I actually have been using a different density for each ink; In the
end it just got too tedious keeping track & refilling, etc., so I
averaged out each pair, and it worked just as well... the KISS
principle in action.

The biggest problem I had with this was maintaining good contrast in
the mid-range; too much ink and the midtones posterize, too little
and the highlights suffer. Making the yellow higher density seems to
give better highlight detail without filling in the mid tones.

I started by doing something very similar to this with the VM inks;
It got to be too much nuisance to color-balnce those inks however,
and I was not comfortable with the stability of the toners- my own
informal fade tests indicated that they color-shifted quicker than a
pure black inkset, though the difference probably wasn't that
significant

I suspect Cone has set up his profiling system on his existing ink
arrangement, whatever that is. After all, he can't stop producing
those inks yet, so why come up with a whole new set of

Thanks-and I will participate, as soon as I can get away from
refilling carts-it's just too much nuisance!
