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 generating illuminating light based on a color tone of a dot pattern of a droplet discharged from the droplet discharge head by selecting at least one of a plurality of illuminating light sources of different color tones and by modulating light illuminated from the at least one of the illuminating light sources based on the color tone of the dot pattern, capturing an image of the dot pattern while a photographed region including the dot pattern is being illuminated by the illuminating light, and inspecting the image of the dot pattern using image processing.
