ABSTRACT:
An exact setting of an ink supply at a doctor blade of a printing press, in particular an offset printing press, is performed with special set screws, which are positioned in appropriate through-bores directed to sections of the doctor blade. It is possible to make exact, fine adjustments with two-piece set screws having a duct-adjusting screw and a set bolt which have threads with different leads. Each set screw has a counter so that these adjustments can be made without loss of time and paper.
