Colored aluminum article producing method, coloring method, and liquid ejection apparatus

Abstract

This invention is to appropriately color aluminum materials. A method for producing a colored aluminum article by coloring an aluminum material includes: a mask forming step S104 of forming a defined region coating mask that covers a pre-defined region of the aluminum material; a coloring step S106 of coloring the aluminum material with a dye in a region not covered by the defined region coating mask; and a mask detaching step S108 of detaching the defined region coating mask from the aluminum material after the coloring step S106. In the mask forming step S104, a mask forming liquid as a liquid for forming the defined region coating mask is ejected onto the aluminum material with a liquid ejection head that ejects liquid using an inkjet system.
