Title: Lithographic original plate
Inventor: MARUYAMA HITOSHI
IPC: G03G5/05
Filed: 1982-03-23
Abstract: PURPOSE:To enhance the water resistance and printability of a lithographic original plate by providing a modified polyvinyl alcohol layer containing silicon on a supporter. CONSTITUTION:A modified polyvinyl alcohol containing silicon is obtained by a method in which silicon is introduced into a modified polyvinyl acetate with carboxylic or hydroxyl group or a polyvinyl alcohol by using a silylizing agent or subjecting a copolymer of vinyl ester and an olefinic unsaturated monomer containing silicon to saponification. A pigment particle of zinc oxide, cadmium sulfide, titanium oxide, etc., having a photo-conductive layer, is dispersed into the modified polyvinyl alcohol aqueous solution, and the dispersion is laminated on a supporter to obtain an original plate. The original plate is subjected to desensitization treatment in order to keep it in lipophilic state. Thus, the water resistance is raised because oil ink is adhered only to lipophilic sections.

Filed: 1984-03-12
Abstract: PURPOSE:To attain ease of operation of the operator and to miniaturize the system scale by allowing the titled device to cope with the conversion from a positive picture to a positive picture, from a positive original to an inter negative original, from a negative original to a positive picture and also from a negative original to an intermediate negative original. CONSTITUTION:A coefficient used for the operation in signal processing sections 2, 3, a color processing section 4, and picture output sections 5, 6 and a table data used for the conversion are transmitted externally with the operation from a mini computer 10. Further, the coefficient and data handled by the color processing section 4 are changed manually by the operator. A picture signal obtained from a positive original is converted into a positive density signal by a positive original input signal processing section 2 and a picture signal obtained from a negative original is converted at the negative original input signal processing section 3 respectively. When a positive picture is desired on an output sensitive material, an output signal from the color processing section 4 is inputted to the positive picture output section 5 and when a negative picture is desired, the output signal from the color processing section 4 is inputted to the negative picture output section 6 respectively. Thus, the color processing of a density signal as to all combinations of kinds of negative and positive original and reproduced picture is processed by the same color processing section 4.
