Abstract
A droplet discharge device includes a droplet discharge head, a feed reel, a drying chamber, a drying-gas-introducing device, a take-up reel, an imaging device, an analyzing unit and a control unit. The imaging device captures an image of functional liquid discharged from nozzles of the droplet discharge head onto a sheet member between the feed reel and the take-up reel with the sheet member having been dried in the drying chamber filled with a drying gas to achieve a predetermined humidity. The analyzing unit measures an area over which the functional liquid is deposited on the sheet member from each of the nozzles, and calculates a distribution of a discharge amount of the functional liquid. The control unit adjusts a voltage applied to the drive elements so that the discharge amount of the functional liquid from each of the nozzles approximates a predetermined optimum amount.
