ABSTRACT:
An orifice plate holder for use in the printing head of a jet drop printing apparatus which uses an orifice plate stimulated with a traveling wave to produce uniformly spaced drops of fluid for printing. The holder has at least one built in dampening device in the form of a sharply tapered end portion in a central elongated opening coextensive with and abutting the vibrating portion of the orifice plate. The tapered end portion acts as a damper to substantially attenuate the incoming traveling wave without causing a significant reflection.
