Liquid discharge method, non-transitory computer-readable storage medium storing drive pulse determination program, and liquid discharge apparatus

A liquid discharge method of using a liquid discharge head including a drive element and a nozzle to discharge a liquid from the nozzle by applying a drive pulse to the drive element, the method comprising:

• an acquisition step of acquiring a recording condition including a first discharge characteristic of the liquid from the liquid discharge head and a second discharge characteristic of the liquid from the liquid discharge head, the second discharge characteristic being different from the first discharge characteristic;
• a determination step of determining the drive pulse to be applied to the drive element, based on the recording condition;
• and
• a driving step of applying the drive pulse determined in the determination step to the drive element, wherein
• in the determination step, the drive pulse is determined by a determination method subjected to weighting in which a weight of the first discharge characteristic is greater than a weight of the second discharge characteristic,
• the drive pulse includes a plurality of changeable factors,
• the plurality of factors include at least a first factor and a second factor different from the first factor, and
• in the determination step, a drive result when the drive pulse is applied to the drive element while the first factor is fixed and the second factor gradually changes is acquired, and the one drive pulse to be applied in the driving step is determined based on the drive result, among the plurality of the drive pulses.

A non-transitory computer-readable storage medium storing a drive pulse determination program for determining a drive pulse to be applied to a drive element in a liquid discharge head including the drive element that discharges a liquid to a nozzle in accordance with the drive pulse, the program causing a computer to realize:

• an acquisition function of acquiring a recording condition including a first discharge characteristic of the liquid from the liquid discharge head and a second discharge characteristic of the liquid from the liquid discharge head, the second discharge characteristic being different from the first discharge characteristic;
• and
• a determination function of determining the drive pulse to be applied to the drive element, based on the recording condition, wherein
• 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 being to be applied after the first potential, and the third potential being to be applied after the second potential, and
• in the determination function, the drive pulse is determined by a determination procedure subjected to weighting in which a weight of the first discharge characteristic is greater than a weight of the second discharge characteristic.
