Curiosity question... I know that the drivers are usually RGB but
internally, the printer usually speaks in terms of CMYK BUT... you say there
is no red, green, or blue colorant yet many printers (mine included)
specifically have RGB inks. My printers use the following inks: Matte Black,
Black, Gray, Photo Gray, Blue, Cyan, Photo Cyan, Magenta, Photo Magenta,
Green, Yellow, and Red. So there's 12 channels there and of the blacks/grays
only 3 of 4 are used at any one time. If you break it down though you have 7
colors, CMYKRGB. I'm curious to know why the red, green, and blue inks
 wouldn't be counted as colorants?
