A thermal CTP plate is an aluminum-based printing plate coated with a thermally sensitive imaging layer. It is imaged by an 830 nm thermal laser CTP setter without the use of film, significantly improving prepress efficiency.
High sensitivity positive thermal CTP plates with excellent dot reproduction, stable imaging performance, and wide exposure latitude.Suitable for commercial and packaging offset printing.
In the field of newspaper printing, offset printing technology has become mainstream due to its fast speed, stable printing quality and adaptability to large-scale printing.
Thermal CTP plates use an infrared thermal laser around 830nm to create images directly on aluminum-coated plates, eliminating the need for traditional film transfer processes.
The CTCP plate produced by HONGCHANG Aluminum is renowned for its high resolution, superior quality, excellent compatibility, and cost-effectiveness.
CTP plates primarily use aluminum plates, which not only improves printing efficiency but also reduces plate-making costs.
A PS plate (Pre-sensitized Plate) is a pre-coated photosensitive plate usually composed of an aluminum substrate and a photosensitive coating.
0.3mm thick CTP plates are especially suitable for medium to large-sized printing equipment and scenarios with high requirements for printing accuracy and durability.
PS plates are offset printing plates made of aluminum plates (1050/1060/1070) as the base material and pre-coated with a photosensitive layer. They are widely used in various printing processes.
The core advantages of 830 nm thermal CTP plates lie in their operational stability and the convenience of working in a brightly lit environment.
The main raw material for CTP plates is the printing plate material, which is typically made from aluminum base plates (also called aluminum plates) that are treated with a coating to accept image transfer.

CTP plates of different thicknesses have different compressive strength, printing durability, stability and compatibility.
Aluminum coils for CTP/PS base plates are mostly made of high-purity aluminum alloys, such as 1050, 1060, 1100, etc. The aluminum content of these alloys is ≥99.50%, ≥99.60% and ≥99.00%, respectively. They have the advantages of high purity, low density,
CTCP (Computer to Conventional Plate) printing plate refers to the use of traditional PS plates with direct digital imaging, forming a new generation of UV-CTP plates.
CTP plates are mainly divided into five categories: thermal plates, violet laser plates, silver salt plates, UV-CTP plates, and the emerging free-processing plates. They are widely used in printing newspapers, magazines, etc.
1-Series photopolymer plate aluminum substrates are made from 1050, 1050A, 1060, and 1070 aluminum sheets as the supporting material for photopolymer plates (such as PS plates and CTP plates).
PS plate aluminum plate base usually uses high-purity aluminum alloy, which has good corrosion resistance and thermal conductivity. Commonly used aluminum alloys include 1050, 1060 and other series.
