PS/CTP Plates for Newspaper Printing
The stability and reliability of thermal CTP technology used in newspaper plate production allows you to achieve excellent printing quality and consistent, colorful images to attract readers and advertisers.
PS/CTP is a process of rolling aluminum alloy blanks into thin plates of a certain thickness through hot and cold rolling processes. The surface of the plate is treated with a specific process and coated with a layer of photosensitive resin. After drying, it is made into printing plates for various purposes. Commonly used aluminum alloys include 1050A aluminum plate, 1060 aluminum plate, 1050 aluminum plate, etc. The state is mainly H18, and the thickness range is 0.1-0.4mm.

Advantages of 1050/1060 aluminum plate for newspaper printing PS/CTP substrate:
1. Low density
2. High strength
3. Moderate wear resistance
4. Good forming
5. Good hydrophilicity
6. High stability
7. Good surface treatment
8. Corrosion resistance
Application of 1 series aluminum substrate:
Good text and image presentation is closely related to high-quality PS/CTP substrate. CTP substrate has very strict requirements on the quality of the plate surface and plate shape. 1 series aluminum plate has the advantages of high printing quality, strong printing durability, environmental friendliness, cleanliness, and reasonable cost, making it an indisputable high-quality PS/CTP plate substrate. It is widely used in offset printing plates such as positive PS plates, thermal CTP plates, photosensitive CTP plates, and UV-CTP plates.
