Abstract
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.
