THE ADVANTAGES OF CTP

As technology advances and market maturity, thermal and thermal CTP plate by virtue of its strong advantages, will lead the farewell plate darkroom, digital guide to green printing the printing industry, and the user will eventually put CTP as its on the entire printing process must be an integral part.
CTP output machines are within the mainstream of drum machine, drum machine outside the points, so the platform type is non-mainstream; to plate imaging light, mainstream red felt, a sense of green, blue-violet light and other visible sense, and 830nm, 1064nm infrared, which are not visible, while others are non-mainstream way.

1. thermal non-mainstreamIn the thermal output has more non-mainstream, including A) the only red warm-up version; B) phase-change-free wash; C) levels without thermal plates in three ways.Mainstream approach is direct thermal mode red version, but free version is a direct red warm-up pick up the banner of the thermal method. Thermal non-mainstream output (A) the only red version of the warm-up mode. Thermal method to be warm, it is a thermal CTP plate mainstream, but must be sensitive, the version before the heat into the red, so have a role to the thermal part of the photosensitive layer from the surface to the bottom level of catalytic formation of a chain reaction, top-down complete with fully stamped the role of the Ministry of bridge resin. This approach seems a bit outdated, from mainstream to the mainstream format, but its greatest advantage is the exposure of negative film type, a light-sensitive part of the only natural way to form a stamped, so the long version is still used in commercial and newspaper web offset printing flat printer, it can only stamped to form the Ministry of exposure, while the version and edition of the mouth is not the end of the exposure areas, the smaller, faster, the other negative film type thermal version and re-exposure bake can be produced by printing grain hardening, stingy amount of anti-Indian, in the extremely long printing twenty plates, such as baking can increase the anti-Indian four hundred thousand copies, a large number of publishing and the newspaper have a positive effect. Although it is troublesome, but also affect the conditions of heat transfer and dot reproduction version, but the newspaper asked 1200dpi, slightly swollen network effect is not large, so the thermal heating and then after washing the old way, though not the mainstream version of thermal , but because of sensitive and resistant to negative film printed reasons in this regard will be continued with a very long time. Thermal non-mainstream output (B) phase-change thermal red-free version. Phase-change thermal red-free version, published by Asahi Kasei of Japan, mainly by coating the thermal layer in the layout, it usually is hydrophilic, but the thermal exposure, the coating layer is stamped on the Department of the lipophilic, and Oil falls on the pro-stamped the ink department, red-free thermal printing plate is unique in the way of the future commercialization of whether the market remains to be seen, but if they can use is DI water machine plate machine the best version of the material, because and without shedding of debris generated. Thermal non-mainstream output (C) the level of thermal plates free. Thermal non-standard plates, most of the use of the infrared laser heat energy, so that no horizontal plate of the layer off, you can become adhesions ink stamped, the present United States and Japan Toray two main Presstek However, Presstek DI is still with the plate as much, Although technology is quite mature, but still no plate costs down, we can not have a great expansion, the formation of a special field of non-mainstream CTP plates.
