The most essential difference between CTcP and CTP is that the exposure materials used are different. CTcP images digital information on a common PS plate, while CTP images digital information on a dedicated CTP plate coated with a special photosensitive layer.
As everyone knows, "things are rare." Since the wavelength of the CTP laser source is very demanding and the range of the photosensitive wavelength is very narrow, the imaging exposure of the CTP is extremely demanding on the photosensitive layer of the plate. The corresponding coating process and production cost of the CTP plate material are also cumbersome and expensive for the conventional PS plate which has been popularized earlier. The biggest headache for printing company purchasers is that CTP plates are not only expensive but rare, but only a few of the imported plate suppliers such as Agfa, Kodak Poly, and Fuji Star. Domestic brands are not only rare, but the specifications and performance of the plates are also far from the imported ones, which cannot meet the requirements of normal printing.
Printer operators familiar with production know that every piece of printing in production is half or more expensive than the original. If a PS version of 35 yuan, a CTP version of 70 yuan, a small-scale printing company with an annual edition of 20,000 square meters will lose 700,000 yuan a year. Although CTP can bring a lot of potential economic benefits to enterprises, in the face of such a clear cost gap, many advantages are also pale.
