Abstract: 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 comprising an ink component to the hydrophilic image areas, the ink composition comprising a radiation-curable water-dilutable compound, a colorant component, and optionally water; and transferring the developed latent image to a receiving substrate, wherein the ink transfer efficiency is 90% or higher.
