ABSTRACT:
A flexographic printing plate cleaner comprises a linear actuator operably mounted relative to a plate cylinder carrying a flexographic printing plate; a frame carried by the linear actuator for movement along a path parallel to an axis of rotation of the plate cylinder; and a double-acting three-position cylinder carried by the frame. The cylinder includes a first piston rod a retracted position, a first extended position and a second extended position. A backing plate secured to an exterior end of the first piston rod and movable therewith. A cleaning pad is disposed in front of the backing plate and adjacent the flexographic printing plate such that the cleaning pad engages the printing plate at a first pressure when the first piston rod is at the first position, and at a second higher pressure when the first piston rod is at the second position.
