Brief Description of Plate Technology

The printing plate is an important part of the printing supply chain, and it also determines the quality of the printing. Therefore, when the printing buyer purchases the printing plate, he must understand its technical characteristics and development trends, and according to Make your own decisions and make the right decisions.

Chemical-free and plate-free processing

Perhaps many people want to know: What is the difference between chemical-free printing plates and plate-free processing? The true process-free plates can be developed directly during job preparation without any intermediate links between plate imaging and on-machine printing. With the start of the printing press, the non-graphic part of the printing plate will be automatically removed. At present, the common non-processing plates include Kodak Thermal Direct, Presstek's Aurora Pro and Fuji Brillia HD Pro-T.

The chemical-free processing plates are after imaging, the non-graphic part of the printing plate is removed by a colloidal solution. Since the solution circulates inside the cleaning unit, it does not cause any pollution to the environment. The most common chemical-free processing plates are Agfa's Azura V, Fuji's HD-Pro-V and TechNova's VioGreen CTP plates.

There are several reasons why chemical-free printing plates are more popular than free-handling plates. The first is that there are still some deficiencies in the use of plate-free plates. For example, there are no contrasts, and it is impossible to find errors before printing on the machine. Scratching ability is poor, it is not suitable for the automatic plate unit on the plate cylinder, it is easy to mix the roller with the chemicals on the printing machine, it is sensitive to sunlight and it is not easy to store, which brings a lot of inconvenience to the actual production. Secondly, the chemical-free processing plate can fully meet people's production needs. It not only has high sensitivity, but also can meet the requirements of practicality of newspaper printing and printing service organizations, reduce the boot waste of the printing press, and has a higher resistance to printing. Resolution, but also allows people to see the image on the plate before printing on the machine, which can effectively reduce the occurrence of errors.

Thermal and violet laser CTP

For many years, plate manufacturers have been arguing about the advantages and disadvantages of different imaging technologies. Those who support the thermal technology believe that its greatest advantage is the adoption of a binary production process. A laser spot is either exposed or not exposed. However, the problem is that its imaging speed is slow, and it has high requirements for the cost and service life of high-power lasers. Violet Laser CTP adopts popular and low-cost laser diode technology, but its image quality cannot match that of the thermal CTP, so it is not suitable for high-quality print reproduction.

However, with the advent of FFEI's next-generation violet laser platesetters and Fujifilm and TechNova high-quality violet laser plates, there has been a reduction in the debate over thermal and violet laser technologies.

TechNova and Fujifilm claim that the quality of next-generation printing plates is comparable to that of traditional thermal printing plates, and that the performance of on-press printing should be even better. TechNova said its Viostar and VioGreen violet laser plates can reproduce 10 micron dots on the Viostar (FFEI) platesetter.

UV CTP (also known as CTcP)

This technology has been around for many years. The most prominent feature of UV CTP or CTcP is the replacement of expensive thermal and violet laser plates with high-speed traditional negative and positive PS plates. The current UV platesetter (by BasysPrint, Luscher Laser diodes are provided by both Cron and other companies, which can increase the output accuracy and output of the device, but the image resolution and print quality cannot be compared with violet lasers and thermal plates.

Given the high cost of UV platesetters, the cost can only be recovered (at least 2000 to 3,000 m 2 /month) when the user's monthly production reaches a certain level.

As the price gap between thermal, violet and PS versions shrinks, this balance point will continue to grow. UV CTP is currently the primary choice for many large plate service organizations.

Silver salt printing plate

Silver halide technology is a time-honored platemaking technology that can provide users with surprising exposure speeds and excellent image quality, but in the CTP, this technology has reached a peak, it is difficult to have new . This is mainly because the printing plates must be developed, and it is impossible to provide users with solutions that are free from treatment or chemical treatment, and this will certainly have a certain impact on the environment. For some high-quality prints, printing plants are still willing to use silver salt plates. However, the heyday of silver halides has passed. People now focus on violet laser, thermal and inkjet.

Future trends

A few years ago, a number of plate manufacturers also believed that the violet laser's chemical-free processing of plates and the handling of plate-free technologies was a dream that could not be realized and that commercial applications could never be realized. But it turns out they were wrong. At Pamex 2010, held earlier this year, many plate manufacturers demonstrated that chemical-free processing of violet laser plates is the future of the printing industry. At the same time, the inkjet technology is also rapidly rising at an incredible speed. The inkjet CTP system can directly image on the metal plate, and does not require photosensitive coating, which is very worthy of attention.

The future of CTP

Faster, higher-productivity systems will continue to emerge, and a new generation of low-cost, energy-efficient laser diodes will continue to be in the spotlight. Large arrays of laser diodes will simplify the production process of plates and increase production speeds. The development of on-machine imaging technology will also bring some influence to the future of the CTP market.
