Lithographic printing system with reusable support surfaces and lithographic constructions for use therewith

摘要

Lithographic printing constructions are removable from a permanent support, which may be a metal sheet affixable (usually by clamps) to a plate cylinder, or may instead be the permanent surface of such a cylinder. In this way, the traditional "plate" is replaced with a thin, easily manufactured printing member, which is separated from the support following its use.
