1. A droplet discharge apparatus, comprising:
a plurality of dischargers configured to discharge droplets, wherein the plurality of dischargers are arranged in a substantially linear direction, wherein each discharger of the plurality of dischargers comprises a plurality of nozzles configured to discharge the droplets, wherein each discharger of the plurality of dischargers is configured to controllably discharge a volume of droplets at a right end portion of said each discharger and at a left end portion of said each discharger, and
a control device configured to acquire characteristic values of adjacent left and right end portions of areas on which the droplets discharged by adjacent pairs of dischargers of the plurality of dischargers land, wherein the control device is configured to acquire the characteristic values from measurements of the end portions,
the control device being configured to adjust the plurality of dischargers such that a difference between the characteristic values at adjacent left and right end portions is within a range.
