摘要： The present disclosure provides an aluminium alloy strip for lithographic printing plate supports, which has a rolled-in surface topography on one strip surface. Further, a method is disclosed for manufacturing the aluminium alloy strip and a printing plate for lithographic printing, with a printing plate support made of aluminium alloy. The object of proposing an aluminium alloy strip for lithographic printing plate supports is that it provides a long service life in the printing process and is roughened with less charge support entry. This is achieved in that the surface of the aluminium alloy strip has a mean peak number measured perpendicular to the rolling direction of the aluminium alloy strip.
