Abstract

A process for producing an aluminum support for a lithographic printing plate, which comprises roughening an aluminum plate surface by a liquid honing process to form a first grain thereon and then modifying the first grain by a brush grinding process, and optionally, subjecting the modified surface to electrochemical graining. A printing plate using the aluminum support is excellent in printing durability and gives little background contamination.
