Abstract:
A printer for transferring a phase-change ink onto a substrate includes components for conveying the substrate along a path through the printing machine, a printing station including a plurality of printheads disposed along the path and configured to transfer the phase-change solid ink onto the substrate as it is conveyed along the path, a plurality of metal backing rollers facing the plurality of printheads and arranged to support to the substrate passing between the backing rollers and the printheads, and a spreader station receiving the substrate from the printing station and configured to spread the phase-change solid ink on the substrate, the spreader station including a spreader roller and a metal pressure roller opposing the spreader roller. Each of the non-oiled metal rollers includes a coating that is oleophobic that has low adhesion toward the solid ink image but sufficient lateral friction as to not slide against the ink or paper web.
