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.

Abstract: An apparatus and method for preventing condensation in machines for processing web-like material includes locating a condensation prevention device to reduce the amount of moisture near selected components to be protected and/or maintaining the surface temperature of components of a processing unit above the dew point of the surrounding air.

Abstract: An apparatus and method for preventing condensation in a selected area of a printing press, for example a dampener system, by, for example, controlling the air temperature surrounding the dampener system by cooling, heating or changing the humidity of the air such that the temperature difference between the components of the dampener system and the surrounding air has a desired value.

Abstract: The present invention relates to a method and apparatus for normalizing the zero points for each ink key in an ink fountain. The method and apparatus are useful in an ink fountain using an inker roll and a meter roll which are spaced by a gap, which gap can have possible variations in width. The method is performed when an operator programs the ink fountain controller with a reference point corresponding to the position of the ink key where ink is first transferred from the inker roll to the meter roll - - - the zero points for the ink keys. The reference points for all the ink keys are then normalized within the ink fountain controller, such that an operator display shows a uniform value for the individual reference points for all the ink keys.
