必要がある。 Japanese Patent Publication No. 54-29127 is a conventional endless plate making method. This endless plate-making method has been attracting attention in the printing industry since before it was filed as a plate-making technology that can produce seamless plates that do not require operator skill, correction, or reprinting of resist images obtained by printing. Ta. This is because the exact same plate-making method was used in the sales brochure (title: LTT
- system), and the American industry magazine Gravure, which carried a release advertisement article by Henry P. Cohn Associates New York, an American sales partner, in 1971. be. Regardless of whether or not there are grounds for invalidating the patent for the plate-making method of 1977-29127, research into the technical effects of the plate-making method has revealed that the plate-making method has the following problems. I found that something remained unresolved. First of all, the light-shielding tape is 10
Since a film with a width of about mm is used, if the endless joint of the original film is a curve with a width exceeding 10 mm, a mask using light-shielding tape is useless. Second, in a multi-sided printing machine, a plurality of square original films, each of which is generally about 300 mm in size, are joined together, and as a result, the joints exist along the X and Y axes. On the other hand, the thickness of the light-shielding tape currently available on the market is 4μ, so the thickness of the overlapping part of the light-shielding tape at the joint where the X-axis and Y-axis intersect is 8μ. At the edges, the original film is at least separated from the photosensitive film.
8μ is raised, which causes the printed image to become blurred, requiring correction or reprinting. Thirdly, it is important to attach the light-shielding tape to the photoresist film without any wrinkles in order to prevent the printed image from becoming blurred, but the light-shielding tape should be pasted along the predetermined joint line without wrinkles over a long dimension. In particular, the current situation requires the skill and time of the operator. This is the cause of the first problem mentioned above. That is, as the width of the tape increases, it becomes more difficult to apply the tape without leaving air in it or causing wrinkles, making it unsuitable for endless plate-making methods in which the joints form large curves. The fourth point is that light-shielding tapes are more expensive than light-shielding paints, and must be taken into consideration from the point of view of energy conservation.

貼着して塗り幅を小さくしても良い。 As shown in Fig. 1, a first solvent that does not attack the photosensitive coating is dissolved in the part that will become the endless joint of the original film on the unexposed photosensitive coating film formed on the cylinder 1, which is the printing plate base material. A first light-shielding coating film 2 made of a first light-shielding paint is formed, and after drying, one end of the original film 3 is overlapped with the first light-shielding coating film 2, and baking is started from one end of the first light-shielding coating film 2. Then, as shown in FIG. A second solvent that does not attack the photosensitive coating film, which is different from the first solvent, is applied over the required width of the first end of the first light-shielding coating film 2 that has already been baked so that it is partially overcoated on the first light-shielding coating film 2 during the baking process. A second light-shielding coating film 4 is formed of a second light-shielding paint that is soluble in water and does not cause deterioration even when overcoated on the first light-shielding coating film 2, and after drying, the first light-shielding coating film 4 is coated with a first solvent. The coating film 2 and the overlapping portion 4a of the second light-shielding coating film are solublely removed, followed by baking as shown in FIG. 3, and after the baking is completed, the second light-shielding coating film 4 is solublely removed using a second solvent. After that, a treatment process for corrosion is performed. This plate-making method can be applied not only to gravure printing but also to planography and photoletter printing. The photosensitive liquid for forming the photosensitive coating film is not particularly limited. As a combination of the first light-shielding paint forming the first light-shielding coating film 2 and the second light-shielding paint forming the second light-shielding coating film 4, water-based paint and oil-based paint are most preferable. Emulsion paints can also be used as light-shielding paints, since some are water-based and others are oil-based depending on their blending ratio. When combining water-based paint and oil-based paint, it is natural to use water as the first solvent, but also as the second solvent.
Since isopropyl alcohol is the best solvent that does not attack the photosensitive film, it is better to select an oil-based paint that is soluble in this solvent. According to an experiment in which the water-based paint, which is the first light-shielding paint, was washed with water, only the portion 4a overly coated with the water-based paint of the oil-based paint, which is the second light-shielding paint, was successfully peeled off together with the water-based paint in powder form. After removing the water-based paint, the film is washed with normal hexane, and then baking is continued. Poor quality oil-based paints, such as those containing a large amount of extender pigments and those using petroleum as a solvent, are preferable as the second light-shielding paint because they have low solvent resistance and will peel off slightly after painting. Furthermore, if silicone or the like is added to the water-based paint, the overcoated areas of the oil-based paint will pop off in the form of droplets due to surface tension, so if this is removed skillfully, good separation is possible. Other combinations include water-based enamel and oil-based enamel, water-based varnish and short oil-based varnish sold under the trade name Gold Size,
Oil-based or volatile asphalt varnishes may also be used. In short, the first light-shielding paint and the second light-shielding paint only need to be easily soluble in different solvents. For example, it may be a combination of oil-based paint and oil-based paint. In particular, the combination of this example is limited in that the oil-based paint that becomes the second light-shielding paint is coated with a first solvent that solublely removes the coating film 2 of the oil-based paint that becomes the first light-shielding paint, so that only the overcoated portion 4a is undercoated. It is necessary to select a material that peels off easily due to the presence of , and it is better to choose a material that does not require durability and dries quickly. Furthermore, the first light-shielding paint and the second light-shielding paint need to be selected in such a way that the solubility of the first light-shielding paint in the first solvent does not change when the first light-shielding paint is overcoated. As a coating method, a spray method, a roller coating method, etc. are preferable. Incidentally, if necessary, masks may be attached to both ends of the original film to reduce the coating width.

光テープ代を節約できるという効果を有する。 The endless plate-making method of this invention as explained above is an extremely sophisticated method that does not require the skill and correction of the operator or any reprints on the printing plate base material, which are the technical effects of the plate-making method of Japanese Patent Publication No. 54-29127. Not only can endless plate making be achieved in exactly the same way, but in addition, this plate making method has the excellent effect of solving all the problems that have remained unsolved since then. That is, as a unique effect of the endless plate making method of this invention, first of all, even if the endless seam of the original film is a curved line spanning a large width such as 50 mm or 200 mm, it does not require the use of light-shielding tape and is light-shielding. Since it uses paint, endless plate making is possible, and secondly, the thickness of the overcoating of the light-shielding paint is much greater than that of the light-shielding tape at the part where the endless joint intersects the X and Y axes. It is small, so the printed image in this area will not be blurred, and thirdly, since no light-shielding tape is used, there is no need for skill or time to apply the light-shielding tape, and when applying the light-shielding tape, It is possible to avoid blurring of the printed image due to unnoticed wrinkles, and the fourth advantage is that the cost of light-shielding tape can be saved.
