Digital BW, The Print

David, That is how they stack up to the ABW in terms of ink usage, not to
one another; i.e. a neutral ABW setting and a neutral profile not just
printing a grayscale image with a profile intended for color printing.

 

Toners within an ink set like the Piezotones selenium, and sepia tones that
may or may not be single pigment solutions. I don't know. I didn't mean
toners as in using a color pigment like LM, LC, etc.

How they stack up in other respects might indeed be interesting, but there 
would not be any meaning to looking at the ink usages between them; all an
RGB 
profile can do is ask for R,G, and B. It can't tell the driver how to define

channel splits, or ask it to eliminate components.

Toners included in the neutral inks are still toners. It doesn't much matter

if that yellow ink is mixed into a gray ink or not, it will still cause the 
same degree of illuminant metamerism, or the same degree of fading, as the
case 
may be, ; plus it will add the highly undesirable situation of mixed inks
with 
differential settling and differential moving in the lines. Inks built out
of 
pure, single tone pigments are a much better deal for B&W inksets than ones 
with colored toners added. 

If you are going to add color, adding it directly from a color cart offers 
the advantages of knowing just how much you're going to get, and allowing
you to 
choose how much you want. I'd certainly love to see the next generation of 
Epson drivers reduce the percentage on color inks for neutrals even further,
to 
minimize the issue at even a theoretical level.
