Technical Examples
  1. Disclosed is a process for manufacturing an aluminum support for a planographic printing plate material, the process comprising the steps of electrolytically surface-roughening an aluminum plate in an electrolytic solution, employing a sinewave alternating current; and anodizing the surface-roughened aluminum plate, the electrolytically surface-roughening step comprising a first stage of electrolytically surface-roughening the aluminum plate in a first electrolytic solution containing hydrochloric acid as a main component at a current density of D1 for t1 at a quantity of electricity of Q1 and a second stage of electrolytically surface-roughening the aluminum plate in a second electrolytic solution containing hydrochloric acid as a main component at a current density of D2 for t2 at a quantity of electricity of Q2.
