ABSTRACT:
A printing station for use in a flexographic printing press. The printing station has a frame to which is attached supports for holding a doctor roll, an anilox roll and an impression roll. Adjustable mechanisms are provided for adjusting these rolls such that a plate cylinder may be removed and reinserted, without the use of tools, and without any need to readjust the adjustable mechanisms. The doctor roll and the anilox roll may also be removed without the use of tools. Two printing stations may be used to print alternately while a web having substrates moves continuously through the stations. This is achieved without significant waste because of the ability to quickly change plate cylinders without readjustment of the printing station.
