CTP = computer to plate.
CTP technology is plate-making technique that transfers digital or pages edited in an electronic prepress processing system (CEPS) or color desktop system (DTP) directly to a printing plate. Its characteristics are: In the material aspect, the photographic film and its rinsing chemicals are omitted; in the process, the film exposure rinsing, revision, printing and the like are omitted; in the device, the darkroom and film exposure are omitted. Flushing equipment; in terms of efficiency, reducing costs, saving time and space; in terms of quality, image transfer quality is significantly improved, reducing environmental pollution. CTP (Computer-to-plate) technology appeared in the 1980s. This period is the initial stage of direct plate-making technology research.
CTP (Computer-to-plate) technology appeared in the 1980s. This period is the initial stage of direct plate-making technology research. Therefore, during this period, both technical aspects and plate quality are not very mature. In the 1990s, equipment manufacturers worked closely with printers to accelerate the pace of research and development of this technology, and reached a level of maturity and industrial application during this period. Thus, at the Drupa Printing Exhibition in 1995, 42 CTP systems were exhibited. At Drupa2000, more than 90 direct-to-plate system and material manufacturers from around the world exhibited nearly a hundred products.
