Abstract: An inkjet printing method includes the steps of a) providing a first radiation curable composition curable by free radical polymerization or cationic polymerization; b) applying a layer of the first radiation curable composition on a substrate; c) curing the layer; d) jetting on the cured layer a second composition curable by a different polymerization than the first composition but selected from the group consisting of free radical polymerization and cationic polymerization; and e) curing the jetted second composition by a different polymerization than the first composition. The first composition includes a cationically polymerizable compound having at least one (meth)acrylate group present in the first curable composition in an amount of at least 25 wt % based upon the total weight of the first curable composition. An inkjet ink set may be used in the above inkjet printing method.

Abstract: A printing process is disclosed for ink-jet printing a radiation curable image on a substrate (14). First a radiation curable liquid layer (12) is provided on at least a portion of the substrate (14). Radiation curable ink-jet ink droplets (10) are jetted into the radiation curable liquid layer (12) and the radiation curable liquid layer (12) containing the radiation curable ink-jet ink droplets (13) is then cured. The resolution of the radiation curable image is controlled by uniformly adjusting the thickness of the liquid layer (12) for the dotsize of the radiation curable ink-jet ink jetted onto the cured layer.
