Product Features of Double-Layer Thermal CTP Plates
Excellent Run Length
The double-layer coating gives the printing plate extremely high durability. Under normal printing conditions, it offers a high run length and maintains consistent print quality even during long-run commercial printing.
Excellent Dot Reproduction
The plate has a wide development latitude and can accurately reproduce fine dots from 1% to 99%. Whether for very fine text or large-area high-quality flat screens, it maintains sharp edges without dot loss or plate blinding.
Fast Sensitivity and High Production Efficiency
Optimized for 830nm thermal plate setters, the high-sensitivity formula shortens exposure time per plate. It performs excellently on high-speed plate-making machines and significantly improves daily output in the plate-making workshop.
High Resolution and Vivid Colors
With multi-layer graining technology and double-layer coating technology, the plate meets high-end printing quality requirements and ensures full, vivid color performance.
Compatible with UV Ink
Its strong coating structure provides excellent chemical and scratch resistance. It can be compatible with UV ink without baking, making it especially suitable for high-end packaging printing.
No Preheating Required for Some Models
Many double-layer thermal plates are positive-working plates and do not require preheating, simplifying the workflow.
Long Shelf Life
High-quality double-layer thermal plates usually have a long shelf life, such as more than 18 months.
Wide Application Fields
With stable chemical performance and physical specifications, this series of CTP plates is widely used in:
Book and Magazine Printing:Ensures clear text and stable performance during long-run printing.
Packaging Color Boxes:Performs steadily on heavy paper and complex image processing.
UV Printing:Specially reinforced double-layer coating provides natural resistance to UV ink.
Commercial Quick Printing:The 0.15mm specification can be quickly mounted on the machine, meeting the needs of short-run quick printing.
