ABSTRACT:
Ink jet printers used for printing large characters employ a separate solenoid valve for each drop stream which forms part of a printhead matrix. By optimizing the frequency response of the nozzle/valve sub system (primarily the connecting tubing), higher operating frequencies can be obtained. It has been found that a ratio of six to one between subsystem resonant frequency and operating frequency provides greatly improved printing.
