imagesetters and Platesetters Essentially the same technology as laser printers except that they print at a higher resolution on photosensitive paper or film instead of a photoconducting cylinder. Some imagesetters can directly expose plates (platesetter or computer to plate", see next section) Can produce very high resolutions with correspondingly high frequency halftones or high quality stochastic screens. systems can be Capstan or drum. Many use IR lasers, such as our AGFA ProSet 9800.
