Digital BW, The Print

David, So true, but I think for the average guys and gals trying to tackle
this, simple RGB and HSB values might bring it into focus faster; both are
readily available within PS. As not everyone has or will have a colormeter
but they most likely have an image editing software that can give them these
simple values.

Thats terminology from another era... "inkjetters" as you call them need to 
know when an RGB value is two points too red... "cc's of Magenta" have
little 
meaning in the digital world. Now we live in RGB, and use L*a*b* as a
universal 
color standard, with differences measured in Delta-Es. This red is 5 
delta-E97 from that red, this black is 2 L* lighter than that black, this
paper white 
measures at -6 b*, so it must be artificially whitened. Those are the color 
distinctions of the digital imaging world. Please don't send them back to
learn 
Latin and Greek!
