Ⅰ: What is aluminum sheet for ps printing plate
PS aluminum plate (advertising aluminum plate, also known as printed zinc plate, newspaper plate): that is, the aluminum plate with a printed pattern thickness of 0.25 or 0.3 mm on the back. It is a lithographic aluminum plate pre-coated with a photosensitive resin layer on the aluminum plate substrate. The commonly used PS aluminum substrates are 1050, 1060 and 1070 alloys, and the aluminum content is more than 99%.
