US Patent 7370928 Droplet discharge control method and liquid discharge apparatus

The method of controlling droplet discharge for a liquid discharge apparatus which discharges droplets from a discharge head onto a discharge receiving medium, the method comprises the steps of: successively discharging a plurality of droplets from the discharge head so that at least some of the droplets discharged to mutually adjacent deposition points on a surface of the discharge receiving medium overlap; and carrying out at least one form of control selected from control which modifies a droplet discharge amount so that the droplet discharge amount of at least some of the droplets of the plurality of successively discharged droplets becomes relatively larger sequentially, and control which modifies flight velocity of the droplets so that the flight velocity of at least some of the droplets of the plurality of successively discharged droplets relatively increases sequentially.
