@rdeloe1: "Unfortunately, kludgy approaches like this suffer from the problem of reproducibility across media… and mine is no exception. In the end the only thing that matters to me is that I can get reproducible high quality results for specific ink and paper combinations" Precision and predictability and reproducibility will require an ICC for each combination produced by a measuring device. I find it works pretty well. You then have the choice of using Roy's preferred workflow, of converting to the ICC, or Jon Cone's, of using the ICC only for "preserve numbers" soft proofing. Using generic ICCs will get you part of the way, but as you're discovering, they're a variable approximation. If you can manage to live with that, well done!

@ Larry: You need to realise that when you "use LR for proofing only using Roy's RGB ICC", this assumes that you're going to convert to that profile for printing, which is what rdeloe1 seems to be doing. But as I understand it, you're not. You're just printing the image as is without any conversion, and QTRGui won't do any conversion, so what you're soft-proofing does not reflect what you're actually printing. You either have to do the conversion to the ICC for the soft-proof to be valid, or to use "preserve numbers" which soft-proofs what happens if you print the image without doing the conversion. As we've discussed, you can't do "preserve numbers" in LR.
