Abstract

A liquid discharge apparatus (100, 100A, 100B) including a head (1a, 1b, 1c, 1d) having a nozzle row with nozzles in line, a conveyor (102, 108, 109) to convey a discharge target medium (101) in parallel with alignment of the nozzle row, and a controller (200, 200A) that controls a liquid discharge in association with conveyance of the discharge target medium (101). The controller (200, 200A) determines, with a test pattern, whether the nozzles of the head (1a, 1b, 1c, 1d) discharge a color liquid. When forming the test pattern without discharging droplets of the color liquid from adjacent nozzles simultaneously, the controller (200, 200A) discharges a droplet from a first nozzle of the adjacent nozzles, suspends the liquid discharge for a predetermined period of conveyance of the discharge target medium (101), and discharges a droplet from a second nozzle of the adjacent nozzles after the predetermined period.
