Printing method, mechanical sheet material and mounting method of printing plate material

摘要

A printing method in which printing is performed by including a mechanical sheet material between a printing plate material, which is provided with a hydrophilic layer and an image forming functional layer on the one surface of a plastic support and a back-coat layer on the other surface, and a plate drum of a printing machine, wherein the surface specific restance of the back coat layer side of said printing plate material is 1x10⁹-2x10^{13 Omegaand the surface specific resistance of the surface of said mechanical sheet material in contact with the printing plate material is 1x109}-2x10¹⁵ Omega.
