Abstract
Official abstract text for this publication.
An ink leveling device for controlling a temperature difference across a substrate having ink disposed on the upper surface, the device including a cooling device cooling a bottom of a substrate to a first temperature that is lower than a viscosity threshold temperature of the ink, a heating device heating the upper surface of the ink layer to a second temperature that is greater than the viscosity threshold temperature of the ink and a device applying shear force across the upper surface of the ink layer.
First claim
