Aluminum substrate offset printing ps plate

The aluminum substrate offset printing PS plate is a new type of printing material that has become an essential component in the offset printing industry due to its exceptional printing performance, long-lasting durability, and environmental benefits.

The PS plate combines the sturdiness of the aluminum substrate with the high precision of the photopolymer plate, offering clearer and more detailed image reproduction during printing. It significantly improves production efficiency while reducing material waste. This material is suitable for mass production and ensures consistent print quality for every batch, widely used in commercial printing, packaging printing, book publishing, and other fields.

Material and Structural Characteristics

Aluminum Substrate Selection

The base material is typically made from 1-series pure aluminum alloys such as 1050, 1060, and 1070. The aluminum plate undergoes electrolytic roughening to create a uniform matte texture that enhances the adhesion of the coating and increases hydrophilicity. The thickness of the aluminum plate generally ranges from 0.13mm to 0.40mm, with an H18 hard temper treatment to ensure mechanical strength and dimensional stability.

The anodized layer (Al₂O₃ film) significantly enhances the aluminum substrate's wear resistance and chemical stability while acting as a hydrophilic layer to reduce the risk of contamination during printing.

Functional Layer Design

The photosensitive layer is divided into photopolymer type (negative plate) and photo-decomposable type (positive plate), which selectively hardens the image area through ultraviolet exposure.

The rough surface gas layer optimizes the film’s adhesion, reduces vacuum time, and minimizes halo interference during the exposure process.
