Abstract

PURPOSE: To produce the aluminium supporter having a fine and uniform disposal and a sand like surface for the printing plate, by alternating electrolysis etching of the aluminium plate in the electrolyte solution containing alkaline metal halide and hydrogen chloride.
CONSTITUTION: The aluminium plate washed with an acid is treated by alternating electrolysis etching in the electrolyte solution containing hydrogen chloride of 0.15W 0.6 mole/l and alkaline metal halide of 0.05W0.2 mole/l, for the instance, sodium chloride, with current density 5W120 A/dm2 for 10W40 s and then with anodic oxidation if necessary.
