Patent ID: 7520601

Claim:
A printing process for ink-jet printing a radiation curable image on a substrate comprising the steps of: a) applying a radiation curable liquid layer of a uniform thickness on at least a portion of said substrate and in an area intended to be imaged with radiation curable ink-jet ink; b) jetting a first radiation curable ink-jet ink droplet into said radiation curable liquid layer; c) curing said radiation curable liquid layer containing said radiation curable ink-jet ink droplet; and d) jetting a second radiation curable ink-jet ink droplet onto said cured layer of step c), wherein the thickness of said radiation curable liquid layer is adjusted uniformly in order to control the resolution of said radiation curable image such that the dotsizes of said first and second radiation curable ink-jet inks do not differ by more than 10% in diameter relative to the smallest dotsize when jetted at equal dpd (droplets per dot).
