Positive thermal CTP plate is a layer of sand mesh structure formed by electrolytic coarsening on the upper surface of aluminum substrate, a layer of alumina hydrophilic layer formed by anodic oxidation on the surface of sand mesh structure, and a layer of thermal imaging composition coated on the surface of alumina hydrophilic layer, wherein the sand mesh depth of sand mesh structure is 2.0-2.6 μm. The density is 0.4-0.5 μm. The longitudinal total density is 0.025-0.030 μ m.
 


Positive thermal CTP plate is a new type of positive image thermal CTP plate, which can better achieve dot (1-99%) reduction. It is used for computer direct plate making, with high resolution, high image accuracy, high reliability and repeatability, and can realize high quality digital printing.
 
So far, in the selection of PS/CTP plate base material, there is no better material to replace aluminum plate. With the vigorous development of China's printing industry, the market and production capacity of aluminum plate base is growing rapidly.
