Claim 0:
1. A droplet discharge apparatus comprising:
a discharge device configured to discharge droplets of a plurality of droplet types according to a plurality of drive waveforms;
a plurality of waveform generation units configured to individually generate drive waveforms used to discharge each of the plurality of droplet types;
a plurality of correction units configured to 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;
a drive unit configured to cause 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; and
a speed measurement unit configured to measure a speed of a droplet for each of the plurality of droplet types,
wherein the plurality of correction units are configured determine a correction magnification for each of the plurality of droplet types and correct the speed based on a measurement result of the speed by the speed measurement unit.
