摘要：
In a process for producing an aluminum support of a lithographic printing plate, the desired aluminum support is produced by imparting fine asperities to an aluminum plate and then roughening it electrochemically in an acidic aqueous solution. The roughened aluminum plate may be electropolished or chemically etched.
