Page 5 - "How to print on flexo?" By Petra Bteich

Flexographic printing is distinguished from other print methods
in the variety of substrates that can be printed on and it is
therefore a central process in packaging printing, although

gravure and offset are also used. Typical products printed by
the flexographic printing process include paper, film and foil,
multi-wall bags, corrugated and pre-printed linerboard, labels

and wrappers, folding cartons, liquid board and cans.
