Overview of High Precision Screen Computer Direct Plate Making System
The high-precision screen computer direct plate making system has been greatly developed in recent years. It has taken several years for high-precision screen computer direct plate making system to develop from paper talk to practice to production line in China.
The most important device of the CTS system is the screen imaging output device, so the system name is generally determined according to the name of the output device. 1） The composition of the CTS system is basically similar to that of the DTP system, but the output devices are very different. Generally, the CTS system consists of the following parts:
Image and text input part: This part digitizes the original and inputs various digitized documents.
Image and text processing and typesetting: CTS and DTP also use traditional image processing software, graphics processing software and typesetting software, such as Photoshop, Freehand, Coreldraw, Illustrator and Pagemaker to process images, color separation and typesetting.
RIP: Like offset printing, the RIP of CTS is to interpret various graphic and text files and PostScript files, so that the screen output device can understand and control the work of the screen output device. CTS can also accept various design software files and EPS and PS files, and can convert these file information into dots of color separation version.
Output equipment: screen output equipment is the key and difficult point of CTS. One of the main reasons for the lack of CTS in China is that the price of screen output equipment is too high and there is no corresponding production technology in China. The working principle of the output device is basically a laser exposure device. The laser spot is used to expose and harden the coated screen plate, and then develop, so that the part without light can penetrate the mesh. The output resolution of this output device is high.
