Likewise, paper company reps have told me that our inkjet papers are sometimes coated on both sides, not for printing but because the manufacturer found too much paper curl when only one side was coated.
Back to my large canvas mounting issue, in trying to find a light weight solution for a large display that needs to be easy to hang on a wall, a lightweight composite structure, coated on both sides, has appeal to me. FWIW, see https://en.wikipedia.org/wiki/Sandwich-structured_composite .

Hi both of you
Being a photographer (an a woodworker too) this "tacking" question relates a lot whit what we call "surface tension". Any substrate used will warp if only one side is coated; using a 3'; x 6' (and 1 1/4" thick) wood panel, if only one side is glued, let's say with Arborite, you will see the warping. It can takes a week or a year depending on the conditions but… it will warp.If you want to test some substrate. I would consider gluing a scrap piece of the same material on the back of the mounting board to alleviate the effect. That's why you see furniture (made with Arborite for example) having a "backside" glued with a similar material to stop the warping.Good luckJacques CaronLe 2016-09-05 à 10:55, "Paul Roark roark.paul@...
