High press runs Offset PS plates:

Specification of Positive PS Printing Plate
Photosensitive Coating:
Coated by imported photographic emulsion and resin, the plate provides outstanding alkaline resistance, superior stability, high sensitive, high resolution & wide latitude---- Positive PS Printing Plate.

Vacuum Ventilating Layer:
Decreased exposure time, and avoids the dots from exposure to vague--- Positive PS Printing Plate.

Hydrophilic Treatment:
Speedy ink-water balance and less water absorption. Superior water retaining capability prevents the non-image areas from scumming and avoids paper distorted----- Positive PS Printing Plate.

Multi Grain Layer:
Enhance water receptive property of the non-image areas, insure dotes reproduction, and, extend the run-length---Positive PS Printing Plate.

Anodic-Oxidized Layer:
After anodic oxidation process, the plate has longer run-length, and can better resists the corrosive effect of the correction fluid--- Positive PS Printing Plate.
