Abstract
A liquid discharge method of discharging a liquid from a nozzle of a liquid discharge head by applying a drive pulse to a drive element of the liquid discharge head includes an acquisition step of acquiring a recording condition, and a driving step of applying the drive pulse to the drive element. The drive pulse includes a first potential, a second potential different from the first potential, and a third potential different from the first potential and the second potential. The second potential is to be applied after the first potential, and the third potential is to be applied after the second potential. In the liquid discharge method, in the driving step, the drive pulse in which a time of the second potential varies depending on the recording condition acquired in the acquisition step is applied to the drive element.
