Pls see below feature for Conventional Positive Plates:

Aluminum plate base, exposed electrolytic layer of sand, oxide layer, hydrophilic layer, photosensitive resin layer and coarse surface translation gas layer etc.

Each layer has its own specific treatment technology, which has enhanced the resolution, printing stability, chemical corrosion resistance, ink balance etc. All these make our products adapt well to the press printing and high-level color printing.
