CTP's "Dark Horse" CTcP debuts As early as 1995, Germany's BasyPrint (BasysPrint) has launched the first system using CTcP technology, but it is only an experimental product; Drupa2000, using the traditional PS version of the ultraviolet platform direct plate-making machine officially launched, causing Great response, but did not rank among the mainstream technologies of CTP direct plate-making technology; Drupa2004, in the promotion of the hottest JDF digital workflow of the year, the CTcP technology based on traditional PS plates, which debuted almost at the same time as the thermal CTP, was buried nearly 10 It was only a year later that it shined, just like "Cinderella" found her "crystal shoes" and suddenly became a "princess", which aroused widespread concern in the printing industry. Other companies have also launched their own CTcP products. CTcP is so popular because of its unique advantages. Adopt square dot imaging, achieve high-quality printing at a lower resolution, and can significantly shorten the RIP time, reduce the amount of data processed, save the memory of the computer system, and expose faster. The dot matrix type corresponds to the PS version of digital imaging, which can eliminate the phenomenon of dot expansion and dirty spots during plate making. Give full play to the potential performance of the traditional PS version. It can reproduce 1% to 100% of the dots excellently, and the printing controllable range has also been expanded to 1% to 99%. The choice of printing plate is due to "live". For different jobs, both negative and positive plates can be used. Prints with general textual content as the main content, use the negative PS type (N type); if the image area on the plate is large (such as commercial prints), or some special inks are highly corrosive (such as UV inks) , Can use positive figure PS version (P type, strong chemical resistance, high printing resistance). The fast, stable and smooth integration with the traditional PS printing process not only ensures the stability of printing, but also ensures the economy and high efficiency. The PS machine printing and image reproduction capabilities have been recognized by the market for a long time, and the technology has been perfected, and has been widely used in the printing industry. The introduction of CTcP can continue to use the original processing machine and developing solution; it can be networked with the existing network environment to achieve low-cost operation. The development trend of CTP direct plate-making technology CTP direct plate-making technology has entered the era of "Three Kingdoms" of thermal, violet laser CTP and CTcP. Thermal CTP leads CTP with high technical content, high platemaking quality and technological innovation. Violet laser CTP inner drum type is used to simplify production, high-speed exposure, miniaturization of imaging unit, and mature technology to become CTP rookie; CTcP uses traditional PS version, low comprehensive cost, and connects with the original pre-press equipment of the printing house And a sudden rise. Customers need to be the driving force behind a single CTP device to a fully digital workflow. A systematic and comprehensive solution that enables printing and proofing at any stage of production, permits last minute modification and other high requirements, helps eliminate the influence of human factors, facilitates the digital transmission of information, and facilitates the rapid discovery and resolution of problems To ensure the efficiency and safety of the entire system. Prepress equipment resources are shared. One RIP, multiple output, the production efficiency and technical level can be improved, and the compatibility and mixed operation of file formats between multiple systems can be easily achieved. CTP equipment with replaceable light source technology. Under the diversified situation of CTP light sources and plate materials, replaceable light source technology will ensure that customers investing in CTP equipment will not be affected by changes in light sources. Meet the increasingly stringent print production requirements. It will further meet the requirements of high-speed output, diversified specifications, and processing automation. At the same time, the printing durability will be greatly improved, and it can meet the printing requirements of high-definition color printing dots and other aspects. The CTP workflow will be further specialized for different market segments. For the printing of books and periodicals, the emphasis will be on the strong book layout, accurate and safe handling of double-byte Chinese functions, high-quality printing effects, high durability of the printing plate, and UV printing, etc .; for newspaper printing, it will adapt to the timeliness of publishing Performance requirements, highlight the ultra-high production efficiency of the plate-making machine and the ultra-stability of the system operation, accurately and safely handle the double-byte Chinese function, and the smooth data exchange function with the front-end editing system; for packaging and printing, we will focus on promising high stability And easy to save, strong UV printing adaptability, meet the requirements of ultra-large format packaging, etc .; for commercial printing and printing plate output center will meet its large format, high quality and high efficiency requirements, to ensure the openness of the data processing process , Compatibility and high speed to meet the requirements of quickly obtaining high-quality printing effects. The matching of CTP and digital proofing is becoming more and more important. Such as remote proofing, screen soft proofing, digital proofing, etc., so that customers can preview the digital printing effect in time. Three-point technology characteristics and application analysis The application of thermal and violet laser CTP needs to change all conditions from development to printing, requires enterprises to spend more costs and energy to carry out technical innovation and comprehensive innovation of production processes, requires a lot of training for employees, and requires a longer Adaptation period. At the same time, whether the future CTP is thermal or purple laser is far from being finalized, and different systems cannot be compatible or upgraded; we cannot predict the future direction of development. If more mature and stereotyped technology appears, it will cause the existing thermal or violet laser CTP system to be paralyzed and unable to operate, making it a pile of waste. For general printing companies, the gap between the input of the thermal or purple laser CTP from the plate-making equipment to the comprehensive update of the plate material and the benefits it brings is really too large. It is true that the resolution of thermal plate-making can be as high as 400 lines / inch, but in order to match this line number, the requirements on the special plate materials and the matching paper, ink, blanket, printing equipment, etc. are also higher. There are not so many jobs with such high requirements on the number of threads in the market, especially in the face of the increasingly low-profit printing market, the noble and "expensive" thermal CTP technology is like "Golden Saddle" for general printing companies. "BMW driving wheel" may just be a luxury that cannot be "consumed". Although CTcP technology still has some shortcomings at present, such as the general PS version, the sensitivity is generally low, and the speed of plate making is not satisfactory; DMD micro lenses reach 1.3 million, which is very precise, which will bring certain difficulties to daily maintenance and repair, and failure replacement . However, compared with the thermal and violet laser CTP, CTcP is a "one-time" investment that does not cost much, and only changes and replaces one of the processes. It can make the traditional PS printing process and digital technology seamlessly link, gain new life and Promote. Even if the traditional PS printing process is replaced by a better process in the future, it will always have a much smaller "sacrifice" than a full update on the left and a full update on the right. Based on this, it can be considered that thermal, purple laser CTP and CTcP have their own advantages and disadvantages. Based on the actual needs of the company's market positioning and technological transformation capabilities, we comprehensively consider from the aspects of time, quality, and cost, and can reasonably delineate The option that suits you best. As far as the "consumption level" of the CTP family is concerned, if the thermal sensitivity is an elegant and elegant "nobility", the purple laser is a fashionable and sentimental "petty bourgeoisie", and the CTcP is better at achieving advanced and adaptable. "Civilians" who share the most advanced technological achievements with the perfect combination of efficiency, economy and existing pre-press and printing equipment. Except for a few high-end printing companies, CTcP technology may be more suitable for the market positioning and actual needs of most printing companies. It should be these companies, especially book printing companies, which are currently among the more ideal options for CTP.
