ABSTRACT:
A density-adjusting method of a liquid-discharging apparatus having a head including a plurality of juxtaposed liquid-discharging units having respective nozzles, forming dots by landing droplets discharged from the nozzles onto a droplet-landing object, and providing half tones by arranging a dot array is provided. A density-measuring pattern including all pixel trains lying in the main scanning direction with a constant density is formed, the density of the pattern is scanned so as to obtain density information and the relationship between the number and the density of droplets with respect to each pixel train. Upon receipt of a discharge command signal, based on the obtained data with respect to each pixel train, the density of the pixel train corresponding to the discharge command signal is adjusted by making the number of droplets to be actually discharged from the nozzles different from that of droplets discharged according to the discharge command signal.
