ABSTRACT:
A method of manufacturing an ink stick for use in a phase change ink jet imaging device comprises heating phase change ink material to an extrusion temperature at which the phase change ink material is in a malleable state. The heated ink material is then extruded through an extrusion orifice to form an extruded element. A forging element is then pressed against the extruded element to form an ink stick.
