Digital Proofing--Halftone-hungry Prepress Proofers

PolaProof is a digital halftone proofing system that uses Laser Ablation Transfer (LAT) to transfer pigmented printing inks directly to actual printing stocks with real halftone dot structures.

PolaProof delivers oversized, four-up, one- or two-sided proofs up to 400 lpi. The unit consists of the PolaProof 2230 imager, PolaProof ink sheets, the Polaroid RIP, Pola-Proof Windows NT and the Pola-Proof finisher. The latter provides a matte, semi-gloss or gloss finish that anticipates the optical gain of the press.
