High quality thermal CTP plates are superior in many ways. Below are some of the key features and criteria for determining the quality of a thermal CTP plate.

Characteristics of high quality thermal CTP plates:

- Excellent light-sensitive properties:

High-quality thermal CTP plate adopts advanced thermal imaging technology with low sensitivity to natural light, so it can be operated under bright room conditions, avoiding the tediousness of traditional plate making that requires a dark room environment.

With infrared laser exposure, it is capable of generating high-quality images with good dot reproducibility, high resolution, and sharp, clear edges.

- Stable plate making quality:

Thermal CTP plate making technology is one of the most mature and stable plate making technology.

The exposure of the plate can be extended to 6 months after the development, the quality of the plate will not have the slightest impact on the quality of the plate, to ensure the stability and reliability of the quality of plate making.

- Good printing suitability:

The dot reproduction range of thermal CTP plate can reach 1%~99%, which can meet various printing demands.

After baking the plate, the printing resistance of the plate can reach more than 1,000,000 prints, which is suitable for long printing, reducing the cost of plate change and repeated plate making.

- Environmental protection and energy saving:

High-quality thermal CTP plates do not require chemical development in the plate making process, which reduces the generation of chemical waste liquid and is non-polluting to the environment.

The plate making process is short, which improves the production efficiency and reduces the energy consumption.

How to judge the quality of thermal CTP plate:

- Observe the appearance:

The appearance of high-quality thermal CTP plate should be flat and smooth, without obvious scratches, stains and bubbles.

The coating of the plate should be uniform and thick, and the dot reproduction is clear.

- Test light-sensitive performance:

Use infrared laser for exposure test to observe the photosensitive speed and dot reproduction of the plate.

A good quality plate should be able to form a clear, even dot after exposure, with sharp edges and no blurring.

- Evaluate printability:

Evaluate the printability of the plate through actual printing tests.

Observe the ink transfer on the plate, as well as the color reproduction and clarity of the print.

- Know the manufacturer and brand:

Choose high-quality thermal CTP plates from well-known manufacturers and brands, as these manufacturers usually have advanced production technologies and strict quality control systems to ensure the quality and stability of the plates.

With these criteria and methods, you can evaluate the quality of thermal CTP plates more effectively and ensure that you choose a high-quality product that suits your needs.
