There is a fade test that compares Indelible to MIS FS-K and Gen4-K in the
Files section of this forum.

Follow the path: Files > Ink Sets > MIS.

This is just a 100 hour test to verify that the sample I was given was the
true stuff - it was.  Some could not beleive after all the hype that
Indelible black appeared to be a hybrid dye-pigment ink that faded and
warmed substantially more than FS-K - it does.

You can download the image and measure the extent of fading and warming with
the Photoshop eyedropper.

The posted results are consistent with a longer 300 hour fade test that is
not posted.

On EAM paper, Gen4 is darker than Indelible black, and Indelible is darker
than FS-K.  However, after 300 hours in the fader, MIS FS-K and Indelible
are about the same density.  300 hours is about how long it takes most
inksets to go through their initial warming phase.

Except for the UltraChrome black in a very initial test, all the black inks
that I have tested that are darker on EAM than FS-K fade and warm more.  As
the dyes fade away, it appears you end up -- at some point -- with a brown
black that is not darker, and ultimately probably lighter, than FS-K.  The
blacker the ink, the more apparent dye, and the worse the fading/warming.
