ABSTRACT:
A method for improving droplet aim accuracy when operating an ink jet apparatus for ejecting ink droplets having velocities below 3.5 meters per second comprises the steps of first applying a primary electrical pulse to a transducer of the ink jet apparatus, for initiating the ejection of an ink droplet from an associated orifice via the production of a first pressure disturbance within the associated ink chamber of the ink jet; and thereafter prior to the break-off of the ink droplet from the orifice, applying an auxiliary pulse to the transducer, whereby the auxiliary pulse has a peak amplitude that is one-third that of the peak amplitude of the primary pulse, the latter causing a second pressure disturbance within the ink chamber of the ink jet, for causing the ink droplet to break off earlier and closer to the center of the orifice relative to the time and location of break-off in the absence of using the auxiliary pulse.
