Photosensitive offset printing, ctcp plate
Features
First Class Aluminum Substrate - Excellent Long Run Length
The first class aluminum base of Baotu's CTCP plate maintains an even surface, exact dimension and all kinds of physics and mechanical capabilities.
Compound Halftone Frame and Oxidation Layer - Exact Dot Reproduction
The multi-layer compound halftone frame and close-grained oxidation layer on the surface ensures exact dot-reproduction and excellent endurance.
Hydrophilic Managing Substrate - Excellent Ink-water Balance on Printing
Baotu UV-CTP plates adopt hydrophilic managed substrate to not only ensure the firm combination between sensitive layer and substrate but also improve the balance between water and ink so that it prevent from scum when machine idle and during printing.
Excellent Coating Component - High Sensitive Speed
Baotu UV-CTP plates adopt excellent coating component to keep the plate well-proportioned coated, with high sensitive speed, fine dot-reproduction and long run length. These make Baotu CTCP plate fit for top grade commercial printing and newspaper printing.
