PROBLEM TO BE SOLVED: To provide an inkjet printing device that can reduce ink mist.SOLUTION: An inkjet printing device 1 comprises: a conveying portion 2 that conveys a printing medium; a plurality of inkjet heads that perform discharging of ink, for each line of an image, to the printing medium to be conveyed by the conveying portion 2; a head cooling portion 4 that cools the plurality of inkjet heads by generating cooling air; and a control portion 9 that controls the inkjet head so that precursor driving which is driving not strong enough to discharge ink is performed onto at least part of the lines to which ink is not discharged. The control portion 9 determines precursor ratios that are ratios of lines onto which the precursor driving is performed among the lines to which the ink is not discharged for each inkjet head, according to a position of each inkjet head.SELECTED DRAWING: Figure 1 |
