ABSTRACT:
Ink jet printing apparatus for forming a color ink image on a receiver in response to a digital image that includes a plurality of color planes, includes a plurality of color ink jet print head located at spaced apart transfer positions adapted to deliver color ink to the receiver to form a color ink image at an image receiving position, and the spacing between color ink jet print heads being selected to be a distance longer than the length of a color ink image to be formed on the receiver. The receiver is moved along a path past the color ink jet print heads, a registration mark formed on the receiver before the image receiving position. Two detectors are disposed adjacent to the path with each detector being disposed before a color ink jet print head for detecting the registration mark before printing the corresponding color plane of the ink image to produce a signal a control circuit is responsive to the digital image and the detector signals for actuating each color ink jet print head to form the corresponding color plane of the ink image on the receiver in registration with the previously printed color planes of the same ink image.
