Abstract:
1. A contact pressure adjusting method for a printing press, the printing press including, a first rotating body, a second rotating body opposed to and making contact with the first rotating body, a second rotating body drive motor for rotationally driving the second rotating body, a contact pressure adjusting mechanism for adjusting a contact pressure of the second rotating body on the first rotating body, and a contact pressure adjusting motor for driving the contact pressure adjusting mechanism, the contact pressure adjusting method comprising: detecting an electric current value of a motor driver of the second rotating body drive motor, and driving the contact pressure adjusting motor in response to the detected electric current value, wherein the first rotating body is an intaglio cylinder having an intaglio supported thereon, the second rotating body is a wiping roll opposed to and making contact with the intaglio and supported rotatably, the second rotating body drive motor is a wiping roll drive motor for rotationally driving the wiping roll, and the contact pressure adjusting mechanism adjusts a contact pressure of the wiping roll on the intaglio, the contact pressure adjusting method further comprising setting the type of a material to be printed, the type of ink, the type of an image, and a material for the wiping roll as printing conditions, determining a reference electric current value of the wiping roll driving motor in accordance with the set type of the material to be printed, type of ink, type of the image, and material for the wiping roll, and during printing, driving the contact pressure adjusting motor so that an electric current value of the wiping roll drive motor equals the reference electric current value.
