It was put through its paces this weekend while continuously running 11,000+ sheets an hour on coated paper! The net result, given that the Perfector prints both sides of the paper in one pass, is a yield of 22,000 impressions per hour! Running at our standard line screen of 200lpi, the quality was amazing. Our motive for purchasing this press was simple-It is another solution our clients have asked for. Complete with Heidelberg's unique Pre-Press Interface, all color is controlled in a 'closed loop' system.
