Abstract
A contact pressure adjusting method and a contact pressure adjusting apparatus for a printing press, which can adjust a contact pressure automatically and always highly accurately without the influence of mechanical oscillations (disturbance such as noise), are provided. For this purpose, the contact pressure (load) of a wiping roll on an intaglio cylinder is converted into the torque value (electric current value) of a wiping roll drive motor, and given as feedback to a wiping roll contact pressure adjusting motor.
