ABSTRACT:
A ductor roller and a doctor blade together define an inking gap in a printing machine. One or more ink-control screws can press against the doctor blade to locally reduce the width of the gap. Each screw carries an abutment arrangement which is engageable with respective opposite sides of the machine's ink trough, depending upon the direction of rotation of the screw, so as to define two specific end positions for the screw and thus a maximum and a minimum width of the ink gap.
