PROBLEM TO BE SOLVED: To provide an instrument dial with highly decorative appearance that looks differently colored depending on the viewing angle.SOLUTION: A plurality of ink layers 11, 12 and 13 constituting each pixel 10A on an instrument design surface 3 printed on a substrate 2 are formed by iteratively performing: an ink application step for having a droplet of an ultraviolet-curable ink land on the substrate 2 using a print head of a UV-curable inkjet printer; and an ink curing step for irradiating the ink droplet with ultraviolet rays to form a cured ink layer before the ink droplet that has landed on the substrate 2 is flattened by gravity. Colors of the laminated ink layers 11, 12 and 13 of each pixel 10A become visible when the design surface 3 is viewed from a direction other than the normal direction.

    【課題】視る角度によって彩色が変化して見映えが変わり、装飾性の高い外観を提供することのできる計器用文字板を提供すること。【解決手段】基板2上に印刷された計器用の意匠面3の画素10Aを構成する複数のインク層11,12,13は、紫外線硬化型インクのインク滴をUV硬化型インクジェットプリンタの印刷ヘッドで基板2に着弾させるインク塗布工程と、基板2に着弾したインク滴が自重で平坦化する前にインク滴に紫外線を照射して硬化したインク層とするインク硬化工程と、を同一箇所で繰り返すことで形成され、意匠面3を正面からずれた位置から視ると、各画素10Aの積層している各インク層11,12,13の発色を視認することができる計器用文字板。【選択図】図6
