Mondrian Hall (now Unisource) had a DMPSV-G Glossy Adhesive Vinyl (5 mil) but it was a little over $1 per sq/ft.
Other options is to just use a gloss photo
paper and add adhesive to the back although the adhesive may add enough to the cost to be back at the above. If you have to laminate it then use a matte vinyl if you can get. Not 100% sure on the ultrachrome inks though.
