Tips & Tricks: Alcolor Dampening System Adjustment

Basic adjustment of the dampening system should be performed with a clean roller with two thin paper strips (approximately 0.05 mm thick). The wide paper strip covers the rubber roller, while the narrow strip acts as a feeler gauge. This means that the greater resistance of the rubber roller is not felt. The narrow strip slips between the wide paper strip and the smooth distributor roller. There is an exact description of the method in the operating instructions.

If the Alcolor dampening system is adjusted or checked with ink, be aware that when the strip is formed an unintended rolling movement occurs from the application roller to the damping form roller. This makes the press strip wider. If there is a suitable waiting time (approximately 30 seconds), the "inner" strip can be properly assessed.
