摘要： An ink-jet print apparatus adapted to prevent stain defects is disclosed.The ink-jet print apparatus includes: first to third head portions configured to form red, green, and blue color filters on a substrate; a plurality of nozzles provided in each of the first to third head portions; a camera, above the substrate, configured to photograph a transmittance of each of sub-pixels in which the red, green, and blue are formed; a light emission unit, under the substrate opposite to the camera, configured to emit light on the sub-pixel; and an injection quantity control unit configured to compare the transmittance of each sub-pixel photographed by the camera with a previously prepared reference transmittance and to compensate the injection quantity of the nozzle.
