Thermal and visible CTP systems have been the focus of debate. First applied to the CTP is the visible light imaging technology, the introduction of visible light direct imaging equipment such as the Creo Platesetter 3244 makes it possible to set off the first round of CTP buying climax around 1994. However, with the advent of the first thermal imaging system in 1996, new changes have taken place in the CTP market. Thermal plate technology seems to be more attractive to printers, and many experts believe that the thermal plate is the future direction of development.
Immediately after thermal technology was introduced, early-stage CTP-ready printers upgraded almost everything from visible to thermal. Eight years later, although the promotion of purple laser CTP is strong, the choice of thermal is still the trend. This is because there is no change in the underlying reasons for driving India to invest in CTP. First of all, in order to reduce the production process, save time and money, this is what any CTP can do. Second, but also more important reason is to eliminate the variable factors in the imaging process of the printing plate. These variable factors will directly affect the printing factory's most costly sector - the printing shop, including longer adjustment preparation time, increased material loss, inaccurate proofing resulting in poor print quality, inability to guarantee accurate screening, and unstable print quality. In short, the direct consequences of plate imaging instability are higher costs, reduced profitability, and lower customer satisfaction.
Thermal sensitivity is superior to visible light CTP because the visible light plate uses a photosensitive coating, whereas the heat-sensitive coating provides a binary imaging mode that will not be exposed until a critical value. If thermal energy is insufficient, the plate is not imaged. Once the energy reaches the threshold, it causes a phase change, which causes a chemical decomposition reaction of the coating, which means that there is little possibility of underexposure or overexposure. In the past 100 years, dual imaging is the goal of most prepress R&D departments, and the high energy of thermal imaging has made this goal a reality. Therefore, the imaging of the thermal CTP system is more stable.
Visible light plates are sensitive because they can be imaged at very low energy exposures. The weak exposure energy can make subtle changes to the emulsion, and this subtle change can be infinitely amplified when the plate is processed. As long as the plate is manufactured, stored, temperature, humidity, or a slight over- or under-exposure in the exposure during processing, it can have a serious effect on the imaging area, making the image larger or smaller.
The thermal plate coating does not react to light energy and does not require darkroom operation. In addition to the duality of the thermal CTP, there are other powerful features. It is the only technology that can image on three printing methods (offset, flexo, and gravure). Thermal imaging technology is used in most digital offset presses including Heidelberg, Komori, Manroland and KBA. In addition, the thermal imaging technology in addition to the exposure of the plate, you can also expose the proofing media, and more importantly, it can be used to expose the plate, which is the next major development direction before printing. Visible light CTP plates require chemical agents for platelet printing, direct thermal laser imaging without relying on chemical rinsing, eliminating the effects of variable factors, ensuring plate stability, image integrity, and repeatability.
Last year, the sales of thermal platesetters developed at a rapid rate, reaching 64% of all global sales. The installed capacity of thermal devices reached 56%, and thermal plates accounted for 68% of the CTP plates. Lower plate and equipment prices, manufacturers' investment in R&D, and the booming second-hand mobile phone market, in addition to lower machine prices, the thermal system operating costs are also low. However, the new purple laser products have been greatly improved, mainly the use of solid-state diode laser head violet laser, compared to the past, the price of gaseous laser head is relatively cheaper. But when market speculation subsides, you will eventually find that although the violet laser is the ideal wavelength for future visible light imaging, it does not represent the progress of the printing industry in terms of thermal sensitivity and does not bring real benefits to the printer. In short, the imaging or flushing problems caused by violet laser imaging are the reason why the printing industry switched from visible light to heat-sensitive eight years ago.
