ABSTRACT:
Ink jet printing apparatus and method for improved accuracy of ink droplet placement on a receiver medium by compensating for jet direction variabilities between ink nozzles. More specifically, the invention is an ink jet printing apparatus and method for printing an output image on a receiver medium in response to an input image file having a plurality of pixels. The apparatus includes a print head and a nozzle integrally attached to the print head. The nozzle has a droplet placement characteristic (e.g., undesired placement of the droplet on the receiver medium) associated therewith. A waveform generator associated with the nozzle generates an electronic waveform including a plurality of electronic pulses to be supplied to the nozzle for adjusting the droplet placement characteristic. In this manner, the invention compensates for the undesired droplet placement characteristic, so that the droplet is accurately placed on the receiver medium irrespective of physical variabilities between nozzles.
