ABSTRACT:
A method and apparatus for generating three-dimensional decoration on a substrate. Controlled deposition of the decoration material on the substrate is achieved through formation and manipulation of an ink droplet at the end of a dispensing nozzle. The ink droplet is maintained by coordinating the delivery rate of the ink through the dispensing nozzle with the dispensing nozzle height and velocity. The ink droplet is optimally maintained to provide a controlled wetting of the substrate surface for deposition of a wide variety of inks.
