    摘要： A composition including at least one component selected from the group consisting of a curable monomer and a curable oligomer; at least one photoinitiator that absorbs at an ultraviolet light-emitting diode wavelength; and at least one photoinitiator that does not absorb radiation at the ultraviolet light-emitting diode wavelength. A process of digital offset printing including applying a 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. A process including combining at least one component selected from the group consisting of a curable monomer and a curable oligomer; at least one photoinitiator that absorbs at an ultraviolet light-emitting diode wavelength; and at least one photoinitiator that does not absorb radiation at the ultraviolet light-emitting diode wavelength; optionally, heating; and optionally, filtering; to provide an LED curable composition.

    摘要： An ink composition useful for digital offset printing applications includes a colorant and a radiation-curable water-dilutable compound. A process for variable data lithographic printing includes applying a dampening fluid to an imaging member surface; forming a latent image by evaporating the dampening fluid from selective locations on the imaging member surface to form hydrophobic non-image areas and hydrophilic image areas; developing the latent image by applying an ink composition including an ink component to the hydrophilic image areas, the ink composition having a radiation-curable water-dilutable compound, a colorant component, and water; and transferring the developed latent image to a receiving substrate, wherein the ink transfer efficiency is 90% or higher.
