Screen Registration Device

US Patent:
4440080, Apr 3, 1984
Filed:
Dec 21, 1981
Appl. No.:
6/332750
Inventors:
Joseph G. Lyall - Lancaster PA
Assignee:
Armstrong World Industries, Inc. - Lancaster PA
International Classification:
B41M 112
US Classification:
101129
Abstract:
The invention is directed to a technique for registering the screens of a flatbed printer so that a series of screens will be able to print different colors of ink in registration in a sequential printing operation. A device with lights in a set pattern will be used to register a series of screens. The lighted pattern on the registration device will be used in conjunction with registration openings or other markings in the screens to provide proper screen registration so that accurate printing registration will exist from the very beginning of printing of a design on a carpet or light fabric structure.
