Abstract
A spray dampening device for a printing apparatus, the spray dampening device comprising a plurality of spray nozzles. The spray nozzles are each cycled at a predetermined frequency and at an individual nozzle phase shift with the individual phase shifts being synchronized so that an effective frequency of spray bursts applied to target surface of the printing apparatus is greater than the predetermined frequency. Dampening system performance may be improved without the implementation of new individual nozzle technology. The benefits of a pulsed dampener system are maintained while system performance approaches that of a continuous dampener.
