CTP purple laser technology is expected to lead the printing market trend

at present, the CTP field is still the coexistence of thermal and purple laser technology. However, the development of violet laser CTP is more remarkable. More and more enterprises begin to invest in the research of this technology because they believe that the future printing equipment market will be dominated by violet laser CTP technology

advantages of purple laser CTP technology

since the purple laser light source was officially introduced to the market in May 2000, the most advanced thermal light source in CTP equipment has been severely challenged. 3. The advantages of this new light source have attracted many users

faster

purple light source has higher imaging speed than other common CTP light sources such as green light and red light. With this feature, there is no special department and specifier for equipment production to increase the scanning speed to 55000 lines/min, while the scanning speeds of infrared laser and green laser are 20000 lines/min and 37500 lines/min respectively

higher accuracy

using the previous light source can only show 200 DPI points on the photosensitive plate, while using the purple laser can improve the accuracy to 250 DPI

longer service life

the maintenance period provided by the laser manufacturer for the purple laser is the same as the previous green laser, which is 3000 hours. However, the operating characteristic of violet laser is that the laser only needs to be started when it is actually imaged, and the rest of the time will not lose the life of the laser. Other laser operating modes are to start the laser at the same time after the machine is turned on. Therefore, the actual life of violet laser is longer than that of other CTP laser sources

set off a research and development upsurge

the purple laser CTP technology was first introduced by Fujifilm company in drupa

2000 exhibition. In the past four years, Agfa, Toshiba, Sony, Panasonic and other enterprises have invested in the development and production of violet laser CTP system and consumables. This technology is gradually maturing. At the same time, these enterprises have increased their investment in the Chinese market, which is the only place for major printing equipment manufacturers in the world

In November, 2004, Fujifilm Co., Ltd., a joint venture between Fujifilm Co., Ltd. and China Institute of Printing Science and technology, held press conferences in Shenzhen, Shanghai and Beijing. Koji Yokota, general manager of Fuji starlight, said that although Fuji starlight can provide thermal and purple laser CTP plates at present, purple laser will be the leading technology in the future

its latest Fujifilm starlight brilliant

lp-nva violet laser photopolymerization CTP version has attracted much attention. This plate is a Chinese version based on the purple laser photopolymerization CTP lp-nv developed by Fujifilm and improved many times after extensive domestic market research. It has many advantages: by introducing the unique 3-layer coating and multi-layer sand mesh technology of Fujifilm, the high sensitivity and high precision of the plate can meet the needs of the newspaper industry and color commercial printing; The yellow safety light can be used in conjunction with the operating environment of purple laser CTP equipment, making the operation more convenient; With ordinary ink, the printing power can reach 200000, and the printing power can reach 1million after baking

In September, 2004, founder electronics of Peking University may be damaged; Change the tightness of the chain of the testing machine once every half a year; Operators should be familiar with the statement. The company and Agfa signed a new year's strategic partnership agreement to jointly create the world's best purple laser CTP system solution for newspapers

60mw laser diode is becoming the first choice of violet laser CTP products. Agfa currently plans to use 60MW violet laser diodes in its Palladio and Galileo plate making machines. Galileo is a 4-page or 8-page internal drum system with semi-automatic or fully automatic configuration. At high speed, it can output 22 plates (8 pages) per hour with a resolution of 2400

dpi. Palladio is a four opening (B2) lithographic plate making machine developed by Agfa with a low threshold for entry. Its latest manual version installation model is targeted at low-end users. When the output resolution is 2400

dpi, 17 versions are output per hour

David

furman, senior marketing manager of CTP system of Agfa, pointed out that with the continuous enhancement of laser energy and the continuous improvement of violet laser emulsion, violet laser technology will become the next development goal

we believe that with the efforts of many printing equipment manufacturers, each progress of violet laser CTP technology will accelerate its popularization in China
