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!
