Abstract
A liquid discharge apparatus includes a liquid discharge head and circuitry. The liquid discharge head has a nozzle hole from which a liquid is discharged and includes a valve to open and close the nozzle hole and a valve driver to drive the valve. The circuitry causes the valve driver to drive the valve to open the nozzle hole for a valve opening time to discharge the liquid onto an object, and changes the valve opening time based on a head pressure applied to the liquid in the liquid discharge head.
