It lasts a long time, at least as well as a hotstamp. There were a bunch of skull-printed aviars floating around for a while, and every now and then I see one, still looks fine. This isn't new technology, but it must be radically more expensive than hotstamping else I would expect to see these regularly. Maybe it takes a lot of time as well?
edit: I realized, 2 seconds after posting, that the printer won't catch the sunlight like a foil hotstamp will. Long-live the foil, just don't burn it in (Discraft, talking to you, hint hint).
