Stretching a canvas and displaying it unframed is the obvious way to display a canvas print, but hardly the most durable. After all, without the protection of glass, it is subject not only to more light, but to atmospheric pollutants (fumes from cooking, smoke, ozone) and to dust and dirt, and, without a rigid backboard, constant flexing and bending of the print (in response to changes in temperate and humidity) could lead to damage.
What is the best way of displaying a large, unstretched canvas? The way I see it, there are a number of options:
1. Tapestry mount. This removes the problem of canvas stretching over time, but is just as unprotected as a stretched canvas. Also, IMO tapestry mounts look wrong for photographic prints...
2. Frame and mat - just like a paper print. This is obviously great protection, but would a larger print be too saggy and wavy to make an attractive matted print? Would a hinge mount across the entire top of the print solve this problem?
3. Mount it to a rigid backing, then frame/mat it. For archival purposes, you'd need to use something like Dibond, anodised aluminium or titanium, or acid-free, buffered matboard as the backing, but what about the glue? Something like Glamour 2 is acid-free, durable and suitable for mounting prints to a mount board, but hardly reversible. Rabbit-skin glue is hygroscopic, which doesn't suit canvas. PVA glue is acidic. Lascaux 360 or Lascaux 303HV is reversible with solvents and often used for fine art, but how would these solvents interact with an aqueous inkjet canvas sprayed with Timeless or Eco Print Shield?
What is the best way to do it in order to maximise the protection of the print, while displaying it in an attractive manner (i.e. not full of bends and sagging parts due to insufficient support)?
