ABSTRACT:
A process for electrochemically modifying support materials of aluminum or aluminum alloys, which have been grained in a multi-stage process is disclosed. These support materials can be used in the production of offset printing plates. The support material is mechanically grained in a stage I, subjected to an intermediate treatment in a stage II, electrochemically grained in a stage III, subjected to an intermediate treatment in a stage IV and anodically oxidized in a stage V. The intermediate treatment in stages II and/or IV are carried out by an electrochemical process using a direct current. The anodizing stage may be followed by a hydrophilizing stage VI.
