In high-end applications such as long run commercial printing and packaging printing, the imaging accuracy, durability, and environmental adaptability of CTP plates directly determine printing efficiency and finished product quality. Double layer thermal CTP plates, as a core product developed to meet the needs of long running printing, achieve performance breakthroughs based on thermal imaging technology through a unique layered structure design and precise material formulation, becoming the preferred solution that balances production efficiency and printing quality. Based on years of R&D and production experience, we HC can offer durable thermal CTP plates double layer for long running printing.

The double layer structure design is the core technical highlight of thermal CTP plates product. Through the functional partitioning of the photosensitive layer and the base layer, it effectively solves the performance bottleneck of traditional single layer thermal CTP plates in high-volume printing. The photosensitive layer uses a self-developed high-sensitivity thermal imaging formula with a photosensitivity of 2.0 mJ/cm², compatible with mainstream 830nm infrared laser CTP equipment. The imaging speed is 15% faster than conventional products, meeting the high-efficiency plate-making needs of mass production. Meanwhile, the nano-scale titanium dioxide dispersion system added to the photosensitive layer enables the plate to achieve a dot reproduction accuracy of 1%-99%, maintaining smooth dot edges even at 200lpi screening, effectively enhancing the detail of printed materials.

The optimized design of the base coating further strengthens the double layer thermal CTP plate's durability and compatibility. Our factory uses a special polyurethane resin and aluminum-based bonding technology, increasing the adhesion between the base coating and the anodized aluminum plate base by 30%. Combined with the cross-linking curing system of the photosensitive layer, the CTP plate's printing durability stably reaches 300,000-500,000 impressions, performing particularly well in large-area solid and long-run jobs in packaging printing. Notably, this base coating possesses excellent chemical resistance, compatible with both conventional alcohol-based dampening solutions and environmentally friendly alcohol-free dampening solutions, maintaining stable performance in dampening solution environments with pH values of 4.5-8.5, reducing consumable adaptation costs for printing companies.

In terms of core specifications, the thermal CTP plates double layer for long run printing covers mainstream application sizes, including standard formats such as 830mm×1160mm and 1030mm×1450mm. Custom formats can also be made to meet specific customer needs. Aluminum base thicknesses are available in 0.15mm, 0.20mm, and 0.30mm to meet the double layer thermal CTP plate mounting requirements of various printing equipment. The thermal CTP plate surface roughness Ra is controlled between 0.25-0.35μm, ensuring uniform ink transfer while avoiding dot loss due to excessive roughness. Furthermore, the product uses a chromium-free processing method, complies with EU RoHS environmental standards, and has a shelf life of up to 12 months (at 25℃ and 50% relative humidity), facilitating inventory management for printing companies.

In practical applications, the advantages of this double layer thermal CTP plate have been verified by numerous large printing companies. A packaging and printing company used this product to print long-run food packaging jobs, achieving a single-plate print run of 450,000 impressions. The color consistency deviation of the printed products was controlled within ΔE≤1.5, reducing the scrap rate by 2.3% compared to using conventional plates. A commercial printing company used it for large-volume journal printing, increasing plate-making efficiency by 20% and raising the daily plate production from 80 sets to 96 sets, effectively shortening the production cycle. These application cases fully demonstrate that this product, through precise matching of its technical characteristics, achieves multiple values: efficient plate-making, stable printing, and cost reduction, providing a reliable plate solution for large-volume printing production.

Double layer thermal CTP plates, with their core advantages of efficient imaging, high-precision dot reproduction, high printing durability, and environmental compatibility, precisely meet the technical requirements of long run printing. Our factory, through continuous material research and development and process optimization, ensures stable and controllable product performance and a complete specification system. We can provide customized solutions for different printing scenarios, helping printing companies enhance their core competitiveness.
