Abstract:
Apparatus for providing an image on a receiver in response to a digital image, comprising:a) a set of print heads for ejecting UV radiation curable ink drops on the receiver to form image pixels on the receiver;b) a single UV radiation light source associated with the print head set for applying radiation for curing inks by hardening or solidifying ink drops on the receiver;c) means for providing relative movements between the receiver, the print heads, and the UV radiation light source; andd) control means coupled to the relative movement means for causing the relative movement means to provide relative movements in at least two directions between the receiver, the print heads, and the radiation source, and for causing the print head to print a print area in multiple passes in response to the digital image to deliver radiation curable inks in multiple layers to the area of the receiver and for curing each delivered ink layer during each printing pass to thereby produce an image on the receiver.
