Abstract
Monochrome and polychrome color proofs, for the graphic arts industry, having an image carrier containing two layers A and B to control optical dot growth are described. Layer A contains at least one polyolefin and, in a preferred embodiment, a light-reflecting white pigment. Layer B contains at least one binder, at least one light-reflecting white pigment at between 50% and 90% by weight relative to Layer B, and at least one light-absorbing pigment. A process and a means for preparing such monochrome and polychrome color proofs are described.
Claims5
An image carrier for making a color proof comprising, in order:
- (a) a substrate having an image-side surface;
- (b) a Layer A containing a polyolefin present on the image-side surface of the substrate;
- and
- (c) a Layer B containing at least one light absorbing pigment, at least one light reflecting white pigment, and at least one binder.
