I think I see what you are doing. Similar setups could be put together
with some creativity with SP, but the main tool allowing your idea is
the QTR blending (I think?).
But I wonder- given the large amount of overlap that must occur with 7
inks (which Roy also mentiones) the K7s with QTR may be doing
something actually similar.
Am I wrong in deducing that a main advantge of your idea is making use
of as many nozzles as possible, and the resulting complex weave?
