摘要： PURPOSE:To enable reduction treatment wide in reducing extent without increasing an amt. of silver applied by forming a positive type photosensitive resin layer on the surface of a transparent support bearing a transparent original silver image, exposing it form the reverse side of the support, and reducing the developed image. CONSTITUTION:A positive type photosensitive resin layer 2 is formed on a transparent image 1 obtained by using a plate making photosensitive material, and the layer 2 is uniformly exposed from the side of a transparent support 11 in the arrow direction, as shown in the figure. At that time, the photosensitive resin 22 located on the silver image part 122 is not exposed, and only the resin 21 located on the nonimage parts 123 are exposed. When the resin layer 2 is developed, only the resin layers 21 of the exposed parts are removed, and the resin layer 3 on the silver image part 122 remains as it is. When this original is reduced, the silver image 122 undergoes action of the reducing soln. from the side faces. Therefore, the image can be reduced while lowering of the image density is controlled.
摘要翻译：目的：在不增加放射性的情况下，减少治疗范围。通过在具有透明原始银图像的透明支撑体的表面上形成正型感光性树脂层，将其从支撑体的背面暴露，并且减少显影图像而施加的银。构成：如图所示，在通过使用制版感光材料获得的透明图像1上形成正型感光性树脂层2，并且层2从透明支撑体11的一侧沿箭头方向均匀地露出。此时，位于银图像部122上的感光性树脂22不露出，只露出位于非图像部123上的树脂21。当树脂层2显影时，仅去除暴露部分的树脂层21，并且银图像部分122上的树脂层3保持原状。当原稿减少时，银图像122经历还原溶胶的作用。从侧面。因此，可以降低图像，同时降低图像浓度。

摘要： PURPOSE: To obtain an image small in coloring due to remaining dyes after development and high in contrast, by adding an oxonol dye.
CONSTITUTION: An aluminum support grained in advance and anodized is coated with a layer of a positive type photosensitive compsn. prepd. by adding to a photosolubilizable compsn. consisting of an o-quinonediazide compd. and a phenolic resin an oxonol dye represented by the general formula in which R
1 and R
2 are each optionally substd. monovalent group selected from aryl, lower alkyl, and alkoxycarbonyl, and they can be different from each other, and n is 1 or 2. After the layer is exposed, it is developed with an aq. alkaline soln. The o- quinonediazide compd. contained in the positive type photosensitive compsn. is photodecomposed by the exposure to produce an acidic product, and a visible image having sufficient contrast is obtained by change of tone caused by mutual action of said acidic product and the oxonol dye. The use of said dye reduces residual coloring indifferent of using a fresh or fatigued developing soln. and causes no uneven development.

摘要： PURPOSE:To prevent the production of insoluble matter during developing and make possible developing of a large amount of positive type photosensitive lithographic printing plates by using the aqueous solution of the alkali metal silicate containing the specific amount of potassium as a developing solution (replenisher). CONSTITUTION:The developing solution (replenisher) in which potassium occupy more than 20% (gram atom equivalent) of the total alkali metals contained out thereof is used as the aqueous alkali metal silicate developing solution (replenisher) used in developing of the positive type photosensitive lithographic printing plate (PS plate) using o-quinone diazide compound as its photosensitive agent. Potassium hydroxide, potassium borate, potassium pyrophosphate, etc. are used as the abovememntioned potassium sources (the use of potassium chloride, potassium nitrate, etc. is almost non-effectual). The SiO2(gram molecule)/M(gram atom ratio of alkali metals) ratios are preferably about 0.5 to 0.75 with the developing solution and about 0.25 to 0.75 with the replenisher. The abovementioned developing solution (replenisher) is particularly highly effectice for the positive type PS plate using anodized Al plate as its substrate.

摘要： PURPOSE:To expose the unnecessary parts of an image and to erase easily said parts by displaying the visible print-out image obtd. by exposing an image with a positive type PS plate on an image receiving tube of a video device, inputting said image to an X-Y plotter and irradiating active rays thereto through an optical fiber. CONSTITUTION:The visible print-out image obtd. by exposing an image with a positive type PS plate 10 is displayed on an image receiving tube 22 of a video device 20 and the unnecessary images 11', 12', 13' are indicated by a light pen 30. The information on the indicated position is inputted to an X-Y plotter 40 and the head 41 of the X-Y plotter is disposed to the corresponding position of the plate 10 exposed with the image. Active rays are irradiated from the tip of an optical fiber 51 attached to the head 41 to expose the unnecessary images 11, 12, 13 and thereafter the positive PS plate is developed. The unnecessary parts on the print-out image, for example, the dust sticking to the glass of a vacuum printing frame, film edge, register mark and the other parts which are left without being exposed owing to the presence of foreign matter are erased by such operation. The stain-free printed matter having good quality is thus obtd.

摘要： PURPOSE: To easily form a printing plate having an unnecessary part erased by irradiating the unexposed part to be erased in a positive type photosensitive lithographic plate imagewise exposed, with an active ray guided through optical fibers, and then developing it.
CONSTITUTION: A positive type photosensitive layer made of a mixture of, e.g. an o-naphthoquinonediazide compd., a novolak type phenolic resin, a dye, etc. is formed on a support having a hydrophilic surface, e.g. an anodized aluminum plate, to form a positive type lithographic plate (a positive type PS plate), and it is imagewise exposed with an active ray. Then, unnecessary unexposed parts caused by dust, film edges, etc. are exposed to the active ray having about 1W 5mm light diameter guided through optical fibers, and it is developed by the ordinary method. At that time, it is desirable to use a device obtained by connecting one end of an industrial fiber scope with the lamp chamber of a vacuum printing frame and the other end with an optical fiber pen.
