Neil: You keep talking about the bulk of the CTP Plate market being short run, and thus Presstek. (est. 40 plates a day etc. The following article refers to a printer that uses 3000 CTP - NON PRST plates per month. As I have stated before PRst is fighting to be a big fish in a SMALL NICHE MARKET. SEE: napco.com Title: Computer-to-Plate Part I: Overview of Direct-to-Plate Technology for Books" See the article, but the following summarizes CTP Plate technology: Note the reference to ALL plate manufacturers developing thermal technology, and the DIFFERENT MARKETS, FOR DIFFERENT PLATES. Greer explained that CTP systems can image on a variety of plate materials: silver diffusion, photopolymer and a hybrid photopolymer with silver halide on top and thermal. Thermal plates and platesetters have been available for about the last year and a half. Silver plates are long lasting. You can get between a half million to a million impressions from a single plate. With photopolymer plates there is no silver to discard. If the plates are baked after developing, you can use them for a million or more impressions. With hybrid plates, the top layer is silver halide; the bottom layer is a conventional emulsion layer. You can get up to a million impressions from a hybrid plate. He is aware of only one company (Polychrome) making hybrid plates. Thermal CTP is a new technology and Gerber has just released a thermal platesetter. Greer said his company and other CTP manufacturers are big believers in thermal CTP. "We believe thermal is an emerging technology and one we'll all be using the next few years. All plate manufacturers are developing thermal technology because of the potential benefits." The thermal CTP plate is sensitive to heat, not light, so it's daylight-safe and gives very long run lengths (millions). It offers the sharpest dot of any plate type and it offers the potential of a dry processing procedure. For example, after exposing, all the operator would need to do is wipe the plate with wet rag to develop it, then put it on press. Search said CTP has already paid off for Berryville Graphics, a $7 million book printer in the Shenandoah Valley of Virginia. The company has used CTP since April 1995. Within six weeks of installing the system they were producing up to 3,000 CTP plates per month.
