That is, the mask 281 hides areas other than the areas A1 and A2 of the printed matter 250 shown in FIG. 9, the mask 282 hides areas other than the areas B1 to B6 of the printed matter 250, and the mask 283 hides areas other than the area C1 of the printed matter 250. The mask 284 hides areas other than the areas D1 to D3 of the printed matter 250, and the mask 28
Reference numeral 5 hides areas other than the areas E1 and E2 of the printed matter 250.

Next, a transparent film having halftone dots uniformly provided at a predetermined halftone percentage (hereinafter referred to as "flat halftone") and the above masks 281-2.
A film master for each color is prepared by using 85 and this is done by overlaying a mask and a flat screen onto the film master and printing it to form halftone dots only on desired portions of the film master.

FIG. 14 shows an outline of the steps from the block copy original 260 to the production of the printed matter 250, which is 291, 292, 293, 294,
295 and 296 are flat nets, and the net percentages are 100%, 20% and 1 respectively.
It is 0%, 50%, 30%, 8%. Incidentally, these various flat screens are prepared in advance. As shown, block copy manuscript 26
As described above, the positive 271 and the negative 272 are created from 0, and the masks 281-285 are created from the positive 271.

Here, the method for producing the yellow plate 241 will be described. For this production, the masks 281, 282, 283, 284 and the flat net 29 are used.
1,292,293 are used. First, mask 281 and flat net 291
And 10 are overlapped with each other and baked on the film original plate to form 10% halftone dots in the area A. Then, the mask 282 and the flat screen 292 are printed on top of each other, the mask 283 and the flat screen 292 are further printed on top of each other, and finally the mask 284 and the flat screen 291 are stacked on top of each other and printed on the same region B, C of the same film original plate, A yellow plate 241 is prepared by forming halftone dots of 20%, 20%, and 100% on D, respectively. Similarly, from the masks 281, 282, 283 and the flat nets 294, 295, 293, the magenta plate 242, the masks 281, 282, 283, 285 and the flat net 292,
Cyan version 243 is created from 293 and 296.

Further, since the black plate 244 is composed only of the contour lines drawn on the block copy document 260 shown in FIG. 10, a mask is not used and it is created from the negative 272 and the flat screen 291 shown in FIG. 12 (b). It That is, the negative 272 and the flat net 291 are overlapped and baked on the film original plate to form 100% halftone dots on the contour line portion, and the black plate 244 is produced.

Yellow version 241, magenta version 2 created in this way
A printing plate is created from 42, cyan plate 243, and black plate 244, and overprinted using ink and paper, and printed matter 50
Is created.

As described above, the conventional plate making process of the solid mesh part is a complicated process using various masks and flat screens and is performed by hand, so that it takes a long time to make the final film original plate of each color. In addition to the above, there is a problem that an error in the position of the pattern is likely to occur in the work of forming the mask and the overprinting, and it is difficult to obtain a desired printed matter. This problem was more remarkable as the design became more complicated. An apparatus for performing all the plate-making process of the solid mesh portion manually performed by using a computer was proposed by the present applicant as the invention of Japanese Patent Application No. 60-213259 or Japanese Patent Application No. 60-270501. The efficiency of the process is improved.

Here, in the apparatus for performing the plate making process of the solid mesh portion using the computer, the line image drawn on the block original is read by a scanner or the like, the read image is displayed on the display, and the image is displayed on the display. Coloring is performed to create a color image, and this color image is output to create a film original plate of each color.

FIGS. 15 (a) and 15 (b) are schematic diagrams for explaining the coloring process on the display in the above apparatus, and the coloring process of the above apparatus will be described below with reference to the drawings. First, the image data is displayed on the display 200. 15th
The image displayed as shown in FIG. 7A is a graphic 210 represented by a contour line 210K. Here, the dashed line for the figure 210
Areas 210A, 210B, 210C, 210D, 210E divided by 210L
When coloring is performed with different colors, it is performed as follows.

First, create a dashed line 210L that is a color boundary on the display 200, specify the color and area to be colored, and specify the area 210A,
210B, 210C, 210D, 210E are sequentially colored. And
The broken line 210L is sequentially replaced with the colored color. In this case, when performing the coloring process, it is necessary to specify the color of the boundary of the area to be colored and to give a protection instruction that the specified color is not colored. For example, as shown in FIG. 4 (b), if the areas 210A, 210B, 210C and 210D are colored in the area 210E when the coloring process is completed, the areas 210A, 210B
After the protection instruction is given to the colors of 210B, 210C, and 210D, the color of the area 210E is designated and the coloring process is performed.

(Problems of the prior art) However, if the protection processing is always performed on the color of the boundary portion before performing the coloring processing of each area, the operation is complicated and if the protection instruction is erroneous, it is redone and the coloring processing takes time. There was a problem that it took. This problem was remarkable especially when there were many areas to be colored.

a1, a2, b1, b2, b3, b4, b5, b6, c1, d1, d2, d3, d
Since the boundary lines have been created for all of 4, d5, e1, and e2, the next boundary line creating process (S14) is not performed, and the process proceeds to step S15 and waits for color designation. And
When the color designation is made, it waits until the coloring area is designated (S16), and when the coloring area is designated, the next coloring process is performed (S17). Here, the color designation in step S16 is
This is performed by operating the tablet 7a and the stylus pen 7b to select a color to be colored from the color scale 61a.
By operating the stylus pen 7b, the respective regions a1, a2, b1, b2, b of the image displayed on the display 6 to be colored.
It is performed by designating an arbitrary point within 3, b4, b5, b6, c1, d1, d2, d3, d4, d5, e1, e2. Further, in the coloring process of step S17, the pixel scanning means 5a sequentially scans the pixels around the pixel in the area designated in step S16 as a starting point, and with respect to the scanned pixels, The pixel color replacement means 5b replaces only the pixel of the same color as the pixel of the point designated in step S16 with the color selected from the color scale 61a in step S15.

