The present invention relates to a roller for printing materials on metal, used for printing a base color on a metal sheet. The roller comprises: a core (10) serving as a rotary shaft; a cylindrical roller body (20) coupled to the core; and a printing plate (30) detachably attached to an outer surface of the roller body (20). The roller of the present invention enables the replacement of the printing plate alone instead of replacing the entire body of the roller, thereby enabling the easy replacement of the roller and shortening the time taken for replacing the roller. |
