An apparatus to align a substrate and a print head having a plurality of orifices so as to perform a printing operation by ejecting ink on the substrate comprises a camera unit provided between the substrate and the print head to photograph the plurality of orifices of the print head and the substrate so as to align the print head and the substrate, and a camera moving part to movably support the camera unit and to move the camera unit between the substrate and the print head. Thus, the aligning apparatus has a simple configuration that may be easily installed and may be controlled precisely. The aligning apparatus may also be used with opaque substrates.

Aligning apparatus

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.
