Abstract

Aluminium (1) is immersed in a bath (2) containing phosphate ions before anodising in a bath (3) containing sulphate ions. When the substrate is aluminium foil in web form, preferably the phosphate bath serves as a liquid junction cell by which the anodising current is introduced into the web. Aluminium foil or sheet so processed is especially suitable as a base for a presensitised lithographic printing plate.
