Apparatus for adjusting the position of an ink blade at individual locations along its length, or the position of individual ink metering elements, relative to an ink ductor in a printing machine inking mechanism by rotatable set screws, having a position locking transmission between each set screw and the free end of the ink blade in the respective location or of the associated ink metering elements, for positively increasing or reducing the feed gap of the ink blade or ink metering elements which at its underside is fixedly connected to transversely extending pivot pins, in which each set screw is associated with a respective joint, having a pivot axis which extends transversely with respect to the set screw center line and parallel to the plane of the ink blade or ink metering elements, secured to one end of the associated set screw, which end, in use, projects out of an ink fountain into which the set screw is adjustably screwable and mountable, one end of a respective adjusting lever which is disposed approximately perpendicularly to the ink blade or ink metering elements being mounted pivotally and rotatably on the associated setting screw by means of the joint, while the other end of the lever is mounted pivotally on the respective pivot pin which is secured to the underside of the ink blade or ink metering elements.
