Abstract
A method for reducing vibrations in a printing press, the printing press having a first plate cylinder independently registrable from a second print cylinder. The method includes the steps of determining a lateral position of the first vibrator, roll with respect to the second vibrator roll and rotating the first plate cylinder with respect to the second plate cylinder so as to change the lateral position of the first vibrator roll with respect to the second vibrator roll. A printing press has a controller receiving an input from at least one sensor, the controller rotating the first plate cylinder with respect to the second plate cylinder so as to alter a phase between the first vibrator roll and the second vibrator roll as a function of the input.
