ABSTRACT:
Oscillations caused by machine dynamics in a sheet-fed rotary offset printing machine affect the print quality. The disturbing oscillations are reduced in that printing units of the printing machine are offset relative to one another at a phase angle at which identical print events in at least two printing units occur simultaneously.
