    摘要: A rotating preparatory abrasion roller finely abrades the surface of a web, which is to be a support of a lithographic plate, in preparatory abrading prior to main graining for graining the surface of the web. The preparatory abrasion roller, which is arranged against one surface of the running web, is pressed into an interval between a pair of supporting rollers, which are arranged at a predetermined interval against the other surface of the web. Consequently, the surface of the web is finely abraded in contact with a relatively large area on the surface of the preparatory abrasion roller in the state wherein the web laps with the part of the preparatory abrasion roller.

    摘要: A support for a planographic printing plate support in which variations in the quality of the material of the aluminum support are reduced to thereby improve the yield in an electrolytic graining treatment and which is excellent in susceptibility to graining, has no stripe irregularities, and excellent appearance, and a method for producing such a planographic printing plate. An aluminum plate material is formed through a twin-roller continuous casting apparatus and subjected to cold rolling. Successively, the plate is subjected to heat treatment so as to form a surface portion of a depth of at least 15 .mu.m in the thickness direction having no recrystallization in the surface layer. If necessary, the plate may be subjected to cold rolling again as final rolling. Thereafter, the plate is subjected to correction.
