methods the acoustic world around with doppelschichtkonfiguration of print head

摘要

This invention relates to a method and apparatus for acoustic ink printing using a bilayer configuration. More particularly, the invention concerns an acoustically actuated droplet emitter (40) which is provided with a continuous, high velocity, laminar flow of cooling liquid (23) in addition to a stagnant pool of liquid (32) to be emitted as droplets.
