Abstract

PURPOSE: To obtain a support body for a lithography plate with excellent hydrophilic and water-containing properties and improved print-resisting property by applying alkali and oxide etchings to an alminum plate processed by graining and providing an anodized film thereon.
CONSTITUTION: After the alkali etching being applied to an aluminum plate processed by graining, the oxide etching is applied immediately thereto, thereby a fine sand grain structure destructed by the alkali etching being recovered or changed and water-containing and hydrophilic properties as well as the adhesiveness being improved. Next, an anodized film is provided, thereon. By this the print-resisting property is improved and the blackening phenomenon is prevented, thus a support body with the desirable whiteness is obtained. A photo-sensitive lithography plate prepared by using this support body has high sensitivity and facilitates the demarkation of the area of an image after development as well as the works for correction, elimination of image and others at preparation of the printing plate.
