  • Detail

CTP is only a transitional technology, and digital printing has finally achieved positive results.

the share of traditional PS plate and CTP plate has been significantly adjusted. The share of CTP in Europe and North America has been rising, and now it has% share. There is no doubt about the development direction of CTP. From the perspective of European market demand, customers focus on CTP, whether there is CTP version, what CTP version is there, and whether the quality is stable. For PS, the PCU between titanium alloy end plates is a patented formula version, which is no longer concerned. At present, 150million of the 450million offset printing plates in the world market are CTP plates, mainly concentrated in the European and American markets. Even in Asia and Africa, this trend is very obvious. On the other hand, developing countries including China have both traditional PS plates and CTP plates, such as Plate Companies in China, India, Brazil and other countries. These situations show that traditional plates still have certain vitality in some areas, but the future development direction will be digital CTP plates

the current equipment manufacturers are divided into three situations: the first is the thermal camp. Creo and Luscher strive to promote thermal technology. Their products are all positioned on the 830nm thermal plate making machine. The equipment specifications extend from folio to 4-open and super large specifications. The plate making speed is faster and the degree of automation is higher. The second kind can be divided into two kinds: one is the photosensitive camp connected with civil engineering. Esko, Krause, etc. are represented by pushing photosensitive plate making machines. The equipment is more exquisite, the price is more reasonable, and the power is more powerful. The third camp, represented by Agfa, Heidelberg, screen and ECRM, produces both thermal and photosensitive plate making machines to fully meet the market demand. Its commonness lies in the improvement and improvement of plate making machine, which promotes the development and positioning of CTP plates: thermal and photosensitive plates will promote the popularization of CTP

CTP plates of plate suppliers are almost all thermal and photopolymer violet laser plates, and the plate base is mainly aluminum plate base. There are the most kinds of thermal plates, which is consistent with the high printing resistance, resolution and wide range of adaptability of thermal plates. KPG, which is a leader in thermal technology, has exhibited a variety of thermal plates, from the preheating negative figure themal830 to the treatment free thermal direct non process printing plate, which meets various market needs, without preheating positive plate electric excel, and can quickly produce finished parts as the main products; Agfa has the most types of plates. While maintaining the silver salt plate market, the focus has begun to shift to thermal technology; Fuji's focus is on photosensitive plates. Almost all plates equipped with purple laser equipment on display have Fuji's brillia LP NV purple laser version

due to the advantages of fast photosensitivity, high resolution, low cost of laser, simple operation, adjustment and control of plate making machine, the performance of purple laser CTP plate is closer to that of traditional PS plate, especially the power of laser diode is increased from 5MW to 30MW, 40mW and 60MW, and the service life is increased to 6000 hours, which further promotes the progress of purple laser technology. For example, Fuji, Agfa, erjiao and other companies have exhibited the purple laser photopolymerization version, which can predict that the purple laser technology will develop at a faster speed in the future, especially in the medium format, it will give full play to its advantages in all aspects

in addition, CTP technology with large format and high automation for commercial printing, whether CTP plate making machines such as screen, Creo, Esko, Krause, or plates of KPG, Agfa, Fuji and other companies, has CTP equipment with large format. Therefore, it is certain that CTP technology has entered a mature stage. Thermal technology and UV laser technology are the protagonists of CTP plates. At the same time, the 10 things of UV exposed CT are changing the polymer new material industry! CP, CTUP and polyester based thermal and photosensitive plates also enrich and expand the CTP family

looking at the Chinese market comprehensively, the most advanced and the lowest level of printing demand coexist. In the long run, CTP is definitely a development trend, and even CTP may be just a transitional stage, and ultimately digital printing. It calls on Chinese printing plate companies to strive to improve quality, enrich product varieties to meet different needs, and speed up the improvement of technical level. They should not continue to take the road of vicious competition, completely change the image of low-quality and low-cost Chinese plates in the international market, and meet the new digital era
