The interval or spacing between rotational axes of adjacent cylinders in a rotary printing press, between a print-on position and a print-off position is accomplished using eccentric bushings for the cylinder journals of at least one of the cylinders. A printing gap between the two cylinders can also be varied using separate eccentric bushings. The effective eccentricity of the bushings extends parallel to a line connecting the axes of rotation of the cylinders. |
