Patent abstract
The present invention contains a printing apparatus and a method, e.g., for ejecting inks (i.e., pure liquids, mixtures, colloids, etc.) for a very broad range of physical properties (such as viscosity). Acoustic forces 3a may be generated by an emitter 1 and a reflector 2 to detach droplets 10 from a nozzle 6. The ink may be advanced through the nozzle 6 by a standard back pressure system 5. A reflectorless chamber 7 may enhance acoustic forces 8a and the droplets 10 may be ejected at a bottom 9 of said chamber 7, so that droplets 10 may be deposited on any substrate 11.
