CTP aluminum coil

CTP aluminum coil is one of the important raw materials used to make plates in Computer-to-Plate (CTP) technology.
1. Definition and characteristics
Definition: CTP aluminum coil refers to aluminum coil used in CTP plate production, and its quality directly affects the production of CTP plates and the quality of plates.

Features:
High surface quality: The surface of CTP aluminum coil needs to be clean and flat, without cracks, folds and other defects to ensure the apparent quality and printing effect of the plate.
Excellent physical properties: CTP aluminum coil has high hardness and strength, can withstand high-intensity printing force, and ensure the stability and consistency of printing quality.
2. Material and specifications
Material: CTP aluminum coil usually uses 1 series aluminum alloy, such as 1050, 1060, etc. These alloys have the advantages of low density, high strength, easy forming, high stability, and good surface treatment.
Specifications: The thickness of CTP aluminum coil is usually between 0.13-0.40mm, the width is 650-1420mm, and the length can be customized according to user requirements. Among them, the thickness of the aluminum base used for CTP plate production is generally 0.280mm or 0.275mm.
III. Application fields
CTP aluminum coil is widely used in various printing fields, such as book printing, packaging printing, commercial printing, etc. It is an important raw material for making positive PS plates, thermal CTP plates, photosensitive CTP plates, UV-CTP plates and other offset printing plates.

With the steady growth of downstream demand in my country, the market scale of CTP plate industry continues to expand. The upstream of CTP plate industry chain is mainly aluminum coils, photosensitive adhesives, etc. The production cost of the aluminum processing industry and the changes in the price of non-ferrous metals directly affect the production cost of plates.
