ABSTRACT:
A system and a method for making fountain adjustments in a printing press. A press control panel has a plurality of key pairs for bidirectionally controlling associated fountain adjusters, and the system provides for zonal adjustment by defining zones which include a plurality of fountain adjusters and simultaneously adjusting all of the adjusters in a defined zone. A zone definition begins by detection of simultaneous actuation of both keys in a pair, and a zone is defined by actuation of a further key, the zone encompassing all adjusters lying between the actuated key pair and the further key. After definition of a zone, all of the adjusters in a zone are controlled by operation of one or two keys in the zone. Flexibility is provided to adjust all adjusters in the same direction and by the same amount, or to interpolate adjustments between adjusters.
