Yes, the Indelible black is black.  It's density is between the MIS VM and
Gen Enhance black.

The steps are still even (just brown -- see the jpeg I put in the Files
section), but the test strips were black ink only.   So, it doesn't answer
the question about how they would look in the context of a full quad inkset.

I must say, however, that your observation is not lost on me.  I'm
considering trying to make an "enhanced" black that does not warm up.  If I
could control the warming, I'd be willing to take some more fading, IF it
would work in the context of a full quad.  With the MIS FS-neutral -- which
inks are also used in the MIS-VM-Sepia -- I've gotten the warming to near
zero in the midtones, but I have not touched the black yet.  So, ...

I have posted the results of a fade test in the Files section of this forum.

The short summary is that the Indelible black ink test strip faded and
warm-shifted much more than the comparison MIS VM/FS black ink test strip.
(A description of the procedures and detailed results are below.)
