Abstract

Some improvements in the manufacture of lithographic plates, for the manufacture of an unsealed base plate, suitable for the manufacture of lithographic printing plates, characterized in that the aluminum or aluminum alloy sheet is subjected to a cleaning operation and then to an anodizing using an electrolyte comprising sulfuric acid, to form a porous anodic oxide layer and treating the anodic oxide layer with phosphoric acid in aqueous solution.
