Zusammenfassung:PROBLEM TO BE SOLVED: To provide a method for easily detecting at least one among an intaglio printing pressure, the contact pressure of an intaglio form roller and the contact pressure of a wiping roller contacting with an intaglio plate cylinder in an intaglio printing machine and its detecting system. SOLUTION: As a thrusting pressure controlling method, a thrusting pressure detecting apparatus for detecting at least one among the thrusting pressure of an impression cylinder (2) against an intaglio plate cylinder (1), that of the form roller (3) against the intaglio plate cylinder (1) and that of the wiping roller (4) against the intaglio plate cylinder (1) is provided on the rear surface of an intaglio printing plate surface (6). As one example of the thrusting pressure detecting apparatus, a strain gauge (5) is provided. During one revolution of the intaglio plate cylinder (1), the strain gauge (5) detects at least one among the thrusting pressure of the impression cylinder (2) against the intaglio plate cylinder (1), that of the form roller (3) against the intaglio plate cylinder (1) and that of the wiping roller (4) against the intaglio plate cylinder (1).
