Zusammenfassung:	To improve printing accuracy.SOLUTION: A liquid jet device includes a liquid jet head 10 which has a jet surface F1 having a first nozzle array NLA for jetting first ink, and a second nozzle array NLB for jetting second ink, and can hold the liquid jet head 10 in a first posture in which the jet surface F1 inclines with respect to a horizontal plane F0. Dynamic surface tension of the second ink is higher than dynamic surface tension of the first ink. The first nozzle array NLA is positioned above the second nozzle array NLB in a gravity direction G1 in the first posture.SELECTED DRAWING: Figure 4 【課題】印刷精度の向上を図る。【解決手段】液体噴射装置は、第１インクを噴射する第１ノズル列ＮＬＡと、第２インクを噴射する第２ノズル列ＮＬＢとを含む噴射面Ｆ１を有する液体噴射ヘッド１０を備え、水平面Ｆ０に対して噴射面Ｆ１が傾斜する第１姿勢で液体噴射ヘッド１０を保持可能である。第２インクの動的表面張力は、第１インクの動的表面張力より大きい。第１姿勢において、第１ノズル列ＮＬＡは、重力方向Ｇ１に関し第２ノズル列ＮＬＢよりも上方に位置する。【選択図】図４
