Abstract: A photosensitive resin printing original plate is disclosed in which a side surface light-blocking layer does not peel off from a metal support during handling of the printing original plate, and which enables efficient production of the side surface light-blocking layer. A water-developable photosensitive resin printing original plate, includes at least: a support; and a photosensitive resin layer arranged on the support, in which a peripheral side surface of the water-developable photosensitive resin printing original plate is covered with a light-blocking layer; the light-blocking layer contains carbon black and a vinyl polymer at a mass ratio of 80/20 to 30/70; and the vinyl polymer is an alcohol-soluble vinyl polymer containing 25 to 65 mol % of a hydroxyl group with respect to a constituent monomer unit in a molecule (in the case of being chemically modified, a constituent monomer unit after the modification).

Abstract: A method includes (i) preparing a printing original plate sheet having an uncured photosensitive resin layer on a surface thereof, wherein compressive strength of the uncured photosensitive resin layer at 25° C. is 1.0 to 3.0 kgf/cm2; (ii) mounting the printing original plate sheet around a cylindrical support in such a manner that a starting terminal of the mounting and an ending terminal of the mounting are overlapped; and (iii) applying pressure to the overlapped area of the starting terminal of the mounting and the ending terminal of the mounting at a temperature range of 10 to 40° C. so as to pressure-bond the overlapped area. The method may further include, after the step (iii), a step (iv) for photo-curing the uncured photosensitive resin layer and may further comprise, after the step (iv), a step (v) for grinding, abrading and/or machining the overlapped area.
Abstract translation: 一种方法包括（i）在其表面上制备具有未固化的感光性树脂层的印刷原版片，其中未固化的感光性树脂层在25℃下的抗压强度为1.0〜3.0kgf / cm 2; （ii）将打印原稿片安装在圆筒形支架上，使得安装件的起始端和安装件的端子端部重叠; 和（iii）在10至40℃的温度范围内对安装件的安装件的起始端子和终端的重叠区域施加压力，以便压合重叠区域。 该方法还可以包括在步骤（iii）之后，对未固化的感光性树脂层进行光固化的步骤（iv），并且在步骤（iv）之后还可以包括用于研磨，研磨和/ 或加工重叠区域。