Then, it is determined whether or not the coloring process is completed (S1
8) If not completed, the process returns to step S13, and the process from step S13 onward is performed on the next area.

In this manner, the respective areas a1, a2, b1, b2, b3, b4, b5, b6 of the image displayed on the display 6 in step S12,
c1, d1, d2, d3, d4, d5, e1 and e2 are colored with a designated color, and when this coloring process is completed, the colored image data registration means 5c magnetically colors the colored image data on the display 6. It is registered in the disk device 4 (S19).

If the auxiliary document 20 shown in FIG. 1 is not used, YES is selected in step S13 and boundary lines of colors corresponding to various auxiliary lines on the auxiliary document 20 are created (S14).

Further, the image data of the block copy document stored in the magnetic disk device 4 is only a circular contour line as shown in FIG. 15 (a), and the inside thereof is shown on the display panel 6 in FIG. 15 (b). When coloring with a plurality of colors, the procedure is as follows.

First, similarly to the above, the image data stored in the magnetic disk device 4 is read (S11) and displayed on the display 6 (S12). In this case, on the display 6, as shown in FIG. 6A, only the outline 60k indicated by the solid line is displayed in the image display area 60, and the color to be colored is read from the color memory 8 on the color scale 61a. Has been displayed.

In the determination of whether to create the boundary line in step S13, YES is selected and the next boundary line is created (S14).
In creating the boundary line, the tablet 7a and the stylus pen 7b are operated to select the boundary line creation menu 61b, and the color of the boundary line is selected from the color scale 61a. ) Create a boundary line indicated by broken line 60L. As shown in the figure, the inside of the contour line 60K is divided into regions 60A to 60E by the creation of this boundary line.

Then, for each of the regions 60A to 60E, the color designation and the designation of the colored region are performed in the same manner as described above, and the coloring process is performed. At this time, in the coloring process of step S17, the pixel scanning means 5a sequentially scans the surrounding pixels from the pixel of the point in the area designated in step S16 as a starting point,
For this scanned pixel, the pixel color replacement means 5b replaces only the pixel of the same color as the pixel of the point designated in step S16 with the color selected from the color scale 61a in step S15, so that the area already exists. Even if the coloring process is completed for 30A to 30D and the coloring process is performed on the region 30E, the color to be colored and The coloring process of the region 30E is immediately performed only by designating the region.

In this way, the areas 60A to 60E of the image displayed on the display 6 in step S12 are colored in the designated color as shown in FIG. 6 (b). Then, when this coloring process is completed, the colored image data registration means 5c is executed as described above.

FIG. 3 is an explanatory view of a color table used for the above, and the operation of making a film original plate for each color will be described below based on the drawing.

First, the keyboard 9 is operated to give a start signal, the colored image data stored in the magnetic disk device 4 is read (S31), and the double processing is performed (S32). The dubbing process is a process for sloping the boundary between colors, and in the case of the printed matter 250 shown in FIG. 9, the above areas a1, a2, b1, b2, b3, b
4, b5, b6, d1, d2, d3, d4, d5, e1, e2 may be slightly covered with the contour line.

Then, enlarged image creation is performed (S33). In the enlarged image creation, the image is enlarged to the output resolution by interpolation with respect to the colored image data, and smoothing processing for removing the roughness of the contour line of the enlarged image is performed. Then, the scanner 1 is created by this enlarged image creation.
The pixel density of the image data taken in is converted into the pixel density for the film original plate, but in this embodiment, the image data of 18 lines / mm is converted into the image data of 72 lines / mm. The pixel density after conversion is not limited to the above example, but 30
It should be about / mm or more.

After this, data conversion processing is performed (S34). The data conversion process is performed by enlarging the regions a1, a2, b1, b2, b3, b4, b5, b6, c1, d1, d2, d of the enlarged image created in step S33.
Colored image data of 3, d4, d5, and e1 are shown in FIG.
The color table shown in (b) is used to convert halftone data of yellow, magenta, cyan, and black specified in the color specification sheet. In this color table, as shown in the drawing, a color number is given to each combination of halftone percentages of yellow (Y), magenta (M), cyan (C), and black (K), and FIG. Color table 28
Is the color table 29 of the image shown in FIG.
Shows a color table of the image shown in FIG. The color numbers of the color tables 28 and 29 are associated with the color data stored in the color memory 8 and registered in the host computer 5. Therefore, the step
The colored image data colored with the color of the color scale 61a shown in FIGS. 5 and 6 by the data conversion processing in S34 is displayed in the color tables 28 and 29 as yellow, magenta, cyan, and black halftone data, that is, color. Converted to decomposed data.

Next, the color separation data created by the data conversion in step S34 is sent to the data bus 3 shown in FIG. 1 and output to the film original plate set on the scanner 10 through the interface 11 to obtain a desired color for each color. A film original plate on which halftone dots are formed is created (S35).
