Abstract (en)
Disclosed is a method for the production of an aluminium alloy support for a digitally imageable lithographic printing plate, comprising forming a support by carrying out the subsequent steps of: continuously casting a molten aluminium alloy to form a strip having a thickness less than 30 mm; cold rolling said strip to form said support; optionally a heat treatment step of said support; correction of the support; and mildly graining said support; followed by providing a digitally imageable coating on said support, whereby said printing plate is obtained, characterized in that said aluminium alloy composition contains an iron amount between 0.15% by weight and 0.50% by weight; a silicon amount between 0.05% by weight and 0.20% by weight; and a copper amount between 0.005% by weight and 0.040% by weight.
