An apparatus for the placement of a doctor blade bar against an ink dispensing roller in a web fed rotary printing press, said apparatus comprising:

• first and second doctor blade supporting base bodies, said first and second base bodies cooperating to form a doctor blade bar;
• a first counter strip having a flat front with a first edge on a lower surface of said first base body and a second counter strip having a flat front with a second edge on a lower surface of said second base body;
• first and second spaced doctor blade base support beams, said first and second spaced doctor blade base support beams each supporting said first and second doctor blade supporting base bodies;
• first and second spaced lifting strips on each of said first and second spaced doctor blade base support beams, said first lifting strip having a first inclined surface and said second lifting strip having a second inclined surface;
• and
• means engaging said doctor blade body to shift said first and second doctor blade supporting bar bodies on said first and second doctor blade base support beams to slide said first and second edges of said first and second counter strips along said first and second inclined surfaces of said lifting strips to move said doctor blade bar with respect to an ink dispensing roller.
