INK FOUNTAIN APPARATUS AND METHOD OF ADJUSTING INK FLOW FOR A FLEXOGRAPHIC PRINTING APPARATUS

摘要

An ink fountain apparatus, method of method of adjusting printing characteristics in flexographic printing and a printing press system are disclosed. The apparatus may include a side plate, a roller disposed adjacent a first end of the plate, a back plate disposed adjacent a second opposing end of the side plate and a throttle disposed between the roller and the back plate. The throttle is mounted to the side plate and includes a back surface facing towards the back plate and a front surface facing towards the roller. The front surface includes a curved portion forming a tapering gap between the roller and the front surface of the throttle. A position controller is coupled to the throttle to selectively move the curved portion towards and away from the roller to adjust the volume of ink being transferred to the outer surface of the roller.
