If inksets, paper, printers, and spectros were all exactly uniform, it would
make no difference if you re-linearized the profile.  Of course, none of
these things are perfect, but most find that they are within acceptable
tolerances.  I might add that I was very pleasantly surprised when I
measured the draw down values of the last batch of MIS Eboni-6 I received.

Also, what's the "T" designation in EB6-EpsHPn-T?

 On profiles with the "T" added I took half of the inks and put them into a
"toner" channel.  This way there are more overlaps.  For example, in the
lightest parts of the print, instead of just the 2% Eb6-Y firing, both it
and the Eb6-LM (6%) are operating.  With the 1400 both of these inks are
dotless.  The downside of this if you want the most neutral print is that
the change in Lab B goes from 1.5 for the standard profile to 2.3 for the
"T" profile.  See the Notes tab in the profiles.

Hope this helps.
