Digital BW, The Print

Clayton Jones discusses black only printing. When I check the black 
ink only box of the 2200 I get a warning that black ink only is not 
suitable for photos. Has anyone played with this and found it to be 
so. Also, I am getting good results without metamerism by creating my 
own profile adopted from "Dr. Bob:

Brightness    0  (Dr. Bob uses +17)
Contrast      3
Saturation    0
Cyan          1
Magenta       1
Yellow       11
