Overview of CTP plates: more products, larger market

at present, the three technologies of silver salt visible light type, non silver salt visible light photosensitive resin and thermal imaging of computer direct plate making imaging technology have been recognized by the market, and many companies provide CTP plates using these three imaging technologies. These CTP plate suppliers continue to compete for market share

in the United States, thermal plates dominate the CTP market, accounting for 75% of the CTP market share. With small printing companies purchasing low-cost direct plate making machines, the consumption of CTP plates that sense visible light continues to grow. With the launch of AGFA's new generation of violet laser plates, Fuji and MCC (Mitsubishi Chemical Corporation) are also about to promote 30MW photosensitive resin plates that can be used in turns as spare parts, which will break the market balance between visible light sensitive plates and thermal sensitive plates

thermal plates are favored

from the global market and show good separation selectivity for adsorption and separation of CO2 and N2. A trend of CTP development is to turn to thermal plates. The biggest feature of thermal plates is that they need not be washed and baked. Agfa company and pressek company are the first to launch the heat sensitive plate without washing treatment. The technology of Fuji and KPG is also under development. For the topic of not baking, Fuji company believes that many printers are unwilling to use the equipment for baking printing plates

market response

the swood plate launched by KPG is a negative type plate, which does not need preheating or baking. The dynamic range is 1% - 99% at 175lpi and 2% - 98% at 200lpi. Swood plate can tolerate the effect of alcohol fountain solution

in order to achieve the printing resistance of 400000 prints without baking, the swood plate adopts a new coating technology, which can resist a variety of chemicals, including solvents, detergents and fountain solutions in UV inks and electron beam drying inks. Swood plates have greater tolerance on the printing machine, improved ink receptivity, reduced ink consumption, larger density range of printed products, and better color stability

another new product of thermal plate produced by KPG company is thermal gold, which is the next generation product of thermal printing plate/830 of KPG company. Thermal gold plate has a printing resistance of more than 1million prints when it is baked, and 150000 prints when it is not baked. Imaging technology eliminates the disadvantages of point edge expansion, and the excess laser energy will not have any impact on the size and shape of the point. We can master the performance of the sample and make use of it without using the experimental curve

double metal digital plate

printing developments Inc. (PDI) company's double metal prism plate without baking continues to sell well in the CTP market. At present, the printing knife of eclipse, an aluminum based photosensitive resin digital plate, can print up to 1 million without preheating and post baking. These digital plates use a photosensitive resin patented by the company for imaging without ablation, and the point reproduction at 140lpi reaches 1% - 98%. The chemicals involved in eclipse plate making are harmless and non corrosive. The chemicals produced in the use of PRISMA plates can be 100% recycled

the extreme 2G plate of Lastra America Corporation is a 830nm thermal plate, which does not need to reduce the energy consumption of 100 million tons of standard coal, preheating or post baking process, and the printing resistance is close to 1million. After baking, the printing resistance exceeds 1million prints, and the resolution reaches 2% - 98% at 200lpi. In some direct plate making equipment, point reproduction can reach 1% - 99%

the plate base of Thermolite plus plate is an aluminum plate after electrochemical sanding and anodizing, which is very similar to the traditional PS plate. When printing, first wet the printing plate with a wetting system, and then remove the loose coating of the non graphic part with an inking roller. The remaining coating of the non graphic part is transferred to the first few prints that start printing, which shortens the printing preparation time and cleanly removes the remaining coating of the non graphic part

visible light sensitive digital plate

Agfa successfully developed the next generation of visible light sensitive lithostar plus plate. Lithostar ultra is a silver halide CTP plate with three color sensitivities, including violet laser plate products. Lithostar ultra plate adopts high-quality sand mesh treatment and anodized aluminum plate base, which makes the printing plate have strong, predictable and high-quality printability

mitsubishi imaging (MPM) introduced silverdigiplate alpha, a purple laser aluminum plate. Using the patented silver halide technology of Mitsubishi, the point resolution of the plate reaches 2% - 98% at 300lpi, and the printing resistance reaches 200000 prints. The sdp-av plate introduced by Mitsubishi lmaging company for the 400 ~ 430nm purple laser direct plate making machine has a yellow safety light and can be exposed at a high speed when the laser energy is 5MW

new face in the digital plate Market

citiplate provides plates with visible light sensing technology - Aqua LHP system includes non silver salt, negative type photosensitive resin plates, and the photosensitive energy wavelength range is 360 ~ 450nm UV light. Using standard plate washing treatment, the printing plate printing resistance ranges from 20000 to 2million (plates can be baked, or UV light hardening treatment is used to provide printing resistance)

in order to realize the integrity of the workflow, the aqua LHP UV version can be exposed and imaged on a digital plate making machine with UV laser, or on a traditional contact plate printing frame and on a continuous shooting machine
