Abstract

A plate for supporting one or more sheets of originals to be copied and a sheet of sensitized media is supported so as to minimize sag in one direction across the plate. The plate may be inclined with the top and bottom edges of the plate entirely supported or only supported at location(s) spaced inwardly from the edge of the plate. When a cover, such as a flexible curtain, is mechanically pressed against the plate, as by a roller, air gaps between the originals and sensitized media are minimized due to this plate support system. This improves the speed at which high quality prints can be obtained.
