Abstract
An ink jet printing head comprising an array of successive pairs of cavity plates and transducer plates. The transducer plates are one-piece elements composed of piezo-ceramic material and can have multiple diaphragms on opposing faces matching with cavities in the cavity plates. Many such pairs of cavity plates and transducer plates can be joined together to form a printing head which can achieve a very high density of nozzles, specifically, on the order of 150 to 200 nozzles per inch.
