Abstract (en)

A liquid discharge apparatus includes a liquid discharge surface (12) and a control unit (500). The liquid discharge surface (12) has a plurality of liquid discharge ports (11). The control unit (500) generates a drive waveform and controls discharge of liquid from the plurality of liquid discharge ports based on the drive waveform. The control unit (500) includes a plurality of droplet-count distribution tables (507a) in which information on a number of times of droplets to be discharged from each one of the plurality of liquid discharge ports is set. The control unit (500) forms the drive waveform by using a droplet-count distribution table selected from the plurality of droplet-count distribution tables based on information on a use environment of the plurality of liquid discharge ports acquired before starting a discharge operation of the liquid.
