David, I know some people who have waste their time trying to outperform SOME canned profiles. HP comes to mind. It's a complicated issue to be sure. It depends on a lot of factors. With some printers and some media and some drivers, I've seen canned profiles way outperform custom profiling. HP has really done some profiles right. Beats the shit of all my tools and instruments...

I don't think what I am writing is part of your issue. I use custom .icc profiles I create on my own. I refuse to use canned profiles! Cheers David B. Miller
