Method of Operating a Dampening Unit in a Printing Press and Printing Press Having a Dampening Unit

摘要

A method of operating a dampening unit in a printing press includes providing a first dampening solution applicator roller rolling on a plate cylinder with slip relative to the plate cylinder, and a second dampening solution applicator roller simultaneously rolling on the plate cylinder. As the two dampening solution applicator rollers roll on the plate cylinder, there is a circumferential surface-speed difference between the first dampening solution applicator roller and the second dampening solution applicator roller. A printing press having a dampening unit is also provided.
