Vibrations in printing machines are serious problem, which influences on the run of printing process and the quality of the printouts as well. Ones of the most important sources of vibrations are printing units, in which periodically changing stiffness excites parametric vibrations. In this paper, printing unit of offset printing machine is modelled as a two degree-of-freedom system, which is described by a system of parametric differential equations. Some analyses of this model’s behaviour are presented as well as conditions, in which parametric resonance in such systems may occur.
