0.15mm 0.30mm Double-Layer Thermal CTP Plates for Sale

In the modern printing industry, CTP (Computer to Plate) technology has become
the mainstream plate-making method. Among them, Double-Layer Thermal CTP
Plates are widely used in commercial printing, packaging printing, and
publication printing due to their high stability, excellent imaging quality,
and good printing durability.
To meet different printing requirements, 0.15mm and 0.30mm double-layer thermal
CTP plates have become preferred products for many printing plants and traders
thanks to their structural advantages and stable performance.
0.15mm Thickness: Mainly used for small and medium-sized offset printing
machines, form printing, and label printing. Its excellent flexibility makes
plate mounting easier and provides better fitting performance.
0.30mm Thickness: Preferred for commercial web presses, large poster printing,
and packaging carton printing. The high-strength aluminum alloy substrate
ensures dimensional stability during large-format printing.

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.

FAQ
Q1: What is the difference between double-layer CTP plates and single-layer
plates?
A: Double-layer plates add a protective layer on the photosensitive layer,
improving durability and anti-contamination performance. They are suitable for
high-intensity printing applications.
Q2: How to choose between 0.15mm and 0.30mm plates?
A: 0.15mm is suitable for film printing and lightweight applications; 0.30mm
is suitable for heavy-duty printing requiring long service life and high wear
resistance.
Q3: What is the storage period of the plates?
A: Under sealed packaging, the plates can be stored for 24 months. Please keep
them in a dry and ventilated place.
