Abstract
Provided is a method for automatically adjusting the contact pressure between an intaglio cylinder and a wiping roller that further limits the amount of defective prints generated. The method adjusts said contact pressure by changing the position of the wiping roller shaft center with respect to the intaglio cylinder shaft center using a contact pressure adjustment motor. At least the position of the wiping roller shaft center at low speed and the position of the wiping roller shaft center during printing operation for which the contact pressures have been optimized during a previous printing are stored. Before starting the current printing operation, the wiping roller is moved to the stored low speed position. Then when the current printing operation is started, the wiping roller is moved to the stored printing operation position.
