<P>PROBLEM TO BE SOLVED: To provide a printing method for an aluminum product, capable of improving the efficiency of manufacturing work by eliminating some manufacturing steps. <P>SOLUTION: The printing method for an aluminum product comprises: an anodic oxide film-forming step S1 of forming an anodic oxide film having micropores on a surface of an aluminum body; a printing step S3 of conducting printing by a printer using a UV ink on the surface on which the anodic oxide film is formed; and a sealing treatment step S5 of sealing the micropores on the anodic oxide film after the printing. After forming the anodic oxide film, printing is directly conducted using the printer and the UV ink, thereby simplifying the manufacturing steps. A plurality of micropores on the anodic oxide film enables integration of the UV ink to the surface of the body. The printing efficiency can be further improved by using an inkjet printer as the printer. <P>COPYRIGHT: (C)2013,JPO&INPIT |
