To provide ink capable of producing a printed matter that does not have a streak even when a distance between a surface of a medium to be recorded, for example, such as a corrugated cardboard and an inkjet head is long.SOLUTION: The present invention relates ink that is used in an inkjet recording method in which a distance from a surface (x) having an ink discharge port of an inkjet head to a position (y) where a perpendicular of the surface (x) and a recording medium to be recorded intersect with each other is 2 mm or larger, in which the ink has viscosity in a range of 2 mPa/s or larger and smaller than 9 mPa/sec, and, surface tension in a range of 20 mN/m to 40 mN/m.SELECTED DRAWING: Figure 1 【課題】本発明が解決しようとする課題は、例えば段ボール等の被記録媒体の表面とインクジェットヘッドとの距離が長い場合であっても、スジを有さない印刷物を製造できるインクを提供することである。【解決手段】本発明は、インクジェットヘッドのインク吐出口を有する面（ｘ）から、前記面（ｘ）の垂線と被記録媒体とが交わる位置（ｙ）までの距離が２ｍｍ以上であるインクジェット記録方式で使用するインクであって、前記インクが、粘度２ｍＰａ・ｓ以上９ｍＰａ・ｓ未満の範囲で、かつ、表面張力２０ｍＮ／ｍ〜４０ｍＮ／ｍの範囲であることを特徴とするインクに関するものである。【選択図】図１
