摘要:
A printing method in which printing is performed by including a sheet material between a printing plate, 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 resistance of the back-coat layer side of said printing plate is 1 x 10 9 - 2 x 10 13 Ω and the surface specific resistance of the surface of said sheet material in contact with the printing plate is 1 x 10 8 - 2 x 10 15 Ω.
摘要:
Disclosed is a printing method comprising the steps of mounting an underlay sheet on a plate cylinder of a printing press, and providing, on the underlay sheet, a printing plate material comprising a plastic sheet support, and provided thereon, a hydrophilic layer, an image formation layer and a backing layer, the backing layer being provided on the side of the support opposite the image formation layer, so that the backing layer side surface of the printing plate material contacts the underlay sheet surface, wherein a coefficient of dynamic friction of the backing layer side surface of the printing plate material to the underlay sheet surface is from 0.1 to 0.5.
