The present invention is an apparatus for setting printing pressure in an offset printing press having an impression cylinder, an eccentrically journaled blanket cylinder, and an eccentrically journaled plate cylinder, each of the cylinders and each of the eccentric journals having an axis, wherein the printing pressure is to be adjusted between the blanket cylinder and the impression cylinder, as well as between the blanket cylinder and the plate cylinder, wherein a bearer ring to bearer ring contact exists between the blanket cylinder and the plate cylinder, wherein the impression cylinder, the blanket cylinder and the plate cylinder are in a basic printing position in which the axis of the plate cylinder, the axis of the eccentric journal of the blanket cylinder are disposed on a first straight-line, and the axis of the blanket cylinder is disposed on a second straight-line intersecting with the first straight-line at the axis of the eccentric journal of the blanket cylinder, at an adjustment angle between the intersecting first and the second straight-lines, and upon a change in the printing pressure between the blanket cylinder and the impression cylinder the blanket cylinder can be swung aside on its eccentric journal without a corresponding synchronous adjustment of the plate cylinder.
