Positive PS Plate

Unique Air Eduction Layer - Perfect Dot Reproduction With tiny air eduction grain on the Ronsein PS plate surface, the vacuuming time during exposure can be greatly decreased, as well as preventing image halation. Unique Photosensitive Coating - High Sensitivity Ronsein's unique photosensitive coating consists of world’s first class photographic emulsion and resin, which offers outstanding alkaline resistance, superior stability, high sensitivity and increased adjusting flexibility. Ronsein's unique photosensitive coating ensures Ronsein PS plate of unmatched resolving ability. Excellent Hydrophilic Layer - Sustainable Ink-water Equilibrium Excellent water reception capability speeds up the ink-water equilibrium procedure and helps to reduce water absorption during printing process. Ronsein's superior water retaining capability do effectively prevents non-image areas of the plate from scum and avoids paper distortion. Outstanding Multi Grain Layer - Excellent Performance in Developing Ronsein's multi grain layer polishes up the hydrophilic substances of the non-image areas on the plate. This increases the ink-water adjusting flexibility and enhances the developing performance of the tiny dots. This also strengthens the dots’ ability to adsorb the coating layer, which consequently extends the run length of the plate. Durable Anodic-oxidized Layer - Extraordinary Run Length The durable and strong oxidized surface formed after the anodic oxidation process on the aluminum material prolongs the run-length of Ronsein plate. Anodic-oxidized layer also resists the corrosion of the retouching medium.
