A device for adjusting the amount of ink supplied for use in a printing press includes an ink blade disposed along the longitudinal direction of an ink fountain roller, ink adjusters respectively disposed for each of the longitudinally divided areas of the ink blade so as to move each area toward or away from the ink fountain roller and thereby adjust the gap between the ink blade and the ink fountain roller, ink blade position detectors for detecting the position of the ink blade adjusted by the ink adjusters, and the ink blade position control means for controlling the position of the ink blade through the ink adjusters on the basis of the zero point of the ink blade position detectors. The ink amount adjusting device further includes a zero point setting means for setting the value of each of the ink blade position detectors which is detected when the position of the ink blade has been zeroed by the ink adjusters as a zero point for detection upon which a new control operation of the ink blade position control means is to be based. |
