Liquid droplet discharge device, liquid droplet discharge method, and non-transitory storage medium storing program

A liquid droplet discharge method that is to be executed by a liquid droplet discharge device,

• wherein the liquid droplet discharge device includes
• a plurality of pressure chambers in communication with a plurality of nozzles, wherein the pressure chambers are configured to store ink;
• an oscillation plate that is disposed over the pressure chambers, so that an elastic wall of each of the pressure chambers is formed;
• pressure generating elements that are disposed to face the plurality of the pressure chambers through the oscillation plate;
• a drive waveform generator configured to generate, for each of the nozzles, a drive waveform by using, as an input, drive waveform data that indicates a shape of the drive waveform for driving the corresponding pressure generating element;
• and
• a residual oscillation detector configured to detect residual oscillation that is generated in each of the pressure chambers after driving the pressure generating elements, and
• wherein the method includes a step of correcting, during printing, the drive waveform data for each of the nozzles, based on a detection result by the residual oscillation detector.
