Abstract
A droplet discharge device is configured to control the drive corresponding to a prescribed set of the nozzles selected to discharge droplets during a main scan when the droplets are arranged in the first partition regions, based on a pre-measured distribution of a droplet discharge amount of each of the prescribed set of the nozzles so that the droplet discharge amount approximates a predetermined optimal amount, and to control the drive waveforms corresponding to the nozzles included in a plurality of potential combinations of the nozzles selected to discharge droplets during a main scan when the droplets are arranged in the second partition regions, based on a pre-measured distribution of an average droplet discharge amount calculated from an amount of droplets discharged from the each of the nozzles in all the potential combinations so that the droplet discharge amount approximates the predetermined optimal amount.
