Application of Purple Laser CTP Technology in Newspaper Industry

Since the CTP technology is based on a fully digital workflow, the prepress system requires a higher level computer digital network platform. Therefore, its processing power and compatibility are very strong.

It has a reliable PDF workflow, full support for Postscript files, perfect RIP, and PDF workflows running on the web. Supports multiple file formats, and can output curve PDF, RIP PDF, RIP Postscript, and 1-bit TIFF files It also supports CIP3/CIP4. Therefore, good safety, rapid plate making, high production efficiency, good printing quality and low production cost can be achieved. These advantages are exactly what commercial advertising users and newspaper industry users need. In fact, these two types of users are also two core users of the violet laser. Many suppliers also believe that the violet laser CTP will be the only choice for the newspaper industry.

As we all know, the 405nm violet laser has a short wavelength and belongs to a cold light source. The stability of the light source is better. The laser power for photopolymerization violet laser exposure imaging is only 30mW to 60mW, which is only one thousandth of the power of a thermal CTP laser. . Therefore, compared to the thermal CTP high-power lasers, only the laser one, purple laser CTP will save a very considerable laser replacement costs for the newspaper industry every year. Purple laser CTP equipment uses a mature and stable inner drum mechanical structure. The technicians who are familiar with the traditional plate-making equipment photo-composing machine all know that the stability and reliability of the inner-drum mechanical structure have been verified in the production and application practice of the imagesetter for more than ten years. The internal drum type mechanical structure avoids the occurrence of the unevenness of the flat screen caused by the card version, flying plate, and spiral imaging, which are often caused by the outer drum thermal CTP, and at the same time further ensures the accuracy of the plate making imaging. The violet laser CTP brings a stable development environment and the lowest developer cost to the press. The unique grain structure and coating process of the violet laser photopolymer plate greatly extend the life cycle of the developer. In all the CTP plate processing chemicals, the tolerance of the solution of the violet laser photopolymer plate is undoubtedly the largest. At the same time, the process stability is greatly improved, and the operator's labor intensity is greatly reduced.
