Abstract
The fluid jet applicator of the present invention utilizes a piezoelectric crystal to artificially stimulate the fluid supply chamber with coherent acoustic energy to pruposely generate and exploit the acoustic standing waves therein. As a result, although sized droplets will be formed at substantially the same frequency from each orifice, individual droplets will be formed so as to be out of phase with its adjacent neighbors in accordance with the standing acoustic wave pattern. By selecting only a very short print time, e.g., such that only one or two drops are formed within such a time and by controlling the frequency of such print time, a wide range of aesthetically appealing, unique, random interference of patterns can be created. Patterns closely simulating natural wood grains including knot holes can be readily produced by the present invention. More, the present invention allows patterns to be modified with relative ease and remarkable flexibility.
