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.
