Abstract
A printing press including a frame and a central impression drum rotatably supported on the frame. A plurality of first side printing stations is circumferentially spaced about the central impression drum and in communication therewith. Each of the plurality of printing first side printing stations is adapted to print an image on a first side of a substrate. A perfecting printing station is disposed at a position about the central impression drum. The perfecting printing station includes a multi-purpose drum having a substrate retainer for securing the substrate thereto. The multi-purpose drum forms an impression cylinder and is in communication with an image transfer cylinder for imparting an image on a second side of the substrate. An ink fixing unit is disposed between the first side printing stations and the perfecting station. The ink fixing unit fixes the image on the first side of the substrate prior to the image being imparted on the second side of the substrate by the perfecting station.
