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.
Colour proof consisting of polyester sheets laid on top of each other with their image in register, as compared to integral proof. Each sheet represents the image to be printed in one colour. Also called celluloid proof and layered proof.
Off-press color proof produced with four dyed or pigmented overlay films.
A process of proof making whereby the color separations are individually exposed to light sensitive film. This film is then set in registration with a piece of white paper in the background.
A color proof, such as a Color Key, consisting of polyester sheets laid on top of each other with their image in register, as compared to an integral or composite proof. Each sheet represents the image to be printed in one color. Also referred to as a celluloid proof or layered proof.
A proof created from color separation negatives that uses sheets of acetate overlaid on each other to create the color image. Each film layer represents one color.
Color proof consisting of polyester sheets laid on top of each other with image in register. Each sheet represents the image to be printed in one color. Also called celluloid proof and layered proof. Overprin - To print additional image over a previously printed image, such as printing type over a screen tint. Also called surprint.
