Abstract
The drive waveform determination method includes a first step of setting a condition of the first discharge characteristic, a second step of acquiring the first discharge characteristic and the second discharge characteristic that are measured when a candidate waveform is used as a waveform of the drive pulse, a third step of determining whether the first discharge characteristic meets the condition, and a fourth step of, when it is determined in the third step that the condition is met, evaluating a candidate waveform by performing a superior comparison using the second discharge characteristic. The waveform of the drive pulse is determined by an optimization process in which at least the second step, the third step, and the fourth step are repeated.
