Abstract:
A liquid discharging apparatus includes: a liquid discharge head including plural nozzle rows each arrayed with plural nozzles and discharging liquid droplets onto a workpiece by a multi-pass method using n recording passes (n is an integer of 3 or more); and a head drive section that controls driving of n nozzle groups corresponding to the n recording passes in each of the nozzle rows with a discharge duty upper limit specific to each nozzle group, and for a pair of nozzle groups adjacent across the nozzle rows, when controlling driving of one of the nozzle groups with a discharge duty upper limit being the maximum discharge duty upper limit of one nozzle row containing the one nozzle group, controls driving of the other nozzle group with a discharge duty upper limit that is not the maximum discharge duty upper limit of another nozzle row containing the other nozzle group.
