Abstract (en)
Aluminium web (1) is passed through a first bath (2) containing phosphate ions and a socond bath (3) containing sulphate ions and is anodised by passing alternating current between electrodes (4, 5) immersed one in each bath. The product is especially suitable for use as a base for a presensitised lithographic printing plate.
