Flexography and gravure together account for a packaging print market worth $358.5bn, according to a Smithers market study that maps both processes over the next five years. The number matters because the two technologies sit at opposite ends of the run-length spectrum, and the split between them keeps moving.
How the two processes differ
Flexo prints from a flexible relief plate: the image sits on raised surfaces that pick up ink and transfer it to the substrate. The plate is photopolymer, exposed and washed out like a printing plate for letterpress, then mounted on a cylinder. An anilox roll meters the ink, a hard ceramic cylinder engraved with millions of tiny cells that deliver a controlled film thickness to the plate. Flexo runs on almost any substrate, from film and foil to paper and corrugated board, which makes it the default for labels, flexible packaging and folding cartons.
