offset printing presensitized plate

Specifications

We professionally offering PS plate with below characteristics:

1 Photosensitive Coating

Consisted by imported photographic emulsion and resin, the coating layer of the plate have outstanding alkaline resistance, superior stability, high sensitive and increased adjusting flexibility as well as better resolving power.

2 Vacuum ventilating layer

With tiny ventilating grain layer on the surface, the vacuuming time during exposure can be greatly decreased, as well as preventing the proportion of tiny dots from exposuring to vague.

3. Water Receptive Layer

Excellent water reception capability speeds up the ink-water balance procedure and helps to reduce water absorption during printing process. Superior water retaining capability do effectively prevents non-image areas of the plate from scumming and avoids paper from distortion. Consequently, the printing quality improved

4. Multi Grain Layers

Multi grain layers polish up water receptive property of the non-image areas on the plate. It increases the ink /water adjusting flexibility, make sure the developing performance of the tiny dots. It also strengthens the dots’ adsoption power to the coating layer, which can consequently extend the run-length of the plate.

5. Anodic-Oxidized Layer

A durable and strong oxidized surface formed after the anodic oxidation process on the aluminium material, which can help to prolong the run-length. This layer can also resists the corrosive effect done by the correction fluid.
