CTP version, free of charge or chemical free?
From the broad angle, the processing-free plate means that after the plate is exposed and imaged on the direct plate-making equipment, it can be printed on the machine without any subsequent processing steps, and of course, it does not require chemical development and rinsing, which is truly free of processing. Plate. However, in a narrow sense, some editions do not need to be developed by a developing machine, but the printing plate is developed by dampening solution after being mounted on the printing machine. For example, the printing plate does not need to be chemically developed after being exposed and imaged on the direct plate-making machine. However, there will be some non-chemical treatment processes, such as the removal of the plate ablation waste, the application of protective coatings, etc., so strictly speaking, this version is not a true no-treatment version. We often see some magazines talking about “no chemical development plateâ€. Some people refer to this type of plate as a no-treatment version. In fact, no chemical development plate means no need to use chemical solution to develop, but still need water. To rinse, therefore, strictly speaking, this type of plate is not a true no-process version.
However, whether it is a no-treatment version or a chemical-free version, most of them have the following advantages: they can reduce the inventory cost, the corresponding labor cost and the waste disposal cost without using chemicals, and are environmentally friendly. At present, more and more printing companies with four-open printing presses have chosen chemical-free CTP plates and equipment for the sake of saving floor space.
Large format CTP
As more and more domestic companies introduce large format multicolor presses.
For large-format printing, printing companies pay more attention to the benefits of printing high-quality prints on a large scale, but with the widening of the large-format printing market, efficiency is also a problem that cannot be ignored. CTP's publishing efficiency is large. A series of problems, such as how to improve the efficiency of the " printing order" of the printing equipment , are on the way.
The larger the format of the printing plate used for large format printing equipment, the more graphic information it contains, the more exposures the CTP device requires, and the effective exposure of the CTP device with the same output resolution. The higher the frequency requirement. Large-format printing equipment should focus on the following two factors when selecting the matching CTP: First, for thermal CTP equipment, in addition to the hardware factors and processing flow of the web, more attention should be paid to the thermal imaging head. The maximum laser output energy; secondly, for the violet laser CTP device, more attention is paid to the output power of the device laser head.
Inkjet CTP
With the improvement of the resolution of inkjet printers and the expansion of printing format, inkjet CTP has started large-scale technology research and development after nearly 20 years of slow technology development, Baoliguang, Fuji, Kodak , Konica, etc. Internationally renowned imaging companies have invested in the development of inkjet CTP equipment and plates. Inkjet printing on bare boards is the focus of research and development by major companies. Because this type of printing inkjet can be directly printed on the machine after curing, it does not need to be wet, fast and environmentally friendly.
It should be said that the internationally renowned inkjet equipment manufacturers have provided the original for the development of inkjet CTP. With the help of the equipment of inkjet equipment suppliers, domestic companies have also started the development of inkjet CTP equipment in recent years. The development of inkjet CTP in China is just beginning, because in recent years, inkjet CTP has gradually been accepted by small and medium-sized printing companies. At the beginning of this century, most printing companies also believe that inkjet CTP is a low-end product. There is not much future for development.
The main reason inkjet CTP is able to develop its line screens has greatly improved, can now do 175 lines / inch high-end print needs, while its price is just platesetter thermal and violet CTP, One-tenth of the price is one-tenth the price of a traditional laser imagesetter. The price of inkjet CTP plate also has a great advantage, only slightly higher than the price of the ordinary PS version.
The development of CTP inkjet market has driven the development of CTP inkjet printing plates. The earliest manufacturer engaged in CTP inkjet printing plate production in China is Beijing Pratt Electronics Co., Ltd., and the current domestic production of inkjet CTP printing plates is larger. Nanjing Jiangya Printing Technology Co., Ltd. has completed two CTP inkjet production lines with an annual production capacity of 2 million square meters. In 2006, the total domestic CTP version produced 20 million square meters. It is expected that in the next few years, inkjet CTP platesetters and inkjet plates should have rapid development. The famous foreign CTP manufacturers may invest a lot of money in the technical research and development and marketing of CTP platesetters. The inkjet CTP will be SMEs set up a fast path to CTP and digital workflows.
