Abstract:
1. A method of printing an image on a substrate using a curable ink, the method comprising: generating an image wise pattern of spaced apart ink droplet locations for representing the image; separating the pattern into at least first and second different interleaved portions, each portion comprising a plurality of droplet locations and the droplet locations of each interleaved portion being spaced apart from each other; in a first printing pass, depositing ink droplets on the substrate at the drop locations of the first interleaved portion; in a final printing pass, depositing ink droplets on the substrate at the droplet locations of the second interleaved portion; and curing said deposited ink droplets by exposing the deposited ink droplets to curing radiation in a first partial curing step between the first and final printing passes and in a final curing step, wherein the first partial curing step is performed only after the first printing pass has been completed, wherein no curing is performed in either the first printing pass or the final printing pass, and wherein curing of the ink droplets deposited in the final printing pass occurs only during the final curing step.
