Exactly right.  And reason is that using a single ink color just 
plain doesn't give the dithering algorithm enough to work with.

Look, I don't know how many other people here have actually written 
inkjet drivers, but that's what I used to do for a living so I know 
whereof I speak.  I've written both stochastic and ordered dithering 
algorithms and one thing is certain:  ALL dithering algorithms 
represent a tradeoff between spatial and tonal (or color) 
resolution.   To gain one you lose the other.
