Double-coated CTCP version
High Sensitivity and Excellent Printing Stability
Double-coated CTCP version
CTCP Plate, Double-coated CTCP Plate, UV CTP Plate, Positive-working Plate
The Double-coated CTCP Plate is a premium positive-working plate designed for Conventional (UV) Computer-to-Plate systems, also known as CTCP.
Featuring a dual-layer coating, this plate delivers higher resolution, superior stability, and outstanding resistance to UV ink and press chemicals.
Its durable aluminum substrate ensures long run-length and consistent dot reproduction, making it an ideal choice for commercial, newspaper, and packaging printers using UV or visible-light exposure systems.
The double-coated design enhances sensitivity, sharpness, and plate life, offering a cost-effective and reliable alternative to traditional analog plates.

Frequently Asked Questions
What is the main difference between CTCP and CTP plates?
CTCP plates are imaged using UV or visible light (350–450 nm), while CTP plates use thermal (830 nm) or violet (405 nm) lasers. CTCP systems are generally more cost-effective and easier to maintain.
Why use a double-coated CTCP plate instead of a single-coated one?
The double coating provides stronger resistance to UV exposure, better imaging sharpness, and longer press life—ideal for demanding print environments.
Can the plate be baked for extended runs?
Yes, baking can extend the plate life from 200,000 to 400,000 impressions, especially for UV ink or long packaging print runs.
Which developers are compatible with this plate?
Use standard positive-type CTCP developers; no special formulation is required. Always follow the recommended developing time and temperature for best results.
