Abstract
An ink jet print head for a continuous ink jet printer includes an orifice plate defining an elongated array of ink jet orifices, an ink manifold for supplying ink to the orifices in the orifice plate, and a shear mode piezoelectric transducer mechanically coupled to the orifice plate for vibrating the orifice plate sufficiently uniformly along the length of the array of ink jet orifices to achieve synchronous stimulation. The use of a shear mode piezoelectric transducer eliminates mode cross coupling thereby allowing high frequency stimulation in long ink jet print heads.
