Abstract
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, reducing cost and improving quality.
Claims15
A method of making a laminate, comprising the steps of:
- (a) obtaining an first image sheet having a first surface and a second surface;
- the first surface being compatible with inks;
- (b) obtaining a backing sheet having a third surface and a fourth surface;
- the third surface being liquid photopolymer compatible;
- the fourth surface being at least partially coated with an adhesive coating which adheres more strongly to the fourth surface than the second surface;
- (c) applying the second surface of the image sheet to the adhesive coating;
- and
- (d) printing a first image on the first surface.

A method of making a laminate, comprising the steps of:
- (a) obtaining an image sheet having a first surface and a second surface;
- the first surface being comprised of a microporous coating;
- (b) obtaining a backing sheet having a third surface and a fourth surface;
- the third surface being liquid photopolymer compatible;
- the fourth surface having an adhesive coating which adheres more strongly to the fourth surface than to the second surface;
- (c) applying the second surface to the adhesive coating;
- and
- (d) printing a first image on the first surface.
5 more elements
A method of making a laminate, comprising the steps of:
- (a) obtaining a first release liner having on one side a first polymer-based surface, and a first ink-receptive surface on the other side, which is either:
- (1) polymer-based;
- or
- (2) a microporous coating;
- (b) obtaining a backing sheet with a photopolymer-compatible surface on one side of the backing sheet and a first adhesive coating on at least a portion of the other side of the backing sheet;
- (c) placing the one side of the first release liner against the first adhesive coating;
- and
- (d) printing a first image on the first ink-receptive surface.
