LIQUID DISCHARGE APPARATUS AND LIQUID DISCHARGE METHOD

A liquid discharge apparatus includes: a liquid discharger to discharge a liquid from a nozzle; an imaging unit to capture a test pattern on a detection target member to acquire a test pattern image of the test pattern; circuitry configured to: cause the liquid discharger to discharge a first amount of the liquid per unit area from the nozzle onto a target object; cause the liquid discharger to discharge a second amount of the liquid per unit area larger than the first amount from the nozzle onto a detection target member to form the test pattern on the detection target member; perform image processing on the test pattern image on the detection target member acquired by the imaging unit; and determine presence or absence of abnormality in the nozzle based on the test pattern image obtained by the image processing.
