Method for inspecting droplet discharge head, device for inspecting droplet discharge head, and droplet discharge device

摘要

A method for inspecting a droplet discharge head includes discharging a plurality of droplets on an inspection workpiece from a nozzle row of the droplet discharge head at least twice in different positions on the inspection workpiece thereby forming a plurality of dot pattern rows each including a plurality of dot patterns, inspecting each of the dot patterns included in a first dot pattern row among the dot pattern rows by sequentially acquiring, using an image processing, a predetermined inspection value of the each of the dot patterns determined based on a shape of the each of the dot patterns, and initiating inspection of a second dot pattern row among the dot pattern rows when inspection of the first dot pattern row is interrupted upon one of the predetermined inspection values sequentially acquired exceeding a predetermine threshold established in advance according to a type of the predetermined inspection value.
