ABSTRACT:
A positive working radiation sensitive plate is image-wise exposed, developed and desensitized, and dried. Thereafter an oleophilic composition including a solvent capable of softening the image is applied to the plate and the plate is then washed to remove the oleophilic composition from the non-image areas. The image accepts ink readily even when the image-wise exposure is effected using a continuous tone original in the absence of a half-tone screen.
