Abstract

A process for manufacturing a strip of aluminium or an aluminium alloy for electrolytically roughened lithographic printing plates, in which the alloy is continuously cast as a strip and then rolled to final thickness, is such that the cast strip is rolled to final thickness with a thickness reduction of at least 90% without any further heating. The resultant microstructure in the region close to the surface of the strip leads to improved electrolytic etching behaviour.
