PLANOGRAPHIC PRINTING PLATE MATERIAL, PRINTING PLATE OBTAINED BY USING THE SAME AND PRINTING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a planographic printing plate material which has improved initial ink receptivity, printing wear after a long-term storage and out-of-color registration (out of registration) resistance in printing, and to provide a printing plate obtained by using the same and a printing method.

SOLUTION: The planographic printing plate material including at least one hydrophilic layer, a silver halide emulsion layer, a physical developing nucleus layer and a backing layer on a plastic support, is characterised in that a surface on the backing layer provided side has a surface specific resistance of 1×1011-2×1013Ω and a coefficient of dynamic friction of 0.15-0.6 to stainless steel.
