Just printed a sign onto Metamark MD5. I use this for other products and it seems fine. This sign is around A2 size. I went to mount it onto some correx type material and it was a nightmare. Creasing before I'd got it anywhere near the board!

Done this plenty of times over the years but obviosuly not with this material. I assume an air escape material would be better at this size? Or maybe just cut vinyl ;-)
