The Xerox CiPress High Speed Waterless Ink Jet System uses many Solid Ink inkjet technologies from existing office products. One significant difference between the office Solid Ink products and CiPress is the printing architecture. The office ColorQube family of products first builds an image on a drum in multiple passes and transfers that image to paper when complete. The CiPress production system prints directly to paper and the ink is subsequently spread mechanically using high pressure. This process requires careful control of the paper temperature to achieve the best image quality.
