Current CTP (computer To plate System) wave has been launched in the global printing industry, digital printing time has come. In this unprecedented revolution in printing technology, Who Controls? "China and India Jin Zhou," loudly chanting: "its own independent technology research and development intellectual property rights of CTP, to the full realization of the Chinese printing industry 'pre-press
Electronic Digital, high-speed color printing, printed various automation 'of the' three of 'ambitious goals. "
"Laser typesetting technology" in the 80s of last century by the academician Wang Xuan, inventor, became the printing technology industry in China following the Bi Faming movable type since the second revolution. Into the 21st century, who can set off the third Chinese printing industry revolution?
ZHOU Jin Technology Co., Ltd. Beijing China and India on this issue, general manager Dan Junmin made a solemn reply: "China and India ZHOU Jin rely on independent R & D technology to produce the first domestic 'digital-to-plate machine' (CTP), a successful to set off the third Chinese printing technology revolution, the Chinese printing technology into the current international advanced CTP era. "
In the recently-concluded 2008 China International Printing Technology and Equipment Exhibition, ZHOU Jin Technology Co., Ltd. Beijing China and India rise to great concern to the participants. Gengrang The general manager Dan Junmin excited, they developed a smooth digital platesetter special assessment by the National Science and Technology, and was included in the 2009 National Key New Product Plan, issued by Ministry of Science and received 300 000 dollars a special bonus.
Successful only once failed 99 When talking about technical difficulties, Shijun Min said: "In fact, every subject and links are difficult issues. From the electronics side, in order to
CTP Systems Lasers, for example, the system needs 830 nm laser, the laser beam for the 32 or 64, which requires a separate control for each road, and the whole 32 or 64 of the laser uniformity to be consistent. More specific to each road, the control pulse, must remain in the microsecond level is consistent with indicators. "
Shi Junmin further explained: "popular talking point is we need to microsecond laser well within the control of the current increased from 0.2 amps to 1.2 amps, the work is completed back to 0.2 amps again, and to ensure Lasers can not be burned, and up to 1.2 amps when the current time, can continue for some time, the whole working process, need to be completed within 30-50 microseconds of time. the work process, including the current rise and fall, but also in current rise in the process of "rising" must be shaking, not slash up, this is a difficult point in the country is very much advanced technology. to meet the required targets for improvement is the laser's control, good number of components of protection, if good control of current, more than 1.2 amps or 1.5 amps, a five or six thousand dollars, laser, only "pop" look, this component will burn out. this time in the early R & D There have been such a failure, in his own words, failure is 99 times, the last one before it. "
Shijun Min said had 16 lasers in the debugging time, met great difficulties, because the laser effect in the aluminum on the role must be consistent, but also because of the problems involved are more grip It's the law, a single optical system, the focal length of the target line, and laser point would not work. Adjust the angle so well, and focal length are not in compliance, and had a winter full transfer no solution. And from the optical point of view, to 32 laser, for example, laser hitting aluminum on each point, theory is 15 microns in diameter, for a smooth and various protective measures, the current level of technology is simply unattainable only the optical system through a transformation to a high-resolution. This also requires numerous experiments, in order to obtain accurate parameters. Laser hitting aluminum on precision how much needs to accurately calculate the optical system of the "magnification, resolution, transmission," the exact parameters of these areas to meet after repeated experiments, testing to meet the requirement. "There is also a difficult mechanical control techniques, CTP system has a similar drum parts, called the imaging drum. I am an expert from China Computer Parts, usually analyzes all kind of industries situation, such as private car number plates , car top cargo carrier.
