摘要

The litho sheet for the electrochemical roughening, comprises a rolled aluminum alloy, where a sheet surface has a topography with: a maximum peak height R pand/or S pof less than 1.0 mu m; and a reduced peak height R p kand/or S p kof less than 0.37 mu m. A thickness of the litho sheet is 0.5-0.1 mm. Independent claims are included for: (1) a method for producing a litho sheet; and (2) printing plate supports.
