DEFINITION

Classification: 101/463.1

Lithos:graphic plate making, and processes of making or using copy elements, and elements, per se:

(under subclass 130) Process including (a) the manufacture of a printing plate having an ink-repellent portion and an ink-receptive portion thereon, or (b) the process of manufacture or use of a master sheet having an ink-design thereon, said design being capable of transfer to a plurality of sheets or surfaces to be printed without re-inking between successive transfers, or (c) such master sheet material, per se.
