Abstract
A dampening system for an offset printing press system uses an intermediate roll between the press system and dampening rolls to create multiple slipping nips. By driving the intermediate roll at a surface velocity greater than the dampening roll speed and less than the press system speed, the speed ratio at each slipping nip may be reduced.
