Definitions for "Overlay Proof"
A type of PROOF, made from film, where each color is created on a clear sheet of acetate, and then all four colors are taped to a sheet of paper in such a way that the sheets can be flipped up individually. This type of proof allows examination of each individual layer of color separately, and allows easy checking of TRAPS. Contrast LAMINATE PROOF, DIGITAL PROOF. A Color Key is one example of an overlay proof.
