Product Overview

Description

 positive offset ps plate China

Feature

Unique Air Eduction Layer - Perfect Dot Reproduction
With tiny air eduction grain on the Baotu PS plate surface, the vacuuming time during exposure can be greatly decreased, as well as preventing image halation.

Unique Photosensitive Coating - High Sensitivity
Baotu'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. Baotu's unique photosensitive coating ensures Baotu 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. Baotu'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
Baotu'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.
