Reduced vibration printing press and method

A printing press comprising:

• a first plate cylinder;
• at least one first vibrator roll operatively connected to the first plate cylinder, the first vibrator roll being part of an inking unit or a dampening unit, the first vibrator roll moving laterally a certain amount for each rotation of the first plate cylinder;
• a second plate cylinder independently registrable with respect to the first plate cylinder in a circumferential direction;
• at least one second vibrator roll operatively connected to the second plate cylinder, the second vibrator roll being part of another inking unit or another dampening unit, the second vibrator roll moving laterally a certain amount for each rotation of the second plate cylinder;
• at least one sensor for sensing at least one of a lateral position of the first vibrator roll with respect to the second vibrator roll and a vibration of the printing press;
• and
• a controller receiving an input from the 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.
