ABSTRACT:
A method of forming a roll for embossing aluminum sheet, and the associated roll, the method comprising subjecting a surface of a steel roll to at least the steps of, in order: blasting treatment, electrolytic treatment with 1,000 to 20,000 C/dm2of electricity in which the steel roll is used as the anode, and chromium plating treatment. An aluminum sheet embossing roll produced by the method of the present invention has on the surface thereof peaks, or asperities, which are of uniform height and very numerous. As a result, aluminum sheets obtained using such a roll, when employed as lithographic printing plate supports, have excellent printing characteristics, particularly a long press life and a high sensitivity.
