Digital Proofing--Halftone-hungry Prepress Proofers

It is imaged by a technique called Laser Induced Film Transfer (LIFT). The proofs are non-photographic, require no chemical processing and are insensitive to normal daylight. The proofing materials consist of a coated receptor, four-color donor sheets (CMYK exposed individually) and a base paper sheet that receives the positive, color images from the receptor to complete a proof that looks like a printed sheet.
