Current Situation of PS Aluminium Plate in Domestic

PS aluminium plate refers to the sensitive layer carrier of PS plate, which is aluminium thin sheet with thickness of 0.14 mm, 0.27 mm or others. PS aluminium plate refers to that a sensitive layer is coated on aluminium sheet, then printers print patterns on it. This is used for the printing for books, newspapers, etc. PS aluminium plate is adopted high quality alloy aluminium sheet (in generally, it is primary aluminium with a 99.5% aluminium content, such as 1050 aluminium alloy and 1060 aluminium alloy). Some grades are added letter A, which shows it must have high quality and has more strict requirements for impurities and properties. Besides, the common temper of this kind of plate is H18.

Printing has a high demand for PS aluminium plate, especially for high classic color printing. Thus, the quality of PS aluminium plate is the most important part.

Besides, no color difference or other problems should exit. Caustic washing procedure use liquid with low density, and short treatment time. If the surface has too much oil, then under this circumstance, the oil cannot be cleaned completely. Thus, in later processing, black dots or line will occur, finally, the PS plate will have a lot of problems.
