This seems to me a rather convoluted way to print with pthalo, but
whatever works for you....

I didn't see Judy's original post quoted below. I would agree with her
that it would be remarkable to see a one-coat made with very dark heavy
pigment that printed 8 steps, But I would disagree with her statement
that experienced printers can't expect more than 6 or 7 steps even with
a lighter pigment/mix; I routinely print 8 to 10 steps when I'm
printing the midtones-highlights layer of a (monochrome) image, or one
of the layers of a tricolor. But Judy and Loris, I think, are talking
apples and oranges. Judy's talking about a one-coat gum that is
printed with a very dark-valued pigment; Loris is talking about
tricolor, where the darkest values are created by overlaying three
layers, none of which are as dark as the darkest tones in the combined
image.
