Abstract
A droplet discharge apparatus includes a discharge device, a plurality of waveform generation units, a plurality of correction units, and a drive unit. The discharge device discharges droplets of a plurality of droplet types according to a plurality of drive waveforms. The plurality of waveform generation units individually generate drive waveforms used to discharge each of the plurality of droplet types. The plurality of correction units individually correct the drive waveforms generated by each of the plurality of waveform generation units, using correction magnifications different corresponding to the drive waveforms generated by the plurality of waveform generation units, to generate correction waveforms. The drive unit causes the discharge device to discharge the droplets according to corrected drive waveforms generated by individually switching the drive waveform corresponding to the plurality of droplet types to the correction waveforms.
