UV-Ink Thermal CTP Plate

Double Photosensitive Layer - suitable for UV ink and general ink
Ronsein TPU UV ink thermal CTP plate is double layer thermal plate. Suitable for both UV ink and general ink.

High Resolution of Image Output
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.

Excellent Hydrophilicity - excellent ink-water balance performance
Hydrophilic treatment and post anodizing treatment provide excellent water retaining capability at the non-image area and prevent scumming.

Multi-grains Structure - Excellent Runlength and Ink-water Balance
The multi-grains structure of Ronsein CTP plate improves water retaining capability and keeps ink-water balance optimally.

Structure

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.
