A liquid discharge method and a liquid discharge apparatus

摘要

A liquid discharge method for discharging liquid by use of a liquid discharge head provided with liquid discharge nozzles (3) having a plurality of electrothermal converting members (4,5) capable of forming bubbles for discharging a liquid droplets comprises the step of using a driving condition in a range where the discharge speed of droplets is made substantially constant, while the amount of droplet is made changeable with the timing difference of driving when droplets are discharged by driving a plurality of the electrothermal converting members one after another. With the adoption of the method thus structured, high quality prints can be obtained without deviation of impact positions irrespective of the dot diameters, larger or smaller, for a significant enhancement of image representation.
