This aspect of digital photography is probably the most migraine headache producing issue around. I dry mount (I have a press) the inkjet prints after a couple of days of letting them dry. You have to test the temperature/time issue although these are papers are not resin coated so they seem to be less temp sensitive than some of the true photographic papers. Anyway, I've used 225 deg for 2 minutes on Kodak inkjet paper and it's happy.
If you send your files out to a lab, then you need to know what kind of paper they're using. The lab that I use (autumncolor.com) uses resin coated paper so either they mount the print or I do. If I do, I used 3M Photo Mount adhesive. I mount flush, that is if the print is 8x10, so is the mount board. Therefore I spray the mount board, then align the print and lay it down. This would be trickier if you float mount (position the print a set distance from the mounting board's borders.
The reason I flush mount is that my framing is a "california floater". I build a frame the same size as the mounted print then glue the mounted print to the frame. This positions the framed picture about 1.5 inches from the wall. It's a style I've always liked and have used for years.
The big bugaboo here seems to be print fading. There's a lot of info on the forum about it, but it does appear to be a problem. I'm holding off buying a larger inkjet printer (Canon i9900) because of this issue.
Ironically I've had 35mm prints on the walls for over 3 decades without noticeable fading, but I don't place mounted prints in direct sunlight. If I have a really good pic, I'll send it up to Autumncolor (Worcester Mass) and they'll print it using their LightJet printer. This printer uses lasers and photo print paper (Fuji Archival). I normally let them do the mounting (cold mounting so they're using some sort of spray adhesive). Anyway the prints come back looking excellent and they're on photo paper so ink fading isn't a problem.
I'm still doing 8x10s here, but I'm very careful where they end up in the house. I'm also looking into laminating the prints, but that means that like it or not, they'll be "glossy" (I think... new area for me so there may well be matte laminations out there).
Hope this helps.
