My message may not be clear enough. The BO option is the usual 
output for greyscale images in RIPs. I'm advocating an extra 
choice in the use of Kkk inks instead (+ toning for 
neutrality, sepia, cool). That would allow good B&W printing 
in a RIP + the combination of good B&W printing and color 
printing. Another possibility would be to direct greyscale to 
an RGB flow as well but give it another profile/paper setting 
treatment with total black generation from 100-0% and the 
profile more directed to neutrality.
