memory section 10 and the color image data is output. It is supplied to the CRT 4 and displayed at the center of the screen 18 as shown in FIG. As a result, the final image of the unit material is displayed in the same color as the color intended by the operator, so that the quality can be easily determined. When it is desired to output not only a display on the color CRT 4 but also a hard copy, a hard copy instruction is given on the screen shown in FIG. 12, for example. According to the instruction, the hard copy processing circuit 29 stores the colored pattern memories 1 and 1
The C, M, Y three-color image data is input from 2, 3, and the C, M, Y, K four-color image data generated by the above operation is transferred to the color hard copy 5, and the hard copy is output. Is done.

(6) Output of Separation Pattern Film When printing building materials, it is customary to output the separation pattern to a film and print the plate in order to create a baby plate. In the configuration shown, for example, a method of storing image data written in a separation pattern memory area of the image memory unit 10 on a magnetic tape and outputting it to a film using a conventional layout scanner, or an appropriate communication method A method of transferring image data written in the color separation pattern memory area to the layout scanner using a line and outputting the image data as a film can be adopted. Of course, it is also possible to add an output scanner to the configuration shown in FIG. 1 to output a film, or to directly print on a gravure engraving machine using a direct printing method that has recently appeared. As described above, from the separation pattern data to which a predetermined special color is added, the three-plate system of R, G, B, or C, M, Y, K
Because of the conversion to the four-plate system, it is possible to easily output and simulate the conventional color CRT and color hard copy.

Although one embodiment of the present invention has been described above, the present invention is not limited to the above-described embodiment, and it is apparent to those skilled in the art that various modifications are possible. For example, in the above embodiment, the setting of the coloring is performed by setting the percentages of the three colors C, M, and Y.
This may be performed by setting the percentages of R, G, and B, and may be converted to C, M, Y, and K when outputting to a color hard copy. Also, the configuration of the image memory is not limited to the above embodiment, and various systems can be adopted.

[0023]

As is apparent from the above description, according to the present invention, the operator only has to perform operations such as searching for the copy-forgery-inhibited pattern, instructing the operator for synthesis, and setting the spot color. The work load can be greatly reduced as compared with. In addition, since the setting of the spot color can be easily and easily performed, different colors are provided from the same plate.
It is very effective in selecting an ink when making a so-called color change product. Furthermore, since the design of the unit material can be easily performed, not only can the design be performed in front of the customer, but also the hard copy can be provided on the spot, which is a very significant effect on sales promotion. There is. Further, if the separation pattern is stored as digital image data, the plate making efficiency can be improved as compared with the conventional manual design, and the delivery time can be shortened.
