Negatives and laminates containing negatives for exposing liquid photopolymers in UV flexographic plate making are created by printing opaque images directly onto the protective or release cover films used in plate making processes. Combining negatives and cover films in this way eliminates two layers and two interfaces in the exposure process, thereby reducing cost and improving quality. By enabling the negative film images to approach the liquid photopolymers as much as possible, printing dots of digital quality are generated. |
