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.
