In the case of matte/rag papers, I've found I get better results by keeping
the image in gray-lab and printing with Gamma slider set to +4. Converting
to the ICC profile blocks up the shadows too much.

Results might be different for different papers, I haven't tested this
approach with semigloss/luster papers yet.
