Zusammenfassung:To make color unevenness hardly occur in a sprayed portion in a printing object when a liquid chemical is sprayed by a spray device.SOLUTION: A printer 10 comprises: a support base 12 which supports a printing object 5; a print head 20 which discharges ink toward the printing object 5; a liquid chemical tank 32 which stores a liquid chemical to be sprayed to the printing object 5; a spray device 31 which is connected to the liquid chemical tank 32, atomizes the liquid chemical with the compressed air and sprays the liquid chemical toward the printing object 5 supported on the support base 12; a spray carriage 40 which is provided with the liquid chemical tank 32 and the spray device 31; and a control device 120. The control device 120 includes an agitation control unit 123 which causes the spray carriage 40 to reciprocate in a main-scanning direction Y to agitate the liquid chemical stored in the liquid chemical tank 32 without causing the spray device 31 to spray the liquid chemical in a non-printing time in which printing is not performed on the printing object 5.SELECTED DRAWING: Figure 9 【課題】スプレー装置によって液剤を噴霧したときに、被印刷物における噴霧された部分に色ムラが発生し難い。【解決手段】プリンタ10は、被印刷物5を支持する支持台12と、被印刷物5に向かってインクを吐出するプリントヘッド20と、被印刷物5に噴霧される液剤を貯留する液剤タンク32と、液剤タンク32に接続され、圧縮空気によって液剤を微粒化して、支持台12に支持された被印刷物5に向かって液剤を噴霧するスプレー装置31と、液剤タンク32およびスプレー装置31が設けられたスプレーキャリッジ40と、制御装置120とを備える。制御装置120は、被印刷物5に印刷しない非印刷時、スプレー装置31から液剤を噴霧させずに、スプレーキャリッジ40を主走査方向Yに往復移動させて、液剤タンク32に貯留された液剤を攪拌させる攪拌制御部123を備えている。【選択図】図9
