Abstract
An inspection method comprising discharging a transparent ink onto a transparent substrate; emitting ultraviolet rays from a first surface of the transparent substrate; detecting ultraviolet rays transmitted through the transparent substrate, from a second surface opposite to the first surface of the transparent substrate; and determining a discharge state of the discharging based on the detecting of the ultraviolet rays.
