Ink tribology is about the wear impact of ink on machine parts e.g.
the screen roll. Some extenders (the main component in the ink)
contain fillers that might cause wear. The ink tribology test allows
to evaluate if an ink has a lubricating or wear impact on machine
parts.
Why use the Technology Coaching Ink Tribology test procedure? 1. You want to be sure that the ink used is not damaging or wearing key parts of the ink metering system. 2. The screen roll is the main part in transfering ink to the print plate. Wear of the screen roll will result in less ink transfer. Ink will need more pigment to print the same colour resulting in higher cost 3. The impact of wear on screen roll and other machine parts will in the end result in downtime.
