ABSTRACT:
An inking system for a rotary printing press, such as a flexographic printing press, including a pair of axially spaced doctor bars each having a pair of doctor blades to define ink chambers between the doctor bars and an inking roller. An ink separator plate is positioned between and in contact with the innermost ends of the doctor bars and includes a curved concave end face for intimate surface contact with the inking roller, to prevent intermixing of the separate ink colors that are provided to the respective ink chambers. The ink separator plate extends at right angles to the axis of the inking roller, and is pivoted on a pin that has an axis that is parallel to the axis of the inking roller to permit the plate to be urged by gravity into surface contact with the outer periphery of the inking roller.
