、紫外 。Plate making of these photosensitive resin plate materials is generally performed as follows. That is, a negative silver salt film obtained by pupil shadowing a printing original using a plate-making camera and development, or a positive film obtained by reversing this film, is brought into close contact with the photosensitive resin layer and exposed to ultraviolet light. At this time, the area where the silver image is formed on the silver halide film is exposed to ultraviolet light.

システムも開発されている。A printing plate is produced by visualizing this in a developing process. Recently, a system has been developed in which, without using a plate-making camera, a document is input into a computer and converted into an electrical signal, which is then scanned with a laser to draw directly on a silver halide film and then developed.
しかしながら、これらの方法は、高度の解像力を得るた
めには優れているが、銀塩フィルムを使用するために、
複雑な現像工程が必要であり、機器や設備も高価であり
、処理時間も長いという問題がある。However, although these methods are excellent for obtaining high resolution, they are difficult to use because they use silver halide films.
There are problems in that a complicated developing process is required, the equipment and equipment are expensive, and the processing time is long.
［発明が解決しようとする課題］

。[Problems to be Solved by the Invention] In the conventional silver halide photography method, an original film for plate making was produced using expensive equipment and skilled techniques. For this reason, there has been a strong desire to develop a method for easily producing original drawings, especially a method for directly producing original drawings for plate making using electrical signals from computers.
本発明は、かかる従来技術の現状に鑑み０１案されたも
ので、その目的は高品位で解像力の高い感光性印刷版材
製版用原図を簡単にかつ低コストで得ることにある。The present invention has been devised in view of the current state of the prior art, and its purpose is to easily obtain a high-quality, high-resolution plate-making original for a photosensitive printing plate material at a low cost.

ングすることも有効である。The ultraviolet-transparent sheet used in the present invention includes plastic films such as polyester film, polypropylene film, polyethylene film, polyvinyl chloride film, acetate film, polystyrene film, polycarbonate film, polyamide film, polyimide film, and polyphenylene sulfide film, and sulfuric acid film. Examples include paper that has a certain degree of ultraviolet transmittance, such as paper, and cloth obtained by weaving transparent fibers. Plastic films are particularly preferred from the viewpoints of transparency, smoothness, appearance, and toughness, and among these, polyester films are particularly preferred from the viewpoints of dimensional stability. Matting the surface of the plastic film improves the adhesion of transfer ink and toner used for word processor printouts, so it is preferable to the extent that a decrease in ultraviolet transmittance does not pose a practical problem. It is also effective to coat the surface of the film with a layer that is compatible with transfer ink and toner.

囲におることが好ましい。The thickness of the ultraviolet-transparent sheet is not particularly limited, but if it is too thin, it may be torn due to getting caught in a roller when printing out an image using a word processor. On the other hand, if it is too thick, the transmittance of ultraviolet rays during exposure often decreases. For these reasons, the thickness of the ultraviolet-transparent sheet is preferably in the range of 50 to 500 microns.

。When the obtained printing plate is used for direct printing such as ordinary letterpress printing or intaglio printing, the printed out light-shielding image may be a normal image. However, offset printing, such as offset lithographic printing, offset letterpress printing, offset gravure printing, and pad printing, involves transferring ink from a printing plate to a blanket, rubber roll, or silicone rubber pad, and then retransferring this ink to the substrate for printing. In this case, the shaded image needs to be an inverted image. Among recently developed word processors, there are models that can print out a reverse image (mirror image). An example of such a model is "Report JWI OOE" manufactured by Toshiba Corporation.If you use this model, after inputting normally, if you select the mirror image printing mode when printing out, a reverse image (mirror image) will be printed. ) can be drawn on a UV-transparent sheet.

フが形成された。This negative original image film was vacuum-adhered to the photosensitive layer surface of a photosensitive resin letterpress plate called "Trelief" WF-70BS (manufactured by Toshiku Co., Ltd.) so that the surface on which the light-shielding portion was formed was in contact. Next, exposure was carried out for 2 minutes using an ultra-high pressure mercury lamp to cause a photopolymerization reaction to occur in the photosensitive layer corresponding to the light-transmitting portion corresponding to the input image. Thereafter, when the image was developed using a brush developer with running water, a relief corresponding to the word processor input image was formed.

写が向上することなどに起因している。This is because it can be easily entered into a word processor, the use of a pigment-based transfer ink layer and overlapping techniques can produce images that sufficiently block ultraviolet rays, and the use of a film with a slightly matte surface. This is due to improved ink transfer.
