Cost-efficient CTP
Delivers computer-to-plate quality on existing conventional UV plate-setters, avoiding costly new equipment.
Even surface, exact dimensions
First-class aluminum substrate is evenly grained and dimensionally precise for predictable registration.
High resolution
Fine grains keep small highlight and shadow dots stable across the run for clean tone reproduction.
Good press stability
Maintains ink-water balance and dot shape through long runs, reducing makeready and waste.
Durable anodic-oxidized layer
The durable oxidized surface formed by anodizing the aluminum base resists corrosion and retouching medium, markedly extending plate run length.

FAQ
What is CTCP and how is it different from CTP?
CTCP (Computer-to-Conventional-Plate) images conventional UV plates with a UV (405 nm) platesetter instead of a thermal (830 nm) one, so you reuse existing plate types and avoid thermal hardware cost.
What platesetters run Ronsein CTCP-P plates?
CTCP-P plates work with UV 405 nm platesetters such as BasysPrint, Luscher UV, and most violet/UV CTCP engines.
What are the processing conditions?
Develop with a compatible CTCP/UV plate developer at the bulletin-recommended temperature and time; store at 22–24°C and avoid prolonged UV ambient light.
