Hey Ben,
We've never run latex so I don't have much to compare to, but the prints are very scratch resistant off the UCJV using LUS 170 inks. I was worried about that at first but the ink is far more durable than I expected. I've been meaning to wrap one of our walls w/ unlaminated prints from the Mimaki and still hope to soon.
Let me know if you want me to do any testing for you.
Cheers,
Pat
