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).
CTP plates of different thicknesses have different compressive strength, printing durability, stability and compatibility.
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.
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.
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 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.
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.
The CTCP plate produced by HONGCHANG Aluminum is renowned for its high resolution, superior quality, excellent compatibility, and cost-effectiveness.
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,
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.
