ABSTRACT:
A method for manufacturing an element with a conducting surface and a pattern of insulating spots to be used as a die for the electrolytic production of sieves for screeen printing. The method starts from a conducting surface consisting of or coated with a material that either possesses insulating properties or can be rendered insulating after heating, the surface being patternwise irradiated with short pulses of a high-energy radiation, such that countersunk spots of an insulating substance are obtained on the surface.
