Abstract
A liquid discharge apparatus includes a head array including heads each having nozzles to discharge liquid onto a recording medium, arranged as a nozzle line in a sub-scanning direction; a moving part to move the head array alternately in the scanning direction and in the sub-scanning direction perpendicular to each other while discharging or not discharging the liquid; and a controller including a memory and a processor. The processor adjusts image data for juncture areas of two heads adjacent to each other in the sub-scanning direction; and drives the head array to discharge the liquid from the nozzles while the moving part moves the head array. The adjusting adjusts the image data such that the image data is thinned to make print rates for the juncture areas smaller at ends of the nozzle lines, and the print rates vary among the juncture areas.
