More Features

The basic component of the QUAD-STACK is the UPM (Universal Printing Module) a compact web-fed offset printing unit that prints a single color on both sides of the web of paper. The UPM contains four solid stainless steel printing cylinders: two plate & two blanket cylinders.


UPM's are are configured to be placed one on top of the other with each added module enabling the printing of one additional color on each side of the web. These "stackable" modules are either mounted above a reel stand or a base frame.
