In recent years, inkjet printers have made great progress, mainly reflected in higher print speed and print resolution, longer print head life, and higher screen quality, such as Epson 4800, 7800, 9800 and other printers. Century Rainbow K3 pigment ink with a resolution of 2880 × 1440DPI and a minimum ink drop of 3.5 picoliters. The fine ink drop and intelligent ink drop conversion technology ensure high-quality output. Reached the precision of 175 lines / 2540DPI of laser imagesetter, so it can be used for color printing and plate making. In addition, the price of inkjet printing system equipment and consumables is low, and the process is simple, so the cost of plate making is low. This has led to the rapid development of inkjet direct platemaking, which can be widely used in the printing of books and newspapers. 1. Plate-making process and advantages of inkjet CTP plate: The plate-making process of inkjet CTP can be generally divided into two types: PS plate type inkjet CTP plate and bare plate type inkjet CTP plate. 1. PS version inkjet CTP version PS version inkjet CTP version is to apply a transparent ink absorption layer on the ordinary PS version, and then use the inkjet printer to print graphics on the ink absorption layer. After printing, developing and washing, the printing plate can be printed on-hook. Compared with the traditional PS version process, it eliminates the need for film, imposition process and corresponding equipment. At the same time, the plate-making time is shortened, and the plate-making cost is greatly reduced. PS plate type CTP plate material has been successfully developed by Pratt and Beijing Printing Institute in China, and began to be produced and sold. 2. Bare inkjet CTP version Bare inkjet CTP offset printing plates do not require printing and imaging. There are two types. The first is to coat a layer of ink absorbing layer on the aluminum mesh base of sand mesh first, and then inkjet imaging on the absorbing layer. The absorbing layer must have strong ink absorption and high adhesion to the aluminum base degree. The second is inkjet imaging directly on the aluminum mesh substrate.
