Abstract:
1. A printing method, comprising: an ink ejection process, in which an ultraviolet curing type metallic ink including a monomer or an oligomer polymerized by irradiation of ultraviolet rays as a binder and scale shape or flat shape metal particles is ejected on a recording medium, and the recording medium is swelled by the metallic ink, soaked with the metallic ink, or dissolved by the metallic ink; a leveling process, in which the metallic ink on the recording medium is leveled, and the metal particles are aligned in a plane direction parallel to a surface of the recording medium in a state that the metal particles are interposed between the recording medium and a surface of an ink layer; a temporary curing process, in which ultraviolet rays are irradiated to the metallic ink on the recording medium and the leveling process is continuously performed, and a penetrated amount of the metallic ink into the recording medium is reduced; and a main curing process, in which ultraviolet rays are irradiated to the metallic ink on the recording medium for curing after the temporary curing process, wherein the metallic ink is ejected by an inkjet printer so that landed ink droplets are flattened and unified with adjacent ink droplets before the main curing process is performed.
