Abstract

PURPOSE:To uniformize a heating temperature at each part and contrive enhancement of image quality, by a construction wherein a thin layer provided on one side of a biaxially stretched film is made to have a uniform thickness, and substantially the same sized openings are provided in a substantially uniform density. CONSTITUTION:A regular grating form pattern of a resin liquid is provided by screen printing on the surface of a polyester film 1 biaxially stretched to a draw ratio of about 1.5 and having a thickness of about 4mum, followed by drying for 10-15min in a chamber at 60 deg.C and leaving to stand for about 1 week, whereby a printing plate material with a pattern line width of about 30mum, a length of one side of the opening part of about 100mum, and a line thickness of about 50mum. In the thin layer having the regular grating form pattern, the opening part 4 is surrounded by the line parts 3 forming the grating form pattern. When perforation test was conducted by bringing a thermal head into contact with the plate material under the condition of 20V.1msec per dot of heating element, an opening ratio per 1mm<2> of about 40% was obtained.

This relates to the plate material used.

(Prior art) Conventional plate materials include those made by laminating biaxially stretched films such as polyester films and saran films on thin paper made of fibers such as mitsumata and kozo fibers, or mesh sheets woven from nylon filaments, etc. There is also a biaxially stretched film laminated on top.

In such plate materials, a plurality of gaps exist in the thin paper or mesh sheet due to the fibers forming them. Therefore, in a plate material made by laminating thin paper, mesh sheets, and biaxially stretched film, there is a part where the gap between the thin paper or mesh sheet faces the film surface, and a film formed around the fibers of the thin paper or mesh sheet formed around this part. A bonded portion is formed. When such a plate material is heated, shrinkage and deformation occurring in the film are prevented by the adhesive portions with the fibers. Therefore,
When the heating temperature is set appropriately, minute holes are formed in the portions of the film facing the gap. In this way, an image pattern consisting of minute holes can be formed on the plate material.

(Problems to be Solved by the Invention) However, such plate materials have the following problems. First, in a case where a biaxially stretched film is laminated on thin paper, the fibers of the thin paper are irregularly arranged, so the proportion of the film surface facing the gaps between the fibers differs in each part of the plate surface. Therefore, the densities of the holes formed are different, and the sharpness of the image periphery is reduced, making it impossible to obtain a clear printed image. Further, since the fiber density is also non-uniform, even if the same thermal energy is applied, the heating temperature differs for each part of the printing plate, and as a result, high-quality printing cannot be performed.

Next, in the case where a biaxially stretched film is laminated on a mesh sheet, the mesh sheet has a coarse mesh, so the holes formed in the film become large and the line drawing becomes thick. Furthermore, since the diameter of the fibers of the mesh sheet is large, the occurrence of white lines is unavoidable in the case of solid black images. Furthermore, heating cannot be done uniformly.

(Effects of the Invention) According to the present invention, the thin layer covering the surface of the biaxially stretched film has openings of approximately equal size formed at approximately equal density. The density becomes almost constant, and a high-quality printed image can be obtained. In addition, since the thin layer covering the surface of the biaxially stretched film has a uniform thickness, the heating temperature in each part becomes uniform, which also improves the image quality.

As described above, a printing plate having a pattern line width of about 30 μm, an opening side length of about 100 μm, and an edge thickness of about 50 μm was prepared as shown in the figure. In the figure, ■ is a polyester film, and 2 is a thin layer having a regular grid pattern printed on the surface of the film.

As a result, when the aperture ratio per 1 mm2 was measured, a value of about 40% was obtained. On the other hand, when a conventional plate material was perforated under the same conditions, the perforation test was 15% for a thin paper made of fibers such as mitsumata with a biaxially stretched film laminated, and the same perforation for the mesh sheet In the case of laminated stretched films, it was 30%.

Next, the plates made in duplicate were made using a flash plate making machine. That is, the plate material and the original were brought into close contact with each other, and flash exposure was performed using a lithographic plate making machine AP-7200. As a result, because the thermal energy was large, a large shrinkage occurred in a part of the plate material.

Therefore, a cardboard frame was attached around the plate material, the plate material was stretched uniformly, and flash exposure was performed under the same conditions as above. As a result, an aperture ratio of about 50% was obtained. This value was satisfactory in that, except for the thin layer line portion 3, the portion of the film 1 located in the opening 4 was approximately 100% perforated.
