In many cases, yes. Removing dried ink and residue from clogged cells can restore more consistent ink transfer and improve print quality that had degraded due to buildup.

This depends on ink type, run frequency and how quickly cells begin clogging in your specific operation, so cleaning intervals are best set based on observed print quality rather than a fixed schedule.

When frequency and cycle time are set appropriately for the roller’s ceramic coating, ultrasonic cleaning is generally considered safe and is widely used in the printing industry for this reason.

Cycle time depends on the roller’s cell count, ink type and how heavily it’s clogged, so it’s best confirmed for your specific rollers rather than assumed from a general figure.
