The present invention relates to a method for forming a halftone image on a lithographic stripping film (silver salt gelatin photosensitive material) using the lithographic stripping film. In the correction of half-tone (half-tone) images such as color characters and color bands in photoengraving such as gravure photoengraving, there is a great demand for stripping films that can easily form half-tone (half-tone) images. However, stripping film is only available in the lithographic format, so to correct halftone (halftone) images such as color characters and color bands, it is necessary to recreate the exposure negative and re-expose it to continuous tone film. It becomes necessary. For this reason, there has been an inconvenience that work losses and material losses associated with correction of halftone images such as color characters and color bands become extremely large. The present invention has been made in view of the above circumstances, and involves performing exposure, development, reversal development, fixing, etc. on a lithium-type stripping film (silver salt gelatin photosensitive material) to form a gelatin layer. After the image area is formed on the lithographic stripping film, the image area made of the gelatin layer is dyed using a dye that has a light-shielding property in the sensitive wavelength range of the desired photosensitive material. This is a method of forming a halftone image on a lithographic stripping film, which is characterized by forming an image. The present invention will be described in detail below with reference to the drawings. FIG. 1 is a sectional view showing the general structure of a lithographic stripping film, which is composed of an emulsion layer 1, a permanent support 2, a release layer 3, a temporary support 4 and a backing layer 5. Squirrel-type photosensitive emulsions are designed to create transparent areas with high density and low fog, and have characteristics that make it easy to reproduce only two gradations of white and black, such as letters and cutouts. ing. and,
Although fringes are less likely to occur on the image lines and it has excellent resolution, it also has a super-contrast gamma value, so it also has the characteristic that intermediate density recording does not form gradations. A positive original 6 is placed on the lithographic stripping film 7 having the above-mentioned characteristics as shown in FIG. 7. Apply the necessary exposure. A latent image 8 is formed on the exposed portion of the emulsion layer 1 of the lithographic stripping film 7. Next, the lithographic stripping film 7 on which the latent image 8 has been formed is sequentially subjected to development, stoppage, reversal development, and film peeling treatment by a conventionally commonly used method. The lithium-shaped stripping film after development and peeling is shown in FIG. 2, respectively. 9 indicates a negative silver image area (silver halide 11+gelatin), and 10 indicates a positive silver image area (silver halide 12+gelatin). The reversal development here means a development process for forming the positive silver image area 10, and does not include the second exposure step and second development step after bleaching (desilvering) that are normally performed. shall be taken as a thing. Therefore, silver halide 12 is present in the positive silver image area 10 formed after reversal development. Next, the lithium stripping film on which the positive silver image area 10 has been formed in the above process is washed with water to remove the softened negative silver image area 9, and then subjected to a fixing process to remove the softened negative silver image area 9. Silver halide 12 is precipitated to form an image area 13 made of a gelatin layer on a lithographic stripping film. This situation is shown in Figure 2 (d). The lithographic stripping film on which the image area 13 made of a gelatin layer is formed is then subjected to a dyeing process.
The dye used in this dyeing process has a desired light-shielding property, and it is necessary to dye only the image area 13 made of the gelatin layer.
shall not be dyed. Therefore, here
It is known that dyeing can be carried out using dyes such as Safranine A and Chrysoidine 3R. We prepare a variety of such dyes with different concentrations,
By dyeing only the image area 13 made of the gelatin layer, a halftone image 14 having a desired middle density is formed on the lithographic stripping film. A lithographic stripping film having a halftone image 14 obtained in the above manner is shown in FIG. 2(E). The thus obtained squirrel-shaped stripping film having the halftone image 14 is prepared by inserting a knife around the required area, rolling up one end, peeling off the film from the release layer 3, and following the layout instructions. Then, the halftone image is edited, a photographic original plate for plate making is constructed, and printing and inlaying are performed. According to the present invention, it is possible to easily form a halftone image even when using a lithographic stripping film, which is extremely difficult to reproduce halftone images. Therefore, when it is necessary to correct the halftone image on the photo plate for platemaking during the photolithography process, by using the lithographic stripping film, it is easy to partially correct the halftone image that needs to be corrected. This facilitates the simplification of the partial correction process and the saving of plate-making materials. Further, according to the present invention, it is possible to provide a lithium-type stripping film having halftone images of various hues, so that it can be used as a substitute for a color band portion when assembling a duplex. An embodiment of the present invention will be shown below. <Example> A positive original was brought into close contact with a squirrel-type stripping film (OLS-140A) manufactured by Konishiroku Photo Industry Co., Ltd.
Exposure was performed for 10 seconds using a flat printer. Next, it was developed (20° C., 3 minutes) using a developer (LD-322) manufactured by Fuji Photo Film Co., Ltd. to form a negative silver image area 9 in the exposed area. Next, negative silver image section 9
After immersing the lithium-shaped stripping film in a stop solution for 15 seconds to temporarily stop the development process, perform reversal development and film removal using a reversal development and film stripping solution with the following formulation. Ta.

An image area 13 made of a gelatin layer was formed on the lithographic stripping film. Next, three lithium-shaped stripping films each having an image area 13 made of a gelatin layer obtained as described above are prepared, and the following three types of stripping films are applied to the image area 13 of each lithium-type stripping film. Halftone images 14 with the following densities were formed on each lithium stripping film by dyeing with an acid dye (manufactured by Chugai Kasei Co., Ltd.).
