CTcP has many advantages, the most obvious is to improve production efficiency, save time and reduce production costs. However, the extent to which CTcP can reflect its advantages also depends on the printing company's mastery of digital technology. The transition from traditional plate making to computer direct plate making has many important factors in terms of time and cost.
Advantages of current CTcP technology
1. Significant economy
a) Simplified the process flow. The CTcP system reduces the process of film production and printing in the traditional process, saving consumables and related costs.
b) Use traditional PS plates. In various CTP systems, special CTP plates are inevitably required, and their prices are very expensive. The plate material used in CTcP plate-making is a cheap conventional printing plate material, that is, the general PS plate material used in the current process. Compared with other CTP technologies, the CTcP system has a large price advantage due to the use of traditional PS plates, developing machines, and potions, and can achieve low-cost operation of production.
c) The equipment is simple. The CTcP system uses UV-sensitive plate materials, so it can be easily operated in bright room conditions, and companies can also introduce the system without changing other operating environments before printing. Its light source uses ultraviolet lamps, and the lifespan has been increased to 2500 hours, and the price is less than 1/10 of the laser light source, so the operation and maintenance cost of the equipment is very low.
2. No need to output film, which improves printing quality
The CTcP system inherits the advantages of the CTP system ─ without the need to output film, the computer can also directly make plates. In this way, film materials and processing materials can be saved, and time for manual imposition is saved. Many users who use CTcP have the experience of film printing. After no film is needed, the printing quality of the printed matter has improved significantly because the image and dots are not affected by the quality degradation in the traditional pre-press process. The plate after printing is of better quality, because the influencing factors such as dust and scratches on the film no longer exist, and the positioning is more accurate. In short, the dots obtained by CTcP plate-making technology are the first generation of dots directly transferred to the printing plate, with clean and sharp edges and faithful originals.
3. Quickly and steadily integrate into the traditional plate-making process
Since the CTcP system still uses ordinary PS plates familiar to printing houses, producers can undoubtedly continue to use the various chemical solutions, developing equipment and punching devices in the original plate-making process to achieve a good plate-making system and Printing machine compatible. Printing companies do not need to worry about the problems caused by changes in printing suitability, and they do not need to spend a lot of time and energy to complete the matching work between plates and printing machines. CTcP technology not only simplifies the original long process flow, but also retains the traditional operating habits and printing suitability to the greatest extent, and provides the best way to complete production tasks stably and efficiently.
In contact with other prepress systems, CTcP also has its own unique features. All UV-Setter series CTcP platesetters are equipped with an open 1-BitTiff interface. No matter what equipment and workflow, as long as the output file is in 1-BitTiff format, it can be perfectly integrated with the CTcP plate-making machine. For printing companies, this means that operators can implement the digital platemaking process quickly and easily without additional investment. In addition, simple equipment and open workflow have more advantages for future maintenance and upgrades.
4. Reduce printing debugging time and material loss
Since the positioning of the printing plate is not required, the quality of the printing plate is better, and there is no need to remake the plate due to inaccurate positioning, avoiding a lot of time to proofread when printing on the machine. With more and more short-lived work in the entire printing industry, changing the plate and debugging on the machine have become regular tasks. Reducing printing and debugging time can save time and cost. CTcP plate-making is more accurate than traditional analog plate-making, so the waste of water, paper, ink and other consumables is reduced when debugging on the machine.
5. Simple operation
All UV materials (printing plates or proofing materials) can be operated in the bright room, and the blue-violet laser needs to be operated in a dark room, a weak light or yellow light source environment, which can easily print various specifications and sizes. It can also process multiple plates at the same time, and can be exposed multiple times on the same plate.
6. Printing customers are more satisfied
Printing customers are more satisfied with the quality of printing, and the production time of printing is shorter, which means more timely delivery, lowering the cost of factory operations, and making printing companies take the lead in the fierce market competition.
7. Advantages of UV plate making directly
Exposure by UV light source of 360-450nm means that the conventional PS plate can be used in the direct plate-making process. This is a printing plate material used by printers for many years. It is familiar with its performance and processing procedures. The technology is mature and the PS plate is more thermally sensitive. CTP plate material and purple laser plate material are cheaper. PS plate is the most used printing plate material in the printing industry in the world. There is no need to train printing staff because they already know the performance of this plate.
The shortcomings of the current CTcP technology
Of course, the CTcP plate-making system also has its shortcomings that cannot be ignored. Although the CTcP plate-making system can realize computer-to-plate directly on the ordinary PS plate, the sensitivity of the ordinary PS plate is generally low, and the plate-making speed is not satisfactory. In order to cooperate with the promotion of the CTcP system, Agfa, Fuji, Kodak and other companies have successively launched a series of high-sensitivity plate materials, making the CTcP plate-making speed close to the thermal CTP plate-making speed.
But in order to make CTcP more competitive, the plate-making speed needs to be further improved. In addition, DMD is the core component of the plate-making machine. In order to improve the resolution, the micro lens has been increased from the original 300,000 and 800,000 to the current 1.3 million. It can be seen that DMD is a very precise component, which gives it daily maintenance and maintenance Bring some difficulties. The failure of any micro lens will affect the imaging effect to a certain extent. Once the DMD has a major problem, it needs to be replaced, which not only affects the normal operation of the machine, but also costs a lot.
