Digital BW, The Print

I think there's no such thing in the sense that RGB is not a colour model
per se.  You would have to define which RGB space.  The numbers for R, G and
B, respectively, for a given CIELab colour will be different for each RGB
space (Adobe RGB, ProPhoto RGB etc) and in fact there may not be an RGB
number for many CIELab colours - because of gamut limitations.
