Abstract
The present invention provides a method and apparatus for applying a coating material onto a print substrate mounted on a plate cylinder of a printing press. The method comprising: delivering a supply of the coating material to a distributive surface of an ultrasonic horn, the distributive surface controlling a flow of the coating material to an active edge of the ultrasonic horn, and atomizing the coating material at the active edge of the ultrasonic horn and directing the atomized coating material onto a surface of the print substrate. The present invention also provides a multi-purpose ultrasonic acoustic coating/cleaning system for applying a coating material onto, and cleaning the coating material from, a print substrate.
