METHOD FOR TREATING SURFACE OF ALUMINUM-MADE MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a method for treating the surface of an aluminum-made material capable of easily performing a desired coloring on the entire surface area of the material while easily expressing an image of multicolor arrangement on the surface of the aluminum-made material. SOLUTION: The entire surface of the aluminum-made material can be expressed in a desired image and a desired color by performing an alumetizing step for performing alumite treatment on the surface of the aluminum-made material, a printing step for printing a predetermined image with an ink by an ink jet printer, a coloring step for dipping the raw material applied with the printing step into a dye to perform coloring on the surface of a portion other than the image printed by the printing step, and a sealing step for sealing openings of micropores in the material relative to the material color-processed with the coloring step.
