Abstract (en)
[origin: US4800950A] A substrate for a lithographic printing plate is made of a rolled aluminum alloy sheet of following composition: 0.8 to 2.0% Fe, up to 0.8% Si and up to 1.0% Mn, such that the sum of the Si and Mn contents lies between 0.3 and 1.3%, up to 0.3% Cu, up to 0.8% Mg, up to 2.0% Zn and 0.3% each of other constituents in total up to 1.0%, rest aluminum. A process for manufacturing such a substrate is such that this composition is cast as a 5 to 12 mm thick strip then fabricated to a 0.03 to 0.6 mm thick rolled sheet.
