CTCP： Extension and Development of Traditional CTP
CTcP is the abbreviation of Computer To Conventional Plate, which Refers to the computer-to-plate making on the traditional PS plate, which is a kind of CTP process。 Realize the form, but the pre-press process and machine printing do not need to make any changes, continue to use the traditional。 The primary imaging principle of UV plate printing and the light source are basically unchanged. The only requirement is, with UV-Setter configured in the system, most offset printing plate materials can be used UV-Setter exposure imaging。
Unique advantages
①Significantly reduce the cost of pre-press production. One is to simplify the process flow and reduce the film, manual imposition, and printing In the traditional process, other processes can save consumables and related costs. Second, it is suitable for any traditional PS plate, using conventional developing machines and processing chemicals (chemical-free plate materials have been launched), can be used in bright room strips， easy to operate under the file. Third, without changing the existing hardware configuration, 1bit/tiff can be used to format data, and can utilize RIP data without using a special web interface, It can be networked with the existing network environment to realize low-cost operation and the operation and maintenance of the system. The total maintenance cost can be reduced by about 40% compared with the CTP using special plates.
② Improve printing quality and efficiency. Using square dot imaging, with a lower resolution, high-quality printing, and can significantly shorten RIP time and reduce processing, data volume, saving computer system memory, faster exposure speed, etc. square dot edge, the edge is clear, sharp, and faithful to the original. In the case of the same resolution, more can be achieved with high copy quality. Dot-matrix one-to-one correspondence Ps plate digital imaging, which can eliminate copying dot expansion and dirty dots appearing during printing, which is the same as thermal and photosensitive CTP technology out of the same pattern.
③ Reduce printing debugging time and material loss. No need for plate positioning, it is unnecessary to re-make the plate due to inaccurate positioning, to avoid spending a lot of time on printing on the machine. version, which can minimize the time for short-run printing plate change and on-machine debugging, and reduce debugging consumables such as water, paper, and ink are used.
④ Give full play to the potential performance of the traditional PS version. In traditional plate making, due to the film dot gain and dot loss are unavoidable during printing, so the exposure range of the PS version is. It is only 2%-97%, and the controllable range of printing is only about 5%-85%. digital direct. After imaging technology, due to the elimination of dot gain and loss, PS plate can be reproduced excellently, now 1% to 100% of the outlets, printing controllable range has also expanded to 1% -99%.
⑤ Production is more flexible. The platform-style exposure structure has other exposures to supplementary editions. The incomparable advantages of light structure, are for the missing pages, can be empty, first for the existing expose the page of the page, fill in the exposure after the blank file arrives, no need to be like other CTP passively waits for all pages to arrive before being exposed. And can be printed on 2 smaller versions exposed at the same time. In addition, the positioning pin can be flexibly adapted to different positioning systems replacement and can use telescopic pins or three-pin positioning according to customer needs system.
⑥The selection of printing plates is flexible. For different jobs, both the negative plate and the positive version can be used, and the choice of the initiative is completely controlled by the customer. general text. For content-based prints (plate coverage less than 50%), use negative graphics Regular PS plates (Type N); if the image area on the printing plate is large (such as commercial printing, printing plate coverage is greater than 50%), or some special ink corrosion l strong (such as UV ink), Positive type Ps plate (P-type, strong chemical corrosion resistance, high printing force) can be used, which is this saves time and is more efficient.
⑦ Fast, stable, and smooth integration with the traditional PS plate printing process. PS version the ability of machine printing and image reproduction has been tested by the market for a long time and has been recognized. Craftsmanship has been perfected and has been used most widely in the printing industry. Introduce CTcP can continue to use the original plate processor and developer solution; and can print to reduce downtime for plate changeovers. The original ink balance, printing pressure, and other printing parameters are not needed to retest. It not only ensures the stability of printing but also ensures the economy and high benefits.
