Abstract: A method for printing a digitally-stored image on the surface of a cylindrical object comprises the steps of axially moving the object along a line of travel that is aligned with the object's long axis until it is underneath one or more printheads, each of which have a plurality of ink nozzles that may be arranged in one or more columns while simultaneously rotating the object with respect to the printheads and simultaneously causing a pre-determined number of nozzles to eject ink onto the surface of the object.

Abstract: An ink jet printer for printing on an at least partially cylindrical objects comprises one or more printheads positioned above a line of travel and a carriage assembly configured to hold an at least partially cylindrical object axially aligned along the line of travel and to position said object relative to the printheads, and then rotate the object relative to said one or more printheads. The printer also includes a curing device located along the line of travel and configured to emit an energy suitable to cure the deposited fluid.

Abstract: An ink supply system for ink jet printers includes a recirculation tank coupled to a recirculation pump configured to provide a substantially pulseless flow of ink. A heating assembly having an ink conduit formed into a spiral in thermal contact with at least one heating element receives ink from the pump and outlets to a sensor assembly with temperature and pressure sensors that measure ink parameters both as the ink enters a printhead and is returned from the printhead. The returned ink is then ported to a recirculation tank from which the pump draws the recirculating ink. An air pump is coupled to the recirculation tank in order to maintain a substantial vacuum within the tank.
