Spring Cleaning

Ultrasonic

Ultrasonic cleaning machines de-ink aniloxes using sound waves. For the best results, aniloxes are soaked in a cleaning solution for 90 percent of the cleaning time. Then the ultrasonics are turned on and sound waves create microscopic bubbles that implode against the roll, agitating the ink loose and away. The key to ultrasonics is the right combination of chemical soaking solution, heat, and time that the roll is exposed to the sound waves, according to Marty Cansler, national sales manager of pressroom products for Max Daetwyler.
