For some time I've been printing on Canson Rag Photographique paper and have been very happy with the generic profile. However now I've got some black&white photos and they just don't look good enough. On the generic profile dark black seem to have green cast and greys look a bit red. So I've created a custom profile with a profile maker. And well... it is better but I think epson 9900 can do better than that on this paper. Color cast on greys is gone but I the black... still seem a bit undersatured. Basically my question boils down to - how can I move black point inside ICC profile and will it help (at least in theory:)
There was a very good article on LuminousLandscape about increasing color density in the driver and than creating a profile but first I would like to see if I can do better without changing paper settings.
