Reusable Plate System Using Anodize Aluminum Substrate

摘要

Reusable plates system has capability of recycling offset printing plate. A process of repeated erasing and reimaging provides not only economic advantages but also environmental benefit as well.rnReusable plate using anodized aluminum are imaged in the same fashion as today's thermal-plate CTP systems and therefore provide the same level of printing quality. Plate life is good for 100,000 impressions per image and each plate can be erased and re-imaged up to 20 times.rnUnlike direct imaging system equipped on a press at each printing unit, the reusable plate system is a stand alone, off-press system. As a single unit, investment costs are lower, and it allows for plate production to be accomplished in a more-favorable environment. Moreover, as an off-line system, the press does not need to be stopped during plate making, improving overall pressroom productivity.rnThe RPS-X1 as a prototype of reusable plate system uses sleeve type of plate carrier to match the variable cutoff sizes of web offset press that readily accommodates a range a different sleeve circumferences.
