The local boutique hotel purchased 6 large, stretched digital prints on canvas. They are float framed. The canvas is far too light weight for the size, 45 x 55. They are only a few months old and they are all rippling. Some worse than others. Sorry didn't take pics. Should I drymount them, build a 1x1 cradle, to make it like it's stretched, to re-use the float frames? I spoke to the artist, who has no knowledge of what they are printed on, or of what the solution would be. They're sold and no longer his concern. I'd appreciate any opinions from those who may have drymounted such carpy things. Send them somewhere else is a pleasing thought. Thank you. My cost estimate is $1300. each.
