Digital BW, The Print

For the 2nd conversion from greyscale to RGB to prepare for printing:
It may be implied, but also make sure that you are not in your editing 
 greyscale space (the greyscale space you use to get your monitor to 
match print, 20%dot gain, more likely a custom dot gain curve, etc), 
and make sure that you are in the appropiate RGB space Paul's calls 
out for your printer/OS combo. In most cases this is conversion from 
the grayscale space of "gamma 2.2" to either "sRGB" or "Adobe98".

But I question if the first conversion from RGB to greyscale would not 
comb out your image data and cause posterization even before you had a 
chance to work on it. Have to be checked anyway. Might be okay if you 
were in 16 bit mode.
