That is true that they are not emulsion based and are printed, and will not fade the same way that other film types will, but they still fade. Just the way a print in a magazine can fade over time. Dyes are still chemicals and react to heat and light, both of which are there in extremes in carbon arc and other forms of 35mm projection.

For our purposes the fade will be so small as not to be an issue.

Oh, for sure. If the Book of Kells was displayed in a window for the last 500 years, it would be badly faded, no doubt. The same would happen if IB prints were exposed to sunlight or fluorescent bulbs, but since they're mostly sealed up in dark cans, they're protected from most of the bad stuff.

Of course, the Kodak stock has all those nasty chemicals stuck to it, altering and changing away, as chemicals tend to do.

Exactly, as long as the print has been stored well, it should look lovely, and the shots Mike has posted so far look like it has.
