PROBLEM TO BE SOLVED: To enable easy mounting of a plate material even in an automatic plate supply printing system capable of surely preventing stretching and a positional deviation of a lithographic printing plate on a plate cylinder of a printer, being applied to printing of multicolor many prints with a material except a metal used as a support and satisfying a printing performance and durability under severe using conditions. SOLUTION: A lithographic printing original plate comprises at least an image acceptive layer on a water resistant support. The original plate further comprises an adhesive layer having a static frictional coefficient of 0.2 or more, an adhesive force of 2 to 150 kgf/cm2 and a release force of less than 40 fg/cm and provided on a rear surface thereof. In this plate, the adhesive layer is closely contacted with the plate cylinder of a lithographic printer at a printing time. |
