Abstract

A photographic method of printing a screen structure for a cathode ray tube, having a faceplate and a perforated mask remote from the faceplate, depositing a photosensitive coating on the faceplate, exposing or impressing such a coating, through of the openings made in said mask, to the light coming from a light source with a small area and then revealing said exposed or impressed coating, said method characterized in that the photosensitive coating is exposed separately to at least two sources of small area light, the larger of said two light sources having an equivalent circular diameter of about 4 to 5 mm, and the smaller of said two sources having an equivalent circular diameter of about 2 to 3 mm.
