In a printing press having a chamber body, a doctor blade clamping assembly includes a leaf spring having a plurality of leaves assembled together in overlying relation to each other, the leaves being of different lengths; bolts extending through the leaf spring and secured to the chamber body, the bolts engaging the leaf spring to secure the leaf spring to the chamber body in at least partial overlying relation to a doctor blade such that the leaf spring applies a biasing force to the doctor blade to clamp the doctor blade to the chamber body; an inflatable bladder positioned in a recessed area in the chamber body and at least indirectly engaging the leaf spring when the bladder is inflated so as to bias the leaf spring in a direction away from the doctor blade to release the doctor blade from the biasing force of the leaf spring; a conduit connected with the bladder; a spacer positioned in the recessed area between the bladder and the leaf spring; a bladder control connected with the conduit, the bladder control supplying a pressurized gas through the conduit to the bladder to inflate the bladder and removing the pressurized gas from the bladder through the conduit to deflate the bladder; and a stop engaged with the chamber body and the leaf spring for limiting movement of the leaf spring in a direction away from the doctor blade.
