    Publication number: 20080282917
    Abstract: A plate cylinder includes a cylinder including a longitudinal axis and a centroid located at a geometric center of the cylinder. The cylinder also includes a slot for receiving both ends of a printing plate; the cylinder including a counter balance hole extending axially in the cylinder and being displaced from the longitudinal axis, the counter balance hole balancing the slot; and the cylinder including a mass balance hole extending axially in the cylinder and being displaced from the longitudinal axis, the mass balance hole balancing the plate cylinder. The cylinder further including at least one hole extending axially in the cylinder and being displaced from the longitudinal axis of the cylinder to reduce the variation in products of inertia as the plate cylinder rotates. A cylinder is also provided. A method is also provided.
