Abstract

A dampening unit for an offset printing machine having an applicator roller including a central section and two oppositely disposed tapered end sections to prevent the transference of excessive amounts of dampening medium to the printing plate is disclosed. The boundaries between each of the end sections and the central section of the applicator roller are located adjacent predetermined regions defined on the plate cylinder to ensure a uniform dampening medium film is produced across the entire format width of the material to be printed.
