Abstract
A doctor blade holder and adjustment mechanism that may be utilized with a flexographic printing system. The doctor blade holder and adjustment mechanism may utilize a constant displacement of the doctor blade against an anilox roller, rather than a constant force, to reduce ink build up on the back side of the doctor blade, and subsequently, intermittent dropping of the accumulated ink onto the post-shearing side of the anilox roller (“spitting”). The doctor blade holder and adjustment mechanism may provide adjustability of a combination of doctor blade pressure, angle and displacement.
