    摘要： 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/dm2 of 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.

    摘要： A support made of an aluminum plate for a planographic printing plate is electrochemically roughened in an acidic aqueous solution in an electrolytic apparatus with plural cathodes and anodes arranged alternately on one side of the plate by applying a DC voltage. A soft starting zone which comprises at least one electrode connected to an electric power supply, which is separate from a main electric source, is provided. A current density of 0.01 to 100 A/dm2, which is lower than the current density used in any subsequent main roughening, is provided in the soft starting zone.
