BRIEF SUMMARY
DESCRIPTION
1. Technical Field
The present invention relates to a method printing leaflets, catalogs or the like, and more particularly to a method of printing leaflets, catalogs or the like which prepares printing plates using a computer.
2. Background Art
On predetermined positions of leaflets, catalogs or the like, there are arranged in general a photograph showing the appearance of goods, the trade name, the model number, the price, its explanatory view, a border and the like. For this reason, designs of leaflets, catalogs or the like are ordinarily handled with each being classified into line drawings, photographs and characters in the process for printing these leaflets, catalogs or the like. A diagrammatical view of a working process for leaflets which has been generally carried out in the art is shown in FIG. 1. It is now assumed that the printing of a leaflet as shown in FIG. 2 is conducted. First, a designer effects laying out line drawings 2 on the basis of a layout instruction 1 from a person who has given an order. Thus, the entire composition as shown in FIG. 2 is roughly determined. Then, drawing a block copy for line drawings 3 is carried out on the basis of the line drawings thus laid out. The border, rules, character position designating lines etc. which can be handled as line drawings as shown in FIG. 3 are extracted and they are described on the block copy for line drawings. With respect to the photographic portions of the goods, preparing photo-print 5 which expands or reduces photo-films 4 so that they have a predetermined size is carried out. The photo-printed films are patched along contour lines of the goods. Thus, preparing a block copy for photographs 6 is conducted and a block copy for photographs as shown in FIG. 4 is obtained. In addition, with respect to the characters such as the trade name or the price, a manual phototype setting 8 is conducted using a phototype setter on the basis of a merchandise list 7, thereby to print out characters. By patching these characters thus printed out, preparing a block copy for characters 9 is carried out and a block copy for characters as shown in FIG. 5 is obtained.
Then, on the block copy for line drawings shown in FIG. 3, the block copy for photographs shown in FIG. 4 and the block copy for characters shown in FIG. 5 are stacked, thus to complete the design as shown in FIG. 2 to carry out proofreading block films. If modification is required, the block copies for line drawings, photographs and characters are prepared for a second time. When the proofreading of the block copies is completed, preparing assembled films 16 will be conducted on the basis of these block copies. At this time, for block copies for line drawings, photographs and characters, different processes are carried out, respectively. First, with respect to the block copy for line drawings, photographing a block copy for line drawings 11 is conducted, and a negative plate in respect to the line drawings as shown in FIG. 6 is made up. With respect to the block copy for photographs, the block copy for photographs itself is not subjected to photographing as it is, but the original photo-films 4 are subjected to color separation 12. Then, by patching these color-separated photo-films, separation films 14 are prepared. When carrying out color separation, by using filters of yellow (Y), magenta (M), cyanogen (C) and black (B.sub.L), separation films with respect to Y, M, C and B.sub.L are prepared as shown in FIG. 7. In addition, with respect to the block copy for characters, photographing a block copy for characters 13 is carried out in the same manner as the block copy for line drawings. Thus, a negative plate relating to characters as shown in FIG. 8, is prepared, and at the same time preparing a mask is carried out. This mask serves to cover a portion of separation films etc. and is formed, for example, as shown in FIG. 9. The set of the negative plate 5, the separation films and the mask is used as assembled films.
Then, these assembled films are used to prepare press plat
