Using an Epson 2400 with Innova f-type gloss paper, I have tried a number of alternatives on the same B&W image. The Booksmart Studio profile, at least with my set-up, is extremely accurate. It provides excellent shadow detail and smooth tonal gradations, and is dead solid neutral in color. Using Epson's luster profile I get beautiful tonality, but the shadows go dark and lose detail. I also tried using Epson's advanced black & white mode with luster paper settings; this gives quite accurate color (I tend to use a slightly cool/purple tone) but the shadows again go dark. I got passable results tweaking the Epson black & white driver to go lighter, but not as good as simply printing a straight monochrome file to the Booksmart profile. Lastly, I tried using Photoshop's duotone mode. I get great results with this on my 7600 using cotton rag papers and matte black ink, but using both the Booksmart and Epson luster profiles the toning is exaggerated. Only the most subtle duotone ink choices look right on the Innova paper.
