My concern is about the proper way to back a framed stretched canvas. I have
been told by other framers that the canvas needed to be vented in the back so to
prevent trapped moisture. One framer went as far as papering only the frame and
stretcher bars, then cutting a large opening in the back therefore exposing the
entire backside of the canvas. This may also expose the canvas to possible
dents and tears.
Hoverver Michaels' latest Production Certification manual suggests that we "cover the
back of the stretcher with a rigid, acid-free backing at least as thick as 4-ply
ragboard. Screw the backing to the stretcher bars. ...use a dust cover to
conceal the mechanics of the framing process, although not necessary." It saids
nothing about cutting vents or using screens to keep insects out.
So are we screwing up by exposing the backside of a painting?
