Liquid discharge apparatus and method for discharging liquid

摘要

A liquid discharge apparatus having heads (11) with liquid dischargers including nozzles (18) aligned in parallel in a row. Each liquid discharger has a main controlling unit for discharging ink droplets from the nozzles (18) of the liquid discharger, a secondary controlling unit for controlling the discharge of a droplet so that the droplet is discharged along at least one trajectory different from the trajectories of the droplets discharged from a liquid discharger controlled by the main controlling unit, and a secondary-control executing unit for individually setting whether or not the secondary controlling unit for each liquid discharger is operated. The liquid dischargers controlled by the secondary controlling unit discharge ink droplets along different trajectories compared to the ink droplets discharged by other liquid dischargers.
