METHOD OF INSPECTING DISCHARGE OF FUNCTIONAL DROPLET DISCHARGE HEAD AND DEVICE FOR INSPECTING DISCHARGE OF FUNCTIONAL DROPLET DISCHARGE HEAD

摘要

PROBLEM TO BE SOLVED: To provide a method of inspecting the discharge of a functional droplet discharge head and a device for inspecting the discharge of the functional droplet discharge head by which the precise discharge inspection is carried out regardless of an inspection environment. SOLUTION: The discharge inspection method of the functional droplet discharge head 3 for inspecting the discharge performance of a plurality of the discharge nozzles 19 in the functional droplet discharge head 3 by discharging and depositing a solvent on a transparent glass plate G from the inkjet system functional droplet discharge head 3 into which the solvent of a functional liquid is introduced comprises: a sacrificial discharge step of sacrificially discharging the solvent along the deposition planned position on the glass plate G; an inspection discharge step of discharge the solvent to inspect on the deposition planned position on the glass plate G; and an inspection step of inspecting the discharge performance of the plurality of the discharge nozzle 19 by recognizing the deposition dots D of the solvent deposited by the inspection discharge as images.
