CTP sheet is a technology in the printing industry that can directly transfer electronic files to the printing machine for sheet making without the need for subsequent processing. In the production process of CTP sheets, aluminum sheet base is one of its important raw materials. CTP sheets have certain requirements on the flatness of the sheet base, material chemical composition, mechanical properties, thickness and width and other parameters.

The aluminum sheet base alloys used for CTP sheet production include 1110, 1050, 1060, 1070 aluminum sheets, etc. The CTP version aluminum substrate is made of 1050 aluminum sheet, 1060 aluminum sheet, and 1070 aluminum sheet alloy, with aluminum content of ≥99.50%, ≥99.60%, and ≥99.70% respectively. It has the advantages of low density, high strength, good formability, good hydrophilicity, high stability, and good surface treatment, making it an indisputable CTP sheet base material.
