Map Paper Puzzle The advantages and disadvantages of CTcP plate making technology

 

CTcP has many advantages, the most obvious is to improve production efficiency, save time and reduce production costs. However, the degree to which CTcP can be an advantage is also related to the degree of digital technology mastery of the printing company. From traditional plate making to computer direct plate making, there are many important factors affecting the time and cost.

 

The advantages of current CTcP technology

1. Significant economy

a) Simplified process flow. The CTcP system reduces the process of film production and plate printing in the traditional process, and saves the consumables and related costs.

 

b) Use traditional PS plate material. In various CTP systems, specialized 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, which is the general PS plate material used in the current process. Compared with other CTP technologies, the CTcP system has a larger price advantage because of the use of traditional PS plate and developer and potion, and can achieve low cost operation of production.

 

c) The equipment is simple. The CTcP system uses UV plate material, so it can be easily operated under open room conditions, and companies can introduce the system without changing other operating environments before press. Its light source uses ultraviolet lamps, the life 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, improve the printing quality

CTcP system inherits the advantages of CTP system - no need to output film, but also can realize the computer directly plate making. In this way, film materials and rinsing materials can be saved, and manual assembling time can be saved. Many users of CTcP have experience with film printing, and without the need for film, the print quality of the printed matter is significantly improved, because the image and dot are not affected by the quality attenuation in the traditional prepress process. The quality of the printing plate after printing is better, because the influencing factors such as dust and scratches on the film are no longer present, and the positioning is more accurate. In short, the dots obtained by CTcP platemaking technology are the first generation of dots passed directly to the plate, with clean, sharp edges and faithful originals.

 

3. Fast and stable integration into the traditional plate making process

Since the CTcP system is still using the ordinary PS plate material familiar to the printing house, the producer can undoubtedly continue to use the various pharmaceutical liquids, developing equipment and punching devices in the original plate making process to achieve a good compatibility between the plate making system and the printing press. Printing companies do not need to worry about the problems caused by changes in printing suitability, and do not need to spend a lot of time and energy to complete the matching work of the plate and the printing press. CTcP technology not only simplifies the original lengthy process, but also preserves the traditional operating habits and printing adaptability to the maximum extent, and provides the best way to complete the production task stably and efficiently.

 

In connection with other prepress systems, CTcP also has its own unique features. All UV-Setter series CTcP platemakers are equipped with an open 1-BitTiff interface. No matter what device and workflow as long as the output file is 1-BitTiff format, it can be perfectly integrated with the CTcP plate maker. For printing companies, this means that operators can quickly and easily implement the digital plate making process without making additional investments. In addition, the simple equipment and open workflow have more advantages for future maintenance and upgrading.

 

4. Reduce printing debugging time and material loss

Because there is no need for plate positioning, the quality of the plate is better, and it will not need to be re-made due to inaccurate positioning, avoiding the need to spend a lot of time correcting the plate when printing on the machine. With the increasing number of short editions in the entire printing industry, changing editions and commissioning on the machine have become regular work. Reduce printing debugging time, can significantly save time and cost. CTcP platemaking is more accurate than traditional analog platemaking, so it reduces the waste of water, paper, ink and other consumables during commissioning.

 

5. Easy to operate

All UV materials (plates or proofing materials) can be operated in the bright room, while the blue and violet laser needs to operate in a dark room, a weak light or yellow light source environment, which can easily expose a variety of sizes of plates, and can also handle multiple plates at the same time, which can be exposed multiple times on the same plate.

 

6. Printing customers are more satisfied

Printing customers are more satisfied with the quality of printed matter, and the printing production time is shorter, which means that the delivery is more timely, reducing the operating costs of the factory, and giving the printing company an advantage in the fierce market competition.

 

7. The advantages of UV direct plate making

The use of 360 ~ 450nm UV light source exposure, means that you can use the conventional PS plate in the direct plate making process, which is the printing material used by printing manufacturers for many years, familiar with its performance and processing processes, mature technology, and PS plate than thermal CTP plate, purple laser plate cheaper, PS plate is the world's printing industry the most used printing plate. There is no need to train the printer because they already know the properties of the plate.

 

The shortcomings of current CTcP technology

Of course, CTcP plate making system also has its shortcomings that can not be ignored. Although the CTcP plate making system can realize the direct computer plate making on the ordinary PS plate, the speed of plate making is not satisfactory because the sensitivity of the ordinary PS plate is generally low. In order to cooperate with the promotion of CTcP system, Agfa, Fujifilm, Kodak and other companies have launched a series of plate materials with high sensitivity, so that the CTcP plate making speed is close to the thermal CTP plate making speed.

 

However, in order to make CTcP more competitive, the platemaking speed needs to be further improved. In addition, DMD is the core part of the platemaking machine, in order to improve the resolution, the microlens has been increased from the original 300,000, 800,000 to the current 1.3 million, DMD is a very precise part, which brings certain difficulties to its daily maintenance and maintenance. The failure of any microlens will affect the imaging effect to a certain extent. Once the DMD has a big problem, it needs to be replaced, which not only affects the normal operation of the machine, but also costs a lot.
