Determining the first and where appropriate Further eigenmodes take place, for example, by measuring torsional vibrations and / or Calculation. The vibrations are in their resonance ranges, i.e. when they occur counteracted the eigenmodes and natural frequencies of the printing machine in such a way that they are harmless to the printing process and therefore no duplication errors occur can. This is done by appropriate tuning of the natural frequency of the Mass of the torsional vibration damper, its spring rate and, if applicable, its Damping, as well as by arranging the torsional vibration damper on the critical Set the gear train.
