PURPOSE:To reduce the electric resistance, and especially, to make a punched picture easy to see without using a surface visualizing layer, by making a punching film of an electronic recording stencil paper contain a photoconductive material, and executing the punching operation, irradiating a light beam. CONSTITUTION:A stencil paper for the electronic recording photoengraving is manufactured by applying, drying, etc. a solution containing a mixture of 1:3-4:1 weight ratio of photoconductive ZnO powder and a binder, on a conductive pasteboard which has been obtained by applying carbon black and a bonding material onto super quality paper, etc. This stencil paper is set, for instance, to a drum 1, a light bean of a halogen lamp 2, etc. is condensed by a lens 3, is irradiated to the stencil paper, and punching is executed by a stylus (electrode needle) 5 which is controlled by an electric power source 4. In this way, it is possible to obtain a stencil paper by which black of a conductive layer is easy to see, a picture becomes clear, and the printing resistance is satisfactory. |
