摘要: A process for producing a support for planographic printing is described, which comprises electrochemically graining the surface of an aluminum plate with an electrolytic solution containing from 1,000 to 40,000 ppm of nitric acid, from 50 to 4,000 ppm of sulfuric acid group.

摘要: 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.
