The CTP chemical-free establishment of the hot melt office uses hot melt technology, which can be used on any CTP thermal plate-making machine (830nm). The base of the plate is a standard electrochemical frosted and anodized aluminum substrate. The plate has a single coating, and the coating liquid contains ink-friendly hot-melt particles. The particles are small enough to receive high-intensity laser beams.
The research and development of plate technology has always been the core of CTP. The chemical-free hot-melt plate is one of the development directions of CTP green environmental protection plate materials. It has breakthrough developments in printing quality, process, environmental protection, and cost reduction.
1. The process is simplified and the process is single
The CTP chemical-free hot-melt plate-making process can save many traditional plate-making processes, and is conducive to environmental protection. In the process of operation, there are no harsh printing conditions and control data, and the entire plate-making process is singularized. The produced printing plate has stable effect and precise contrast sharpness, which can almost achieve the effect of re-copying the printing plate for many times and the quality of the printing plate is normalized.
2. Reducing costs is conducive to environmental protection
Through practice comparison, the use of traditional CTP version requires thousands of gallons of water, developer, and fixing solution, and the chemical-free hot-melt version uses only 5 liters of water-based glue per month, completely eliminating the cost of the treatment of potion and potion waste liquid. . This chemical plate-making system is very conducive to environmental protection, saving users thousands of dollars a year, greatly reducing the cost of plate-making.
In addition, because the CTP chemical-free hot-melt plate process has a simple simplification process, from the plate making to the machine printing, the use of the CTP chemical-free hot-melt plate process takes only 6 minutes, compared to the traditional printing plate which takes 30 minutes. Over a long period of time, the entire plate-making cycle is greatly shortened, saving time and electricity, which is beneficial to environmental protection.
3. High plate-making efficiency and exquisite prints
In the printing workshop, the printing workers are very clear that the quality of the printing plates is related to the quality of the printed products. In fact, in the morning printing operation, the quality of the printed matter is crucial.
The aluminum base of the CTP chemical-free hot-melt version is frosted and anodized. It has good offset printing characteristics and a large wetting tolerance. In addition, it is glued before the printing machine to reduce the sensitivity of the surface and make it dirty, so the plate has a high print resistance and is suitable for rapid printing. The CTP chemical-free hot-melt version is mainly for four-color and eight-color offset presses.
It has been proved by practice in recent years that the printing plate made by CTP chemical-free hot-melt office is extremely accurate, and can achieve 2% -98% dot reproduction. When using traditional mesh 175 lines / inch, it is on the printing machine. The water-ink balance is very stable. The printing plate produced in the printing workshop can be directly printed on the machine like a traditional printing plate. It can make the printer run up to 100,000 prints for a long time, and there is almost no fluctuation in print quality.
CTP chemical-free hot-melt plate is a major direction of sheet development
As a big printing consumer country, China should step into the forefront of the printing world as soon as possible and master advanced technology. Nowadays, energy conservation, consumption reduction and emission reduction, and strengthening environmental protection awareness are urgent work requirements. Undoubtedly, the CTP chemical-free hot-melt version with the appearance of a new type of energy-saving and environmentally friendly sheet has many advantages. First, there is no need to purchase various types of chemical potions for plate-making; second, because there is no erosion of the equipment on the equipment, the investment in equipment maintenance is reduced; Processes such as chemical development, fixing, and flushing save time, effort, and water; fifth, due to the simplification of operations, it can reduce personnel and labor costs; sixth; the process is simplified, which can ensure the cleanliness and cleanliness of the operating room; seventh, improve the printed products Accuracy, to achieve the best visual effects of printed products. It can be said that the CTP chemical-free hot-melt plate is a direction for the development of printed plates, and it is worthy of research and expansion by the Chinese.
