Claim 6:
7. A droplet discharge apparatus comprising:
a discharge device configured to discharge droplets of a plurality of droplet types;
a first circuit configured to:
generate a first waveform to discharge a first droplet type of the plurality of droplet types; and
correct the first waveform at a first correction magnification to generate a first correction waveform;

a second circuit configured to:
generate a second waveform to discharge a second droplet type of the plurality of droplet types; and
correct the second waveform at a second correction magnification to generate a second correction waveform;

a third circuit configured to cause the discharge device to discharge the droplets according to corrected drive waveforms obtained as a result of switching the first correction waveform and the second correction waveform; and
a speed measurement unit configured to measure a speed of a droplet for each of the plurality of droplet types,
wherein the first circuit is configured to determine the first correction magnification for the first droplet type and correct the speed of the first droplet type based on a measurement result of the speed by the speed measurement unit;
wherein the second circuit is configured to determine the second correction magnification for the second droplet type and correct the speed of the second droplet type based on the measurement result of the speed by the speed measurement unit.
