Abstract:
1. A liquid droplet discharge apparatus comprising: a liquid droplet discharge head comprising a plurality of nozzles arranged in an array along a first direction; and a control unit configured to control the liquid droplet discharge head to discharge liquid droplets from the plurality of nozzles toward a recording medium while moving the recording medium in a second direction orthogonal to the first direction or while moving the liquid droplet discharge head in the second direction, so as to form an image on the recording medium, wherein the plurality of nozzles comprises: wherein the control unit is configured to control the liquid droplet discharge head to form a dot array by the liquid droplets discharged from the plurality of main nozzles and the plurality of sub nozzles, the control unit controlling a timing of the discharge of the liquid droplets of the plurality of main nozzles and a timing of the discharge of the liquid droplets of the plurality of sub nozzles to be different from each other, wherein the dots in the dot array formed from the plurality of sub nozzles deviate in the second direction from the dots in the dot array formed from the plurality of main nozzles.
