Abstract: This invention is an improved apparatus and method for distributing ink in a printing press. In preferred embodiments, ink on an anilox roll is uniformly distributed on the roll by the scraping action of doctor blades against the roll surface. The blades are held in continuous engagement against the anilox roll by an adjustment mechanism which exerts a constant force against the doctor blades. The preferred adjustment mechanism is a cam or cams under the control of an actuator. The actuator causes each cam to rotate against a moveable support on which the doctor blades are mounted urging the doctor blades against the anilox roll. The actuator provides a constant force to each cam thereby causing the blades to be constantly urged against the anilox roll surface even as the blades are worn away by operation of the printing press.
