ABSTRACT:
A process for manufacturing an aluminum support for a planographic printing plate material, the process containing the steps of: (a) electrolytically surface-roughening an aluminum plate in an electrolyte solution containing hydrochloric acid as a main component; and (b) anodizing the surface-roughened aluminum plate, wherein the step (a) contains: (i) a first stage which surface-roughens the aluminum plate employing a sine-wave alternating current; and (ii) a second stage which surface-roughens the aluminum plate employing a controlled sine-wave alternating current using a thyristor so that a current flow starts at a phase angle of 60 to 120 degree of an alternating current cycle.
