Process to produce a custom-color overlay

摘要

Methods for making an imaged custom-color overlay. The method includes a) providing a photosensitive ink of a selected color; b) providing a carrier sheet comprising a transparent support sheet and an ink-receiving layer; c) custom-coating the ink-receiving layer with a layer of the ink; d) drying the ink; e) imagewise exposing; and f) developing. The invention permits an end user of a proofing system to make an imaged overlay in a multitude of custom colors on an as-needed basis, without being limited to those colors that are provided by a manufacturer. The methods are suitable to make custom-color overlays using both analog and digital processes. The photosensitive ink may be water-based. Methods for making an overlay proof including an imaged custom-color overlay are also disclosed. The end user of a proofing system may therefore make highly accurate overlay proofs suitable as contract proofs.
