Filed: 1988-05-02
Abstract: PURPOSE:To prevent the staining of the electrophotographic planographic plating master plate by printing when the plate is subjected to a desensitization treatment by forming a printing image by a photomechanical process on the photosensitive layer of said master plate, then subjecting the printing image surface to a dry brushing treatment. CONSTITUTION:The printing image is formed by the photomechanical process on the photosensitive layer of the electrophotographic planographic plating master plate. The formation of the printing image may be executed by either of a wet developing system and dry developing system. The photosensitive layer is then subjected to a heat treatment and is then subjected to the dry brushing treatment and desensitization treatment. For example, cotton, sponge, etc., are used as the dry brushing material for dry brushing. The fine powder toners existing here and there on the surface of the photosensitive layer are thereby removed and the projections of zinc oxide are removed. Since the gaps on the surface of the photosensitive layer are thereby filled, the reactivity with the desensitization treating agent is improved and the scumming of the printed matter is prevented.
