(under subclass 1) Process directed to forming a surface capable of conveying intelligence or a design by reproducing in printed form.
(1) Note. Included herein is the combination of forming the mat or matrix and casting of metal thereagainst to form a plate.
(2) Note. The step of applying a backup member to a preformed printing plate is not considered forming a printing plate to be incorporated herein. This operation is found in the composite article forming area, i.e., subclasses 91+.
