Digital Color Printing with an Electrophotographic Web Press.

Digital Color Presses make it possible to print short runs in full color with offset-like print quality at an acceptable cost per page. The Xeikon DCP-1 is the first web-fed digital color press available on the market. It uses 8 electrophotographic print stations, 4 on each side of the paper web, enabling one pass duplex printing. Each printing station is equipped with a high quality LED-array which supports an addressability of 600 dots per inch with more than 200 distinct density levels per pixel. The press uses a dry toner, dual component xerographic process, and operates at a speed of 35 duplex A4 sheets per minute. The press is driven by an advanced digital controller which optimizes the time from document creation to printing and which offers unique features such as variable data printing, poster printing, and electronic collation. This paper discusses the technology on which the press' performance is based. The focus is on the special functions offered by the digital controller.
