To provide a liquid discharge device in which solid wettability is excellent, and which is capable of effectively suppressing image density unevenness.SOLUTION: A liquid discharge device includes: a carriage provided with a head for discharging liquid on a discharging object; a drive part for relatively moving the carriage and the discharging object; a measuring part for measuring a distance between the carriage and the discharging object; an imaging part for imaging the discharging object; and a setting part for setting discharging performance of the liquid from the head, on the basis of a measuring result of the measuring part, and a captured image obtained by imaging with the imaging part. The liquid is ink, and the ink contains water, an organic solvent, a color material, and plural polysiloxane compounds.SELECTED DRAWING: Figure 12 【課題】ベタ濡れ性が良好であり、画像濃度ムラを効果的に抑制することができる液体吐出装置の提供。【解決手段】被吐出物に対して液体を吐出するヘッドを搭載したキャリッジと、前記キャリッジと、前記被吐出物とを相対的に移動させる駆動部と、前記キャリッジと、前記被吐出物との距離を計測する計測部と、前記被吐出物を撮像する撮像部と、前記計測部の計測結果と、前記撮像部による撮像で得られた撮像画像とに基づいて、前記ヘッドからの前記液体の吐出性能を設定する設定部と、を備え、前記液体がインクであり、前記インクが水、有機溶剤、色材、及び複数のポリシロキサン化合物を含有する液体吐出装置である。【選択図】図１２
