Provided is a method for production of an aluminium strip for lithographic printing plate supports from an aluminium alloy including (in wt %): 0.05%≤Si≤0.25%, 0.2%≤Fe≤1%, Cu max. 400 ppm, Mn≤0.30%, 0.10%≤Mg≤0.50%, Cr≤100 ppm, Zn≤500 ppm, Ti<0.030%, the remainder aluminium and unavoidable impurities individually at most 0.03%, in total at most 0.15%. In the method, a rolling ingot is cast from an aluminium alloy, and the rolling ingot is homogenised. Further, the rolling ingot is hot rolled to a hot strip final thickness, and the hot strip is cold rolled to final thickness of between 0.1 mm and 0.5 mm. The product of the relative final thicknesses of the aluminium strip after the first and after the second cold rolling pass of the aluminium strip is 15% to 24%.
A method for production of an aluminium strip for lithographic printing plate supports from an aluminium alloy, wherein the aluminium alloy of the aluminium strip for lithographic printing plate supports comprises the following alloy constituents in % by weight:
