Abstract
Systems for leveling UV-curable gel ink include a leveling member having a conformable surface. The leveling member is a quartz tube rotatable about a longitudinal axis, and connected to a mandrel, with conformable VITON O-rings interposing the mandrel and the quartz tube. A UV source is disposed within the quartz tube, and configured to emit light through the quartz tube and the conformable surface onto a surface of a substrate passing through a leveling or pressure nip defined by the quartz tube and a backing member or pressure belt.
