Digital BW, The Print

If you have a monotone RGB file you can still convert to a greyscale output
ICC profile for printing.  You don't need an "RGB monotone ICC profile".
The only issue arises if your printer driver/RIP requires an RGB rather than
single channel image file.  The I suspect you could convert to a greyscale
ICC profile and then assign Adobe RGB (and so keep the file numbers the
same) and then use that for printing through a non-colour-managed driver.
