CTP Laser Technology
The laser light source used by CTP can be divided into visible light source, infrared light source, and ultraviolet light source according to its spectral characteristics. The thermal CTP uses an infrared light source; the photosensitive technology includes violet laser technology and CTcP technology.
The quality of plate-making network sites for thermal, violet laser, and CTcP has always been the focus of debate; the characteristics of different workflows and the application of frequency-modulated screening technology are also varied. It has been proved through long-term practice and production application that the advantages of thermal platemaking are no longer advantageous. Doubt, and the "square spot" technology of Kodak's thermal CTP platesetter is now the highest level.
