Not in "hextone" Piezo or FS inksets designed for the Piezo driver.

For hextone VM there is black and 3 different grays, and two different
densities of the toner -- so it is a true hextone (true B&W quad also).

The traditional MIS hextone set used 6 tones also.

I've never done my own analysis of the Piezo 6-ink smoothness.  I think I've
heard that the 1160 is just as good, however.  The point is, I guess, that
you just don't need 6 inks for a visually smooth B&W print.  In fact, 3 inks
do an amazingly good job.  It was Jon Cone's statements to this effect that
led me to, first, test it (3 was fine) and, second, to realize that we had
an extra position for a toner ink that could control the print tone.
