The Requirements of PS Plate on Aluminum Base Plate
Aluminum base plate is the main raw material for PS plate production, accounting for 80% consumption. As aluminum sheet manufacturer, Haomei tells which quality is needed. Learn more!
Offset printing is the main printing method at present. PS plate and CTP pate are the two necessary plates for offset printing. PS plate is made by coating a non-silver photosensitive (thermal) resin layer on aluminum base plate with a thickness of 0.15 mm to 0.5 mm after electrolytic oxidation on the surface.
Aluminum base plate is the main raw material for PS plate production, accounting for 80% of the total consumption. It is not only a support for the PS plate, but also has great effect on the performance of PS plate.
Offset printing is realized by the principle of water and ink balance, so the quality of grain structure has a great influence on the quality of the printed product. The state of grain layer is related to the quality of the aluminum plate and the electrolytic and oxidation processes.
Therefore, the production of the PS plate has high requirements for the aluminum base plate. The quality of the aluminum sheet has close relationship with the quality of the aluminum ingot and the rolling process.
The quality industrial pure aluminum sheet is a primary choice for PS plate. There are two roughening ways for base plate treatment. One is physical roughening, the other is duielectrolytic roughening.
At present, most PS plate manufacturers adopt the electrolytic graining process to form a uniform and dense grain layer on the surface of the aluminum plate. 1050 aluminum sheet is the popular aluminum sheet is the common choice for this treatment. As a big aluminium sheet manufacturer in China, Haomei offer you superior 1050 aluminum sheet.
