Blue thermal CTP printing plate

Blue thermal CTP printing plate is the core material in modern printing technology and is widely used in various types of high-precision and large-scale printing production. This printing plate combines the advantages of thermal imaging technology and digital platemaking. With its high resolution, excellent printing resistance and environmental protection characteristics, it plays an important role in commercial printing, packaging printing and publishing printing.

The material of the blue thermal CTP printing plate is mainly composed of the plate base and the photosensitive layer:

The aluminum plate base is the basic material of the blue thermal CTP printing plate. It carries the photosensitive layer and determines the overall performance and durability of the printing plate. Common plate base materials are mainly aluminum plates, especially 1 series pure aluminum plates, and the commonly used alloy numbers are 1050, 1060, 1070, 1100, etc. Aluminum plates have the characteristics of low density, high strength, good ductility, and strong corrosion resistance, which are very suitable as the plate base material of the printing plate.

During the manufacturing process, the aluminum plate will undergo a series of treatment processes, such as grain treatment, anodizing, etc., to form a uniform and fine grain structure and a dense oxide film. These treatment processes can enhance the bonding strength between the base and the photosensitive layer, and improve the printing resistance and dot reduction performance of the printing plate.

The photosensitive layer is the key part of the blue thermal CTP printing plate, which determines the photosensitivity and printing quality of the printing plate. The photosensitive layer is usually composed of thermal resin, sensitizing dye, infrared absorbing dye, etc.

Features of thermal CTP plate:

1. High-precision imaging: Thermal CTP technology provides high resolution, which is suitable for high-precision printing needs of complex graphics.

2. Significant visual effect: The blue surface improves the visual contrast of the image inspection after exposure, which is convenient for quick judgment of exposure and development quality.

3. Wide adaptability: The blue thermal CTP printing plate is suitable for a variety of printing machine models, including offset printing machines and rotary printing machines, and is used in packaging, publishing and other printing fields.

4. Strong durability: The aluminum substrate is anodized and surface treated, can withstand the mechanical pressure in high-speed printing, and has good chemical corrosion resistance.

5. Environmental protection: Compared with traditional PS plates, thermal CTP plates reduce the use of chemicals, have a high printing durability, reduce waste generation, and have low energy consumption in the platemaking process.

Application areas:

Blue thermal CTP printing plates are widely used in packaging printing, commercial printing and other fields. In packaging printing, blue thermal CTP printing plates can produce high-precision and high-quality prints to meet the packaging industry's requirements for printing quality.
