As a core consumable in the printing industry, the product is widely used in book publications, commercial promotional products, newspapers and periodicals, and packaging and printing products.

[0003] The PS plate uses the principle of offset printing that oil and water are incompatible. After exposure and development, two regions are formed: 1: graphic area: the retained part of the photosensitive layer, which is oil-loving and water-repellent, and adheres to ink.

[0004] 2: non-graphic area: the photosensitive layer is removed, exposing the hydrophilic aluminum base, and adhering to the dampening solution.

[0005] The aluminum base coated with a photosensitive material is cut into a fixed length and width according to the order, and a separator paper is applied to separate the aluminum plates. The pages are marked with a page bar to indicate the number of sheets per package, and the stack is formed at the receiving position.
