Abstract
The present invention provides a method and apparatus for cleaning a coating material from a surface of a print substrate mounted on the plate cylinder of a printing press using an ultrasonic acoustic cleaning apparatus. The method comprises: applying a cleaning solution onto a surface of the print substrate, rotating the plate cylinder to displace the print substrate under an ultrasonic acoustic cleaning apparatus to dislodge a coating material from the surface of the print substrate, and removing the dislodged coating material and the cleaning solution from the print substrate using a vacuum system.
