Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a method for printing leaflets and catalogs, and particularly to a method for printing leaflets and catalogs in which an original plate is created using a computer.

(Prior Art) Flyers and catalogs generally have product photos, names, model numbers, prices, explanatory drawings, frames, etc. arranged in predetermined positions. For this reason, in these printing processes, the designs for flyers and catalogs are usually converted into line drawings,
We will deal with photos and text separately. FIG. 2 shows a process diagram of a conventional leaflet printing process. Now, consider printing a flyer as shown in FIG. First, the designer creates a design paper 2 based on the layout instruction 1 from the orderer. As a result, the overall composition as shown in FIG. 3 is roughly determined. Next, a ruled draft 3 is performed based on this design paper. As shown in FIG. 4, the ruled block is drawn by extracting items that can be treated as line drawings, such as frames, ruled lines, and character position designation lines. For the photo part of the product, a paper printing process 5 is performed in which the film manuscript 4 is enlarged or reduced to a predetermined size and printed, and this is cut and pasted along the outline of the product to create a photo plate as shown in Figure 5. Perform step 6 to create the photo version. For the text of product names, prices, etc., use a phototypesetting machine 8 to stamp out the text based on the product list 7, and then cut and paste to create a text block as shown in Figure 6. Perform character block creation 9.

Next, on top of the ruled block shown in Fig. 4, the photographic block shown in Fig. 5 and the text block shown in Fig. 6 are superimposed to complete the design shown in Fig. 3, and the block proof proof 10 I do. If there are any corrections, create the ruled block, photo block, and text block again. When the block proofing 10 is completed, color-based original plates are created 16 based on these blocks, but at this time, separate process processing is performed for the ruled block, photo block, and text block. be exposed. First, for the bottom of the ruled block, camera photography 11 for the bottom of the ruled block is performed, and a negative plate for the line drawing as shown in FIG. 7 is created. Regarding the photographic version, instead of photographing the photographic version as it is, the original film original is decomposed 12 using a scanner, and this is cut and pasted to create a film original 14. When performing scanner decomposition, yellow (Y), magenta (M),
If each film is used for cyan (C) and black (B _L ), Y, M, C, and B _L are used as shown in Figure 8.
An original film version will be created. Regarding the character block, the camera photographing 13 of the character block is performed in the same way as the ruled block, and a negative plate of the characters as shown in FIG. 9 is created. At the same time, cutout mask plate creation 15 is performed. This cutout mask plate is for covering a part of the film original plate, etc., and is, for example, as shown in FIG. 10. A set of the negative plate, film original plate, and cutout mask plate created in this way becomes a color-based original plate. In this process of color-based original plate creation 16, necessary shading processing is also performed.

Next, a printing plate/proof printing 17 is performed using this identification original plate, and based on the results, color-based original plate correction 18 is performed if necessary. After the correction is completed, printing 19 is performed.

(Problems to be Solved by the Invention) The conventional printing method as described above is disadvantageous in that it relies heavily on manual work, and when corrections are made, the work load is extremely heavy. In particular, the layout of flyers and catalogs often needs to be revised many times, and prices are often changed just before the printing process, resulting in very poor work efficiency. For example, when making corrections at the stage of proofreading 10, it is necessary to manually create the lined version, photo version, and text version again. As described above, a more efficient printing method has been desired for some time.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a method for printing leaflets and catalogs, which allows for easy mid-stage corrections and efficient printing.

[Structure of the invention]

(Means for Solving the Problems) A feature of the present invention is that in a method for printing leaflets and catalogs, the design of the leaflets and catalogs to be printed is divided into line drawings, photographs, and characters, and the divided line drawings,
The photo and text data are input separately into a computer, and this computer creates a design by combining these data, performs the necessary shading processing, and outputs the results.Based on this output result, each The data is edited, a first film original plate made of a plurality of standard colors is created based on the edited photographic data, and a first film original plate made of a plurality of standard colors is created based on the edited line drawing data, character data, and shading data. Create a second film master plate, create a layout master plate that indicates the layout position of each component of the design based on each edited data, and use the first film master plate and the second film master plate to create a printing plate.
The present invention is designed so that proof printing is carried out and printing is carried out after proofreading, making it easy to make mid-stage corrections and to perform printing with high efficiency.

(Function) According to the printing method according to the present invention, the design of the flyer or catalog to be printed is inputted into a computer by dividing it into line drawings, photographs, and characters, and the necessary corrections are made by composing them on the computer. I can do it. The necessary shading work can also be done on a computer. Based on the output data of this computer, a first original film for photographs, a second original film for characters, line drawings, and halftone dots, and a layout original showing layout positions can be automatically output. .

Therefore, mid-stage corrections can be easily made, and there is no need to create each block, allowing efficient printing.

