Abstract
Ink duct for offset or relief printing machines having an ink metering device adjustable with respect to a doctor roller for varying a gap therebetween, includes an ink metering device having adjusting elements for varyingly adjusting the gap zonewise, the adjusting elements being formed with respective bracing and metering regions disposed adjacent one another in axial direction of the doctor roller, the adjusting elements at the respective bracing region thereof being continuously spring-biased into at least indirect contact with the doctor roller and, at the respective metering region thereof, being adjustable to a varying spacing thereof from the doctor roller so that the respective spacing of the respective metering region from the doctor roller determines the ink gap in a respective zone.
