The word "color" is everywhere:  ICC -- International Color Consortium, Color
Management, Colorsync, ...  I'm not about to try to coin new names.

Grayscale profiles are not something I defined -- they are defined in the ICC 
specification and implemented in the "Color Management" software packages 
I'm aware of.  They are however missing from most of the profile making 
software packages.  Grayscale profiles are the only thing that will work with 
for instance the Epson ABW driver.  In other words, if you want to use the ABW
Epson driver, and you want screen to print matching without trial and error, and 
softproofing the only "Color Management" solution is to use grayscale ICC profiles.
