Abstract
A droplet generator for generating a plurality of streams of ink droplets in a continuous ink jet printer comprises a stimulator plate, and the capability of supplying ink to the stimulator plate. The stimulator plate is substantially planar and comprises a substrate, a flexible membrane having a line of nozzles, and an actuator for vibrating the membrane at a resonant frequency. During use, a standing wave is generated such that the line of nozzles is positioned on a locus of uniform vibrational amplitude.
