PowerSonic™ The Ultimate in Plating
    US Patents 5,925,231; 6,197,169; 6,231,728 - other patents applied for, European patent applied for

Over the years, Chema Technology, Inc. has been very involved in research and development to improve gravure cylinder plating and finishing. Using existing production tanks, Chema conducted ultrasonic testing that resulted in a breakthrough in 1997.

Ultrasound speeds up the electromechanical separating process of plating by causing hydrogen bubbles to collapse, cleaning the solution and making all contaminants pass through the filter and not onto the cylinder. More importantly, this results in a more even grain structure across the cylinder than is possible with conventional plating methods.

The significance for the printing process? Chrome flaking is reduced. The smoother surface allows the pressure of the doctor blades to be reduced. The harder chrome and smooth surface without hydrogen buildup allows increased longevity of the cylinder in the press. Also, a better ink release with smoother surface inside the cell should result in a higher quality print.

The end result of plating with PowerSonic™ is a speeding up of the conventional process, more consistency in the plating process, and simplification of the plating procedure.
