Abstract: An inkjet printing apparatus includes: a stage, which reciprocates in forward and reverse directions opposite to each other and has a target substrate disposed thereon; an inspection device including a film disposed outside the stage and a measurement unit which measures an inspection pattern provided on the film; and a head assembly, which moves along one direction crossing the forward direction and has a plurality of heads which supplies a liquid composition to the target substrate. The head assembly moves in the one direction to overlap the film and sprays the composition onto the film to form an inspection pattern.
