ABSTRACT:
An apparatus and method for electroplating and deplating a rotogravure cylinder out of a plating solution using ultrasonic energy is disclosed. The apparatus includes a plating tank adapted to rotatably maintain the cylinder and to contain a plating solution so that the cylinder is at least partially disposed into the plating solution. The apparatus also includes a mounting structure mountable within the tank partially on each side of and generally below the cylinder, along with a plurality of conductors at least partially disposed within the plating solution. A current source is electrically connected to the upper portions of the conductors and to the cylinder. An ultrasonic system to introduce wave energy into the plating solution includes at least one transducer element mountable within the tank and a power generator adapted to provide electrical energy to the transducer element. A holding tank having a circulating pump and heating and cooling elements for the plating solution may be provided. A method of preparing a rotogravure cylinder to be used in a printing operation is also disclosed.
