    摘要: A lithographic printing plate having an average curvature in a rolling direction of 1.5X10 -3 mm -1 or less, a curvature distribution in a crosswise direction of 1.5X10 -3 mm -1 or less, and a curvature in a direction perpendicular to said rolling direction of 1.0X10 -3 mm -1 or less and a method for producing the printing plate are disclosed. A method for producing a support for a lithographic printing plate is also disclosed, which comprises roughening a surface of an aluminum web having a center line average surface roughness of 0.15 to 0.35 µm and a maximum surface roughness of 1 to 3.5 µm by at least one of mechanical surface roughening, chemical etching and electrochemical surface roughening, and then applying anodization thereto.
