Printing press with perfecting station

A printing press comprising:

• a printing unit including;
• a frame;
• a central impression drum rotatably supported on said frame adapted to transport a sheet;
• a plurality of first side printing stations circumferentially spaced about said central impression drum and in communication therewith, said first side printing stations adapted to impart an image to a first side of the sheet being transported by said central impression drum;
• a perfecting printing station disposed about said central impression drum sequentially after said plurality of first side printing stations for imparting an image to a second side of the sheet, said perfecting printing station including a multi-purpose drum having a first sheet retainer attached thereto for securing the sheet to said multi-purpose drum, said multi-purpose drum forming an impression cylinder and being in rolling communication with an image transfer cylinder for printing an image on the second side of the sheet.

A printing press comprising:

• a frame;
• a central impression drum rotatably supported on said frame and adapted to transport a sheet;
• a plurality of first side printing stations circumferentially spaced about said central impression drum and in communication therewith for printing an image on a first side of a substrate;
• an ink fixing device for fixing the image on the first side of the substrate being pivotally secured to said frame and rotatable between a first position and a second position;
• and
• a hinge rotatably securing said ink fixing unit to said frame, said hinge including a bracket fixedly secured to said frame and an arm fixedly secured to said ink fixing device, said arm including a portion rotatably engaged with said bracket to permit rotation between said bracket and said arm.

A printing press comprising:

• a frame;
• a central impression drum rotatably supported on said frame and adapted to transport a sheet;
• a plurality of first side printing stations circumferentially spaced about said central impression drum and in communication therewith for printing an image on a first side of a substrate;
• an ink fixing device for fixing the image on the first side of the substrate being pivotally secured to said frame and rotatable between a first position and a second position;
• and
• an access opening to permit access to said central impression drum, said access opening being disposed adjacent to said ink fixing device such that said ink fixing device covers said access opening when in said first position and exposes said access opening when in said second position thereby permitting access to said central impression drum.
