ABSTRACT:
Direct contact printing methods and apparatuses are disclosed for applying screen elements to cathode ray tube (CRT) faceplates. A black-surround, or grille, is first applied to the faceplate, followed by deposition of light-emissive phosphors thereon. Means for repeatable positioning of the screen elements on the faceplate, means for registration of the screen elements with each other, and means for maintaining screen element shape and size are also disclosed. Effective pivot axes for the collector are arranged to lie in the plane of the printing substrates.
