What Is PS Plate
PS plate or offset printing is a kind of conventional plates for use with film based production processes, manufactured for superior performance. We also have CTP plates for you.
Haomei PS plate, with durable and strong oxidized surface, excels other manufacturer in terms of largely increased printing capacity, corrosion resistance and run length.
Advantages of Positive PS Plate
Excellent resolving ability. Our photosensitive coating is made up of top photographic emulsion and resin, which is of great alkaline resistance, stability and high sensitivity.
Superior pressrun ability. Anodic-oxidation layer is of the superior durability, good chemical resistance for long runs and great printing reliability.
Sustainable Ink-water Equilibrium. We use diazo phtosensitive resin matched with aluminum oxide film, speeding up the ink-water equilibrium procedure.
Our PS plate is compatible with most positive plate developers and processors on the market.
Multiple layer grain structure not only ensures the printing quality, but also ensures its long-term stability.
