▎ 摘　　要

NOVELTY - A coated metal alloy substrate is produced by scanning metal alloy substrate to determine three-dimensional (3D) surface profile of at least a portion of metal alloy substrate; and printing greater than or equal to 1 coating layer on at least a portion of metal alloy substrate, where printing is adjusted according to the 3D surface profile of the metal alloy substrate. USE - Production of coated metal alloy substrate for electronic device (claimed). ADVANTAGE - The coated metal alloy substrate resulting from the process may have good esthetic properties, glossy surface finish, and good corrosion resistance with a relatively thin overall coating layer, which is lightweight Furthermore, the process may avoid polishing treatments, resulting in a more efficient process, preventing damage to the metal alloy substrate surface, and increasing corrosion resistance. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) coated metal alloy substrate comprising metal alloy substrate and greater than or equal to 1 printed coating layer on at least a portion of the metal alloy substrate, where greater than or equal to 1 printed coating layer printed on the metal alloy substrate is based on a 3D surface profile of the metal alloy substrate; and (2) electronic device comprising housing which comprises the coated metal alloy substrate.
