I wanted to add another option for displaying prints that is better suited to frequently changed, temporarily displayed prints. I use check order racks which are also known as menu slide racks to display a selection of prints on my walls. This is a great way to put up a print for review or even relatively long term display. It works best with prints that have been printed on sheets. Some roll papers seem to have a semi-permanent curl to them that no amount of flattening really removes. These "racks" are essentially an aluminium slot filled with marbles. You slide the print up in between the back of the rack and the line of marbles and friction and gravity holds it securely in place. Most papers don't show any marking from this process. I am attaching an image of one of the walls I have installed these racks on.
I have tried two brands, San Jamar and Tablecraft. San Jamar has a higher level of finish and a lower profile but the space to actually "hang" prints is 3" less than the actual length of the rack. The San Jamar racks are easily cut down with a hacksaw with no aesthetic degradation. The Tablecraft racks are somewhat cheaper looking and are about 3/16" deeper but the end caps only consume 1/2" on each end although there is a screw head about 7/8" from the end. If you use a screw with a low profile head it only interferes slightly with the paper so a 24" Tablecraft rack should display a 17x22" sheet in landscape orientation. Cutting down the Tablecraft rack is possible but it will be less aesthetically pleasing. Tablecraft offers a 72" rack while San Jamar's longest is 60". The racks in the attached photo are San Jamar 60" racks cut down to 58".
Amazon has some smaller sizes of the San Jamar racks and
www.katom.com has a wide arrange of sizes with very good pricing and shipping policies.
I have also tried mounting photos to self-adhesive gator and gluing mounting blocks on the back. That gives a great display but I have found it to be quite a bit more finicky and time consuming than it sounds.
http://www.artgrafix.net is where I bought my self-adhesive gator but their sizes weren't exact and the seem to have stopped offering 17x22" precut gator which is the main reason I used them.
