Beschreibung
Zusammenfassung:	An ink composition including at least one component selected from the group consisting of a curable monomer and a curable oligomer; at least one non-radiation curable poly-alpha-olefin; at least one photoinitiator that absorbs at an ultraviolet light-emitting diode wavelength; and an optional colorant. A process of digital offset printing including applying an ink composition onto a re-imageable imaging member surface at an ink take up temperature, the re-imageable imaging member having dampening fluid disposed thereon; forming an ink image; transferring the ink image from the re-imageable surface of the imaging member to a printable substrate at an ink transfer temperature; wherein the ink composition comprises at least one component selected from the group consisting of a curable monomer and a curable oligomer; at least one non-radiation curable poly-alpha-olefin; at least one photoinitiator that absorbs at an ultraviolet light-emitting diode wavelength; and an optional colorant.
