Abstract
A substrate inspecting apparatus to inspect a substrate printed on by a print head to determine whether a printing operation is being accurately performed includes a camera unit to photograph the substrate before the substrate is printed on and to photograph the substrate after the substrate is printed on, and a control part to compare a first image of the substrate before the substrate is printed on with a second image of the substrate after the substrate is printed on through the camera unit and to determine whether the printing operation is being accurately performed on the substrate. Thus, the substrate inspecting apparatus is capable of precisely inspecting the substrate during the printing operation and reducing processing time.
