830nm Thermal CTP Plate 0.15mm for Offset Printing

Thanks to its excellent dot reproduction, safe daylight handling, and stable printing performance, thermal CTP technology has become the dominant solution in commercial and packaging printing.

The thermal CTP plates manufactured by Hongchang Aluminum are aluminum-based printing plates designed for prepress applications. Available thicknesses include 0.15mm, 0.20mm, 0.25mm, and 0.30mm. These plates adopt thermal imaging technology and are exposed by an 830nm infrared laser, requiring no chemical film processing, making them well suited for commercial printing requirements.

Core Structure and Material Advantages of Thermal CTP Plates

During manufacturing, we apply mature and well-controlled processes from aluminum substrate treatment to photosensitive coating:

High-Quality Aluminum Substrate
Made from 1050/1060 aluminum sheets, processed through precision electrochemical graining and anodizing. The surface features uniform pore structure and stable hydrophilicity, providing reliable adhesion for the photosensitive layer while improving press life and service durability.

High-Sensitivity Thermal Photosensitive Layer
Optimized specifically for the 830nm wavelength, the coating responds rapidly to laser energy, delivers sharp imaging, and ensures accurate dot reproduction, effectively minimizing the impact of exposure energy fluctuations on plate quality.

Standard 0.15mm Thickness Design
While ensuring sufficient rigidity and flatness, the 0.15mm thickness offers excellent bendability, reducing deformation risks during mounting and press operation. It is especially suitable for continuous, stable printing on medium- to high-speed offset presses.

Compared with traditional 0.20mm or 0.30mm plates, the 0.15mm thin base provides significantly improved bending performance, allowing faster and tighter attachment on high-speed cylinders and directly reducing makeready time.

Key Performance Characteristics of Thermal CTP Plates

1.Sharp Imaging and Excellent Dot Reproduction
Stable performance for fine text and high-line-screen dots, meeting high-quality commercial printing demands.

2.Wide Processing Latitude
Strong tolerance to variations in developing time, temperature, and chemistry, reducing operational risks during production.

3.Stable Press Life
Suitable for medium to long print runs, minimizing plate changes and improving overall press efficiency.

4.Excellent Registration and Paper Transport Stability
High plate flatness helps maintain consistent registration accuracy and enhances finished product consistency.

Offset Printing Applications

• Commercial Printing
  Ideal for magazines, books, brochures, and other high-quality print jobs, delivering sharp text and vivid images.

• Packaging Printing
  Used for food, cosmetics, and electronics packaging, ensuring bright, durable graphics and compliance with food-contact safety standards.

• Labels and Stickers
  Supports high-precision printing of barcodes, QR codes, and fine patterns for pharmaceutical, chemical, and electronics industries.

• Printing Plate Templates
  Suitable for producing various printing templates, including screen printing and silk-screen applications, providing high-precision image transfer.

Compatibility with Mainstream 830nm CTP Devices

As a manufacturer, we fully consider mainstream equipment configurations during product design. This CTP plate is highly compatible with a wide range of 830nm thermal CTP plate setters. With a wide exposure parameter window, customers can easily integrate the plates into existing systems without equipment modification, significantly lowering the barrier to adoption.

Why Choose Our Thermal CTP Plates?
