(1)Thermal ctp aluminum plate usually has a higher running resistance than PS plate. thermal ctp aluminum plate is mostly used in commercial printing, high-grade and exquisite color printing requires fine and uniform grit, which requires high-quality aluminum plate with high strength and fine grit on the surface of the board as the support. At present, all thermal CTP aluminum plates are used to produce thermal CTP plates.
(2)Surface Roughening Treatment On the advanced large-scale reel-type continuous PS plate production line, the aluminum plate base is chemically treated with an advanced electrolytic oxidation process to form a multi-layer fine and uniform grit layer. Electrolysis and oxidizing liquids all adopt the process of automatic detection and automatic replenishment.



In order to ensure the uniformity of the surface treatment of the aluminum plate base.

(3)Fast connection In order to improve the bonding fastness between the heat-sensitive resin layer and the aluminum plate base, to ensure that the product has high printing resistance, a connection layer is first applied after the plate base is gritted.
(4) Resin layer thermal ctp aluminum plate with good heat sensitivity According to the new principle of thermal acid-promoting cross-linking imaging, a series of new functional resins are synthesized and screened, and the best combination is selected from them, so that the plate has good properties. thermal performance.

(5) Spectral absorption band of thermal resin layer thermal ctp aluminum plate adopts special light-to-heat conversion material to ensure the absorption of the plate
The efficiency of thermal energy is high, and the operation performance of the bright room is good.
(6)Has good dot reproducibility thermal ctp aluminum plate has a certain threshold requirement, the accepted exposure does not reach the exposure threshold
At this time, the chemicals in the resin layer do not react; the cross-linking reaction occurs only when the threshold is reached, so the resulting printing plate has very sharp dot edges.
The layers of text and images are clear and delicate, the dots are not enlarged, and the ink adaptability is good, and the printed products are rich in color.
(7)The thermal layer of thermal ctp aluminum plate with good ink affinity adopts special functional resin and adds special ink affinity additives, so the printing plate made of this plate has excellent ink affinity and fast ink Balance function.
(8) High printing resistance of printing plate The coating of thermal ctp aluminum plate has good wear resistance due to the selected resin, so the printing plate made of this plate has the characteristics of high printing resistance. Plates made under the recommended conditions of use have a durability of 200,000 impressions; after baking the plate can reach 1 million impressions.
(9) No dirt on thermal ctp aluminum plate, after developing and processing, the blank part is clean, the water retention performance is good, and it is not dirty during printing.
