Abstract
A printing apparatus includes a rotatable anilox roll engageable with a rotatable print cylinder for transferring ink thereto. A rotatable wipe roll and a doctor blade head are selectively engageable with different portions of the anilox roll to provide alternative wipe roll and doctor blade inking systems. Preferably both inking systems have substantially common ink supply and ink return paths with a valve being selectively operable to direct the ink supply path to either the wipe roll or the doctor blade head. Facilities for effecting a wash cycle may be provided to wash either inking system after use. Preferably an interlock arrangement prevents changing in use between the two inking systems until a wash cycle has been completed.
