Abstract
A printing press comprises a cylinder having an outer surface and a plurality of air holes for providing air to the outer surface. A sound-damping material is located on a section of the outer surface and an axially-removable printing sleeve fits over the outer surface. Also disclosed is a method for reducing noise from a printing press comprising the steps of providing air through air holes in a cylinder having a free end to aid in placement or removal of an axially-removable printing sleeve, and providing a sound-damping surface to an outer surface of the cylinder at the free end.