(Example) The present invention will be described below based on an illustrated example. FIG. 1 is a flow diagram of a leaflet printing process according to the present invention. Here, the same steps as those in the process diagram shown in FIG. 2 are indicated using the same reference numerals. Now, the third
Considering the case of printing a flyer as shown in the figure, layout instructions 1 for line drawings, film manuscript 4 for photographs, and product list 7 for text.
is given by the ordering party as in the conventional process. Next, based on these data, line drawings, photographs, and text data are input separately into a computer and synthesized. This process is the process of layout design 22 using the monitor. The data regarding the line drawings (including drawings, logos, illustrations, marks, etc.) given in the allocation instruction sheet 1 can be input using an input device such as a keyboard, tablet, or mouse while looking at the computer's display device. All you have to do is specify the dimensional coordinates. Data regarding the photograph is input into a computer by subjecting the film original 4 to color scanner decomposition 20. For example, it is sufficient to perform color separation for the three colors RGB and import each as raster data. Furthermore, data regarding characters is entered into a word processor 21 for the product list 7 in advance. That is, a table containing product names, explanatory text, prices, etc. is stored in the computer's storage device via a Japanese word processor. In the process of layout design 22 using the monitor, these data are combined and displayed on the display, and the layout is corrected. For example, first display line drawing data on a color monitor as a display,
Using the photographic data captured by the color scanner decomposition 20, images of each product are displayed at predetermined positions. Since the images are displayed by a computer, each layout can be easily modified using a tablet or the like. Next, a list of products already loaded into the computer is searched, and character data such as product names and prices are displayed at predetermined positions. In addition, shading processing is performed as necessary. As a result, an image of the design as shown in FIG. 3 is obtained on the color monitor.

When the final layout design is completed, output this image as a hard copy and check the output image 2.
Do step 3. This step corresponds to the step of proofreading 10 in the conventional method shown in FIG. In the conventional method, it was necessary to create a ruled block, a photo block, and a text block before reaching this stage, but with the method of the present invention, these blocks are not necessary at all, and all of them can be created. The data will be stored in the computer's storage device. Therefore, the effort required to reach this stage is greatly reduced. Moreover,
Since the result is obtained as a color hard copy, the orderer can check it while looking at an image that is almost the same as the finished flyer. If it becomes necessary to make corrections at this checking stage, the process of layout design 22 using the monitor may be repeated again. There is no need to recreate the original as in the past, and it is only necessary to output a hard copy after inputting the required corrections while looking at the color monitor. As described above, the major features of the present invention are
The layout design process can be carried out in an interactive format while constantly watching the monitor, and furthermore, the layout design process can be checked by making a hard copy of the creation screen.

After checking the output image, the printing process proceeds based on this image. That is, first, color-based original plates are created 16, but since all data of line drawings, photographs, and characters are stored in the computer,
Create a copy for each as before,
There's no need to take a camera to capture this. For photographs, automatic scanner film original output 24 is performed, and a first film original consisting of four sheets Y, M, C, and B _L as shown in FIG. 8 is automatically created by a computer. Data about each photo has already been input into the computer's storage device in the color scanner separation 20 process, and data about the layout position of each photo has also been given to the computer, so it is easy to use the scanner film output device. When connected to a computer, film master plates can be created automatically.

On the other hand, for line drawings, characters, and plain dots, the original film is automatically output 25 using a film printer.
Y, M, C, B _L automatically by computer
A second film master plate consisting of four sheets is created.

For example, suppose that the image for which the check has been completed has a design as shown in FIG. Each component of the design shown in Figure 11 is yellow (Y) and magenta.
(M), cyan (C), and black ( _BL ), but for the sake of explanation, each component has a halftone density as shown in the diagram. Consider the case where the image is printed as a composite of reference colors.
For example, the letter a is expressed with a composite color of 100% yellow (Y) and 100% magenta (M), and the ruled line b (a type of line drawing) is
It is expressed with 100% black (B _L ), and the flat mesh C is yellow (Y) 50%.
% and cyan (C) 50%.

The second image that is automatically output based on such a design
The film originals are as shown in Figure 12 for yellow (Y), Figure 13 for magenta (M), Figure 14 for cyan (C), and Figure 15 for black ( _BL ). In both cases, for each constituent element except photographs d and g, a portion including each reference color is output.

In the process of automatically outputting a film original plate 25 by the film plotter, a layout original plate as shown in FIG. 16 is also automatically outputted. This layout original plate indicates the layout position of each component, and corresponds to what is called an "atari version."

The first original film output as described above,
By positioning and combining the second film original using the layout plate, the step of creating originals for different colors 16 is completed.

There is no longer any need to take pictures of each block with a camera or manually typesetting, as was done in the past.
After this, as in the conventional process, a printing plate/proof printing 17 is performed, and if there is a correction, a color-specific original plate correction 18 is performed, and after the correction is completed, printing 19 is performed.

〔Effect of the invention〕

As described above, according to the present invention, in the method for printing flyers and catalogs, the design of the flyers and catalogs to be printed is divided into line drawings, photographs, and characters and input into a computer, and these are combined on the computer and necessary. We made several corrections and automatically created color-specific master plates based on the computer output data, making it easy to make mid-stage corrections and eliminating the need to create each master plate, increasing efficiency. You will be able to perform good printing.
