The Advantage of Thermal CTP Plate
Thermal CTP technology and its plates are favored by printing companies for their unique features such as high imaging quality. Widely favored by the brush industry and considered to be one of the most promising technologies.
There are some advantages of Thermal CTP Plate
Bright room operation
This is an important feature different from photosensitive imaging materials. Because the heat-sensitive plate is imaged by thermal imaging technology, and its photosensitive area is between 830 and 1064nm, which is outside the visible spectrum, the operator can control it under the eyes of yellow light or filtered ultraviolet rays—that is, under the conditions of the bright room. Every technological process improves the working environment. This is more convenient and reliable for the printing factory, greatly reduces the requirements of the process operation on the production environment and labor intensity, and reduces the loss of production. For photosensitive plates, although darkroom operation is avoided, it is still necessary to work under red, green, or yellow light conditions.
Reasonable structure
At present, the structure of CTP is mainly divided into three types: inner drum type, outer drum type, and platform type. The heat-sensitive CTP technology is mainly an external drum type. This structure makes the printing plate on the printing press as if it is wrapped in a cylinder, and the coating is outward to minimize the deformation of the dots, which makes it easier to handle large-format printing plates.
High-resolution
Due to the high heat transfer performance of the laser used in the exposure of the heat-sensitive plate, the contrast in the lateral position is very large during heating, which makes it easy to have differences in thermal curing between the graphic and non-graphic parts. Therefore, thermal CTP The resolution of the plate is considered to be the highest among all CTP plates, so as to ensure the quality of the printing plate and print high-quality printed products.
High image quality
(1) The thermal plate can ensure the integrity of the information during thermal exposure, making the printing quality more stable. This is because the prerequisite for forming an image on a heat-sensitive plate is sufficient to heat energy, that is, the initial heat energy threshold. Any energy value below the threshold will not produce any image on the plate, and any energy value above the threshold will not expand the area of the image already formed on the plate. This is the only technology that can control the predictable results so that the printing dots can be controlled before printing, and the fully controllable digitalization can be completely realized so that the printing colors can be completely consistent when the plate is repeated many times, and it can break through the traditional plate making in frequency modulation crystal net, etc. High-precision printing is limited in printing and printing, resulting in higher-quality printing results. For other CTP plates, due to the constraints of developing conditions, etc., the dot size change is greatly affected by the back-end flushing conditions, which will show corresponding fluctuations, and the printing performance is not good.
(2) Since the thermal CTP plate is imaged by thermal imaging technology. It can restore 2001pi, 1% to 99% of the dots, unlike the photosensitive plate, which is prone to blurring due to environmental problems. Exposure is not thorough, halftone dots often appear as halo, and so on. Thermal plates have good image quality and high printing durability and can restore image levels very well for negative or positive plates.
(3) The quality of the printing plate is high, and the edges are sharp and clear due to the solid dots of the heat-sensitive CTP printing plate. This will make it easier to achieve ink balance when printing. Conducive to dot control, thus leading to high-quality printed matter.
(4)The heat-sensitive square dot technology allows FM random screening in the production environment so that the printed color is almost not affected by the color tone of the paper, and because the light spot diameter of the heat-sensitive CTP can be as small as 10 m, it can be printed Very high-quality fine print.
(5) In addition, since the heat-sensitive ctp plate is exposed to a laser beam, the laser light spot is very digital just like the heat-sensitive printing plate. Combining the mesh adjustment dots generated by the two can avoid the common pair exposure in the daily production environment, development, plate-making, and half-dot expansion or loss;
All these are beyond the reach of photosensitive CTP plates. Overall, thermal CTP technology and printing plates can provide stable quality, bright colors, and clear dots. This is undoubtedly for printing companies who want to increase productivity and win in the fierce competition. Thermal CTP is a wise choice.
High durability
Generally speaking, the heat-sensitive CTP plate can reach more than 200,000 prints without plate-baking treatment. If it is processed by plate-baking, the printing volume can reach more than 1 million prints, or even more than 2 million prints. Printing rates will not only benefit long runs but will also result in more consistent print quality for short and medium runs. The printing life of the silver salt plate in photosensitive CTP is generally below 100,000 impressions, even if the photopolymerization plate is baked, its printing resistance can only reach 800,000 impressions. The sensitive ctp version is far behind.
Environmentally friendly
The thermosensitive CTP plate is imaged using the principle of thermal imaging technology, thus avoiding the use of silver salt materials in the process of photosensitive imaging due to development, washing, etc., and preventing the production of a large amount of chemical developer solution, which will cause serious pollution to the environment. The development and use of heat-sensitive plates without chemical washing or treatment will further eliminate environmental pollution in the plate-making process.
Wider application
At present, it is generally believed that thermal CTP technology has great advantages in terms of quality, inking performance, and printing force. It is more suitable for commercial printing, book printing, packaging and decoration printing, and other fields, especially in recent years. The proportion of commercial printing is gradually increasing, and it has become the theme of CTP plate consumption.
