Abstract:
A discharge amount measurement method is configured to measure a discharge amount of a liquid discharged from at least one nozzle of a droplet discharge head. The discharge amount measurement method includes discharging the liquid as a droplet from the at least one nozzle of the droplet discharge head by a number of discharges that is set to obtain a measurable quantity by driving the droplet discharge head based on measurement discharge data that is substantially identical to data used when a drawing pattern is formed by discharging the liquid from the at least one nozzle of the droplet discharge head, measuring the discharge amount of the liquid discharged from the at least one nozzle of the droplet discharge head, and calculating an average discharge amount based on the discharge amount and the number of discharges.
