An offset printing apparatus for transferring a phase change ink onto a print medium having a phase change ink component for applying a phase change ink in a phase change ink image; an imaging member for accepting the phase change ink image from the phase change ink component, and transferring the phase change ink image from the imaging member to the print medium, and a transfix pressure member positioned in association with the imaging member, wherein the print medium passes through a nip formed between the imaging member and the transfix pressure member, and wherein the imaging member exerts pressure on the transfix pressure member so as to transfer and fuse the phase change ink image from the imaging member to the print medium, and further wherein the transfix pressure member includes a substrate; an intermediate layer positioned on the substrate; and an outer layer on the intermediate layer and the outer layer has a modulus of from about 1 to about 50 MPa, a thickness of from about 0.1 to about 2 mm, and wherein the pressure exerted at the nip is from about 750 to about 4,000 psi.
