Digital BW, The Print

Give yourself some credit Carl, even with Dan's old work few if any
have carried it forward. It takes some creative thinking to come up
with this stuff. Your thought about L values seems right to me as
well, but then there is always that final conversion to gray, and then
WHICH gray? But if your profile is previewing properly to your prints,
that's all that matters and the converions must be valid. I'm in the
process of doing the same thing for StudioPrint here, and this
approach can be used to preview literally any type of printing with
any kind of output system, any of your ink mixes on any paper.
Paper white and ink black are useful as well.
Good to know Match doesn't choke on these values so far from the
expected color, Profiler Pro works as well.
