(57) Abstract: A support for a lithographic printing plate having good sponge slipperiness and a method for producing the same. SOLUTION: An aluminum plate that has been roughened and anodized has a center line average roughness Ra of 0. 2 to 1.2 μm, and the average inclination angle θa is 0.12 It is a support for a lithographic printing plate, characterized in that it is 0.15 rad, and the amount of aluminum dissolved is 2 by chemical etching after mechanically roughening the aluminum plate. The method for producing a lithographic printing plate support is characterized in that it is carried out at 0 to 50 g / m 2 . |
