Hi Tyler,

Then you're missing the point of dithering.  You can represent ANY number of
tones by dithering, it's simply the area that it takes to do so...you simply
need to stand further away ;-)  Increasing the number of inks simply
decreases the area needed.  It can also be considered "resolution"...

So, help me out here...  Make a 256 Z pattern, and see if you can
distinguish 256 Zs...  What do you think of doing that???
