Positive Thermal CTP Plate

Extraordinary Plate Developing Tolerance - User Friendly and Dealer Friendly
Ronsein thermal CTP plate has wide plate developing tolerance. So it is suitable for most developer and the different concentration. So it is very good for the user and dealer to do the plate testing or plate using.

High Resolution
Ronsein's unique ingredients, together with the optimally distributed formula weight of binding polymers, in the coating of KTP offer fine dots with sharp edges and reproduce images with rich tone. The aluminum matrix of compound grain molybdenum structure technology ensures 1-99% microdot reproduction.

Good Quality of Printing Effect - Excellent Hydrophilicity
Hydrophilic treatment and post anodizing treatment provide excellent water retaining capability at the non-image area and prevent scumming.

Long Run Length - Multi-grains Structure
The multi-grains structure of Ronsein CTP plate improves water retaining capability and keeps ink-water balance optimally.

Working Principle

Marco-molecules are formed by cross-linked micro-molecules during the oven drying procedure of Ronsein CTP plate production.

(A) Thermal sensitive coating with IR-Absorber;

(B) Hydrophilic layer formed by sealing treatment;

(C) Electrochemically grained and anodized aluminum.

Infrared Laser exposures the non-image area. The IR-Absorber in the thermal sensitive coating converts light to heat and breaks the cross-linked structure.

The deformation of macro-molecules at the non-image area makes the coating alkaline soluble (Developer)

Image area remains insoluble to the developer.
