The readings with the densitometer are as follows:

Indelible 100% K control = 1.76, 300 hour test strip = 1.71-;

      Fade (change in visual density) = 0.05+.

MIS VM 100% K control = 1.67, 300 hour test strip = 1.66;

      Fade (change in visual density) = 0.01.

So, at 300 hours, the Indelible is still slightly darker.  Whether this
would be true after another 300 hours is questionable.

You can look at the Jpeg in the files section and see the color.  It shows
up worst in the tones that are less than 100%.  However, the black ink would
be in shadows that would be light enough to see color.  So, the warming is a
problem.

In fact, warming is still a problem with the MIS FS-Neutral and VM-sepia.
As they age, the midtones don't warm much, but the MIS VM black does warm up
some.  As such, there is a bit of cross-over.  To really get to a
non-warming inkset, I need to figure out how to get rid of the black
warming, and that is a problem.  I've been able to slow it a bit, but the
density of the ink decreases, and the huge amount of pigment in the black is
hard to have much affect on with other inks.  That is why some "enhancement"
with black dye might be helpful in dealing with the warming issue.  I'll
just have to take a shot at it and see what happens.
