Super 8mm Films...

I have a few faded digests. As I usually buy some on eBay I can say it's hard to find one that isn't a little faded.

What type of film are they printed to and why does it happen to that films and not to the home movies we film with our cameras?

I'm sorry if you'll feel offended Tim, but the only way I know would be digital color correction.

Gimme a K! Gimme 40 of'em! Bingo, 40 times as long archivability (at least)!

Kodak introduced "low fade" cyan dye technology in print stock (the film used for 35mm prints and your "digests") in 1979:

You can read all about it on the Kodak website:

1979

* EASTMAN Color LF Print film, 7378. Improved cyan dye post processing keeping. Process ECP. Markedly improved cyan dye dark-keeping stability. Discontinued January, 1982.
* EASTMAN Color LFSP film, 7379. Same as 7378 except for Process ECP-2. Markedly improved cyan dye dark-keeping stability.1 Discontinued 1983.

1982

* EASTMAN Color Print film, 7/5384 Improved cyan dye dark keeping and red sensitivity to process variations. Process ECP-2A. Replaced 7/5381, 7/5383, 7378, 7379. In SMPTE Journal December 1982 and BKSTS Journal August 1983.

You can greatly slow the reaction that causes dye fading by storing your films properly, in accordance with SMPTE Recommended Practice RP131.
