Abstract

493,135. Printing-surfaces. ADDRESSOGRAPH-MULTIGRAPH CORPORATION. March 1, 1937, No. 6071. Convention date, April 3, 1936. Drawings to Specification. [Class 100 (ii)] A planographic printing-plate comprises a printing-surface of a water-absorptive cellulosic material resistant to disintegration by water, receptive of grease when dry and resistant to grease when damped, the printing-surface being united to a co-extensive flexible support impregnated with a waterproof adhesive. Such a plate may be prepared for printing by directly impressing a greasy image thereon, e.g. by means of a typewriter, heating the plate to integrate the image and then dampening the face to render the non-printing areas inkrepellent. The plate may be secured directly to the printing cylinder of a press, or may be attached to a thin metal sheet adapted to be secured to the printing member. The plate may comprise a printing face of paper saturated with a cellulose derivative, or of a film of cellulose derivative, secured to a support of heavier paper impregnated with a waterproof thermo plastic adhesive. Specification 430,111 is referred to.
