Claim Text:
1. An electron beam curable ink for use in an indirect printing process comprising: a radiation curable material selected from the group consisting of a curable monomer, a curable oligomer, and mixtures thereof; and a surfactant comprises silicone and is present in the amount of from about 0.1% to about 5% based on the total weight of the ink; wherein the ink is partially cured to a viscosity of from about 5,000 to about 1,000,000 cps by exposing the ink to a first electron beam irradiation at a dose of from about 0.1 Mrad to about 1.0 Mrad before transfer from an intermediate transfer member to a final substrate, and further wherein the ink is exposed to a second electron beam irradiation at a dose of from about 1.0 Mrad to about 4.3 Mrad to induce complete crosslinking to form an image.
