Digital BW, The Print

Roy- Outstanding! This is probably obvious, but I want to doublecheck
with you. The values below look like RGB numbers, which suprises me a
tad for a profiling reference file, rather than LAB. So RGB values are
what Match wants to see?
Also, can I assume from your work here that I can create my own
targets and ref files as you have done? I'd like more than 21 patches,
I find these profiles don't predict some areas well, like 95 to 100%,
and more samples might help.
You guys are smokin' now!
