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. Reusable 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. Unlike 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. The 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.
