Definition: A prepress proof is an analog or digital proof that uses inkjet, toner, dyes, overlays, photographic, film, or other techniques to give a close approximation of what the finished piece will look like. Unlike a press proof, the prepress proof does not use the actual printing inks therefore color proofs may not be quite as accurate as a press proof. Analog prepress proofs include inexpensive contact proofs, such as bluelines, used for checking positioning or where exact color is less critical; and, more expensive but increasingly accurate color overlay and laminate proofs. While analog prepress proofs use photographic or film techniques, digital prepress proofs print directly from the digital files to inkjet, laser, and similar printers.
Also Known As: Dry Proof | Off-Press Proof
Examples: Digital halftone, bluelines, Color Key, Matchprint, and Cromalin are all common types brand name and generic prepress proofs.
