High photosensitive speed CTP plates are advanced printing materials used in the printing industry that can directly transfer image information to printing plates through computers. Compared with traditional printing platemaking methods, CTP plates have higher efficiency and better image quality, and are particularly suitable for high-speed and high-precision printing needs.

Technical parameters of high photosensitive speed CTP plates:

- Photosensitive materials: high-performance polymers or aluminum-based materials

- Exposure method: direct laser exposure

- Resolution: optional 1200 dpi, 2400 dpi or higher

- Number of printing cycles: up to 50,000 times (depending on the specific application)

Types of high photosensitive speed CTP plates:

1. Photosensitive CTP plate

- Purple laser photopolymerization plate:

The photosensitive wavelength is 410nm and the sensitivity is 80-100μJ/cm². It uses multi-layer coating technology, scans and images through purple lasers, and can be printed after preheating and development. The resolution supports 200lpi (2%-98% dots), and the print life reaches 150,000 prints (300,000 prints after baking).

- Silver salt diffusion plate:

Uses silver halide coating to generate metallic silver images after exposure, with extremely fast photosensitivity and dot reduction ability of 1%-99%. Suitable for multi-wavelength lasers (especially violet lasers), but the post-processing process is more complicated.

- Ultra-high sensitivity non-silver photosensitive resin plate:

By increasing the resin sensitivity (more than 10,000 times higher than traditional plates), it supports 488nm argon ion laser exposure, and the platemaking speed can be shortened to 5 minutes (four-opening layout), and the development uses a dilute alkali aqueous solution.

2. Thermal CTP plate

The photosensitive wavelength is concentrated at 830nm, relying on infrared laser thermal energy imaging.

- Low energy exposure design: For example, the FIT plate only requires 120mJ/cm² energy, and the platemaking equipment can increase the scanning speed, which is compatible with newspapers and commercial printing.

- No preheating treatment: The thermal CTP plate can achieve high printability without preheating and supports UV ink printing.

Features of high photosensitive speed CTP plates:

- High photosensitivity speed:

The printing plate uses advanced photosensitive materials and has extremely fast photosensitivity speed. It can complete exposure in a short time and improve platemaking efficiency.

- Excellent image quality:

High-speed CTP plates can achieve finer image details and higher resolution, ensuring the clarity and color reproduction of the printed products.

- Environmentally friendly:

Many high-speed CTP plates use environmentally friendly materials, which reduces the impact on the environment and meets international environmental standards.

- Strong durability:

The product has excellent wear resistance and chemical resistance, can maintain stable performance during the printing process, and extend the service life of the plate.

- Good compatibility:

It is widely compatible with various printing machine models and can be seamlessly connected with the existing printing process, which is convenient for users to operate and use.

Application areas of high photosensitive speed CTP plate:

- Commercial printing: such as the production of printed materials such as books, magazines, posters, etc.

- Packaging printing: used for packaging printing of food, medicines and other commodities.

- Label printing: suitable for various types of label printing needs.

High photosensitive speed CTP plates are an important technological innovation in the modern printing industry. With its high efficiency, high quality and environmental protection characteristics, they meet the market demand for fast and high-quality printing.
