1. An indirect printing system comprising:
an intermediate transfer member; and a photocurable ink, the photocurable ink comprising
a radiation-curable material selected from the group consisting of a radiation-curable monomer, a radiation-curable oligomer, and mixtures thereof,a first photoinitiator that absorbs radiation at a first wavelength spanning about 370 to about 420 nm,a second photoinitiator that absorbs radiation at a second wavelength from about 250 to about 370 nm, anda surfactant, wherein the surfactant and a total amount of photoinitiator comprising the first photoinitiator and the second photoinitiator are combined with the radiation-curable material to produce a composition comprising a photocurable ink transferable to the intermediate transfer member, wherein the photocurable ink is partially cured to a viscosity of from about 5,000 to about 1,000,000 cps before the composition is transferred from the intermediate transfer member to a final substrate, and wherein the photocurable ink, after partially-curing, is transferred to the intermediate transfer member. |
