It's a characteristics of the inks. At the right side of graph is the blackest
color that is possible. But the blackest is by no means maximum black ink. The
most black color is achieved by the mix of inks taking into account the TIL.
The absorption by spectrum of color inks and black ink are multiplies. The
black ink alone not so black as the mix. Moreover, taking in account the
reflection power of inks, increasing of black in the blackest formula leads to
decreasing blackness. So the black can't reach upper right corner at certain
TILs. Yo can play with TIL and may be You get black at upper right corner.

Now that I learnt something more, getting the same plots as yours, I'm still
wondering: why it seems impossible to push the black curve end point toward
the upper right coordinates limit?
Don't get me wrong, I'm not saying that Argyll is supposed to behave exactly
as another CMS but I just want to learn as much and as well as possible from
your experience.
Thanks
Fabrizio
