ABSTRACT:
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: discharging at least three droplets substantially simultaneously on a same line so that at least mutually adjacent droplets overlap when landing on the discharge receiving medium; controlling the droplet discharge so that a droplet discharge amount sequentially increases in a relative manner from a center area toward both ends of a dot group formed by the at least three droplets; and forming the dot group which contains the at least three dots with substantially a same diameter on the same line.
