<p>A negative working method is disclosed for the formation of an overlay colour proof in pre-press graphic arts. A pigmented photosensitive element provided with an adhesive layer is subjected image-wise to exposure by actinic radiation thereby undergoing photopolymerisation in the exposed areas. The exposed areas are transferred to a receiver base and form there a negative image. By repeating this procedure with different colorants, a full colour proof can be obtained.</p> |
