Sheets are not the same as finished printed pieces. Both the HP Indigo Press and the Heidelberg QuickMaster DI print on sheets of 12"x18" stock. Our method is to fit as many final pieces into that 12"x18" sheet size as possible. A couple of examples:

2 8"x11" brochures would fit on a 12"x18" sheet rendering 1000 final brochures on a 500 sheet run.

4 6"x4" postcards with bleed would fit on a 12"x18" sheet rendering 2000 finished postcards on a 500 sheet run.
