As for injet printed decals, you can obtain Archival inks at a slightly higher price. They will not fade out.
FWIW

Inkjets are OK, I do have a few issues with the color rendering with most inkjets. Blues tend to the purplish side and a few others just don't render well on inkjets. But as foose mentioned if your applying to a light colored model they can do a good enough job.
I've had no fade problems with Durabrite epson inks on Micro-Marks papers.
Most of the "Cheapy" on-line papers work ok as well, you just waste alot in crimped, torn or damaged in shippment sheets. After several horrible experiences with Bel papers, I personally will never buy from them again. Some folks have had better luck? On the other hand, every single sheet of every shipment i've had from Micro-Marks have been 100% perfect, not even a dogearred corner anywhere

sometimes that couple extra pennies per sheet is well worth it lack of headaches IMHO.
It's also possible to make your own decal strips using water based paper packing tape (Butcher Paper Tape) and plain old spray UV clears as a base. That's how we made decals back in the B.C.... "Before Computers" LOL!!! Hard to remember that only a few short decades ago all graphics and lettering had to be Hand done. Things are so much easier now.
