ABSTRACT:
A method of making a perforated metal foil, especially for screen printing, comprises applying to a metallic surface a photosensitive layer, exposing the photosensitive layer through a screen pattern, developing the exposed photosensitive layer to remove portions surrounding dots of the photosensitive material, and electrodepositing a metal upon the surface in the region surrounding the dots. Prior to or during a galvanic deposition of the screen metal on the surface, the dots of photosensitive material are swelled so that the tendency of the perforation boundaries to be encrusted with metal is reduced and the perforations resulting in the screen have substantially the same cross sections and sizes as the dots of the photosensitive material.
