OK, now I get it. If you only use, say three inks, you may not get 
that completely neutral (or other) tone that you now have. Varying 
amounts of ink on the paper will change the "color" of the tone too 
much. It's not completely about dotless prints (or filling in the 
dotted regions), but also about keeping those dotless prints at the 
same tone thoughout the entire scale from paper white to blackest 
black.
