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.

The object of providing a method for conditioning a working roll with which the material properties of a working roll can be set in a process-reliable and uniform manner is achieved by a method in which a roll and at least one pressure tool are rotated relative to each other, in which pressure is applied locally to the roll by means of the at least one pressure tool, comprising at least one pressure element, via the at least one pressure element, and in which a deep rolling process is carried out.
