When I do this kind of work I typically print with a black boarder that's wider then the stretcher bar, then stretch the canvas onto the stretcher bars using a gallery wrap (staples in the back). I think they display just fine like this, especially in a gallery; clean, neat, no staples showing, nothing to distract from the image.
When I want to dress them up some more I use simple floater frames. The black of the gallery wrapped sides works great for this too -- they really make the print seem to float off the wall. Classy and elegant.
Note that a gallery wrap uses somewhat more canvas than a standard wrap (staples in the side). A 100 cm image on 44" canvas leaves you just under 12 cm of margin, so less then 6cm a side. Most framers are going to want more like 8-10 cm of margin to make a gallery wrap. So before you do this it might be wise to talk to the person doing the stretching and make sure your print size doesn't exceed what the framer is comfortable with.
