PROBLEM TO BE SOLVED: To control liquid discharge in light of a difference among a plurality of nozzles based on different timing from discharge to irradiation of an ultraviolet ray when discharging a liquid hardened by being irradiated with the ultraviolet ray from the nozzles.SOLUTION: A liquid having a property of being hardened when being irradiated with ultraviolet rays is discharged to a discharge target medium from a plurality of nozzles of a discharge head, and the discharge target medium is irradiated with the ultraviolet rays and hardened. At this time, the liquid is discharged from a part of nozzles among the nozzles in a different manner from a manner in which the liquid is discharged from the other nozzles different in timing since the liquid is discharged until the discharge target medium is irradiated with the ultraviolet rays. |
