The CTP, which first appeared on Drupa in 1995, has gradually changed from popular to mature with the ups and downs. From a technical point of view, the most discussed issue is quality. The development and application of photosensitive CTP and thermal CTP and their plates. The application of photosensitive medium violet laser CTP in the newspaper industry has become an indisputable fact, and thermal CTP in commercial printing has also firmly established its foothold. The reason why thermal CTP is widely accepted is inseparable from its own excellent characteristics and high product quality.
â‘ Ease of use. People are tired of operating in the dark room, and the thermal CTP uses infrared lasers to image with heat, and users can safely operate in the bright room.
â‘¡The rationality of the structure. Now the CTP structure is mainly divided into three types: inner drum type, outer drum type and flat table. The thermal CTP is mainly an external drum type. This structure allows the printing plate to be wrapped on the cylinder like a printing machine, with the drug film outward, which minimizes the deformation of the dots and makes it easier to handle large-format printing plates.
â‘¢ Stability of quality. Photosensitive plates are very sensitive to light. Underexposure or overexposure will occur during exposure, halftone dots will appear halo, and they will also be affected by light interference within the machine, making the quality of the publication difficult to control; while thermal plates If you want to generate an image, you must reach the initial thermal energy threshold. Thermal energy higher than the initial threshold will not change the shape of the dot. It is the only technology that can control the predictable results. The quality is easy to control and the publishing quality is stable. After exposure, the printing plate can be extended to 6 months before being developed, without affecting the quality. As (picture 1)
â‘£High quality of printing plate. The dots of the thermal CTP printing plate are solid, and the edges are sharp and clear. It is easier to achieve water-ink balance during printing, which is conducive to dot control and prints high-quality prints. (As shown in Figure 2)
⑤ Savings of consumables. As the competition in the printing market intensifies, saving consumables is disguised profit. The thermal CTP printing plate has the characteristics of solid dots, clear edges, and easy inking. Compared with the traditional PS plate, a smaller amount of ink can achieve normal results and save ink. The printing durability can reach 150,000 to 200,000 prints without baking, and 1 million prints after baking. It is also suitable for matte paper and UV ink printing.
â‘¥ Sustained development. The thermal CTP version is by far the only plate that can be processed without processing. Although it has just been put on the market now, it is very advantageous for investment and environmental protection because the plate is free of washing or only water washing, and it is suitable for existing thermal CTP equipment.
⑦ Extensive selection of materials. Nowadays there are more manufacturers of thermal plates in the market than purple laser plates, and there are also domestic ones, so customers can have more choices and prices are more advantageous.
⑧ Simple and easy to use. Since thermal CTP has so many advantages, how practical is it? Is the operability very good? The answer is of course yes. The thermal CTP, coupled with the advanced digital printing process, can precisely control the expansion and deformation of the dots and the distribution of ink. More importantly, the heat-sensitive plate material can be fully applied to the existing printing environment, and the printing suitability is good (including printing pressure, plate cleaning agent, alcohol concentration and acidity of fountain solution, etc.).
With the development of technology and the maturity of the market, thermal CTP and thermal plate materials, with their strong advantages, will lead the platemaking to bid farewell to the darkroom, and guide the printing industry to digital green printing. An indispensable part of the entire printing process.
