Digital BW, The Print

This is an idea I've been wondering about, but since I don't do BO
printing or use QTR here, or the printers/inks you guys are using, I
wouldn't have the need or opportunity to try it.
This assumes you have a printer with a K and a Light K ink of some
kind, and QTR.

Most of the systems with 2 K inks are doing a transition of some kind
from the light K to the K, then depending on inkset possibly adding
other inks for tint.
For a BO approach, why not try running the two Ks in parallel instead
of series? This would require a special driver like QTR, OPM, or a
RIP, and no doubt need linearization or a gamma correction curve since
it would print dark.
But the possible benefits are that since there are no very light K
inks are present you would still get the kind of loose dither you like
that lets some paper white through, but it would also be a more
complex, random, and possibly more photographic dither since it would
still be running both K inks all the way up the scale.
Just an idea.
