Digital BW, The Print

Hmm, Tyler, I see your point.  Reflectance depends only on the the 
concentration of the pigment per unit area of paper.  So, the finer 
the dither, the less the local concentration of pigment at each 
droplet.  If the dither is coarse that particular droplet will be 
more concentrated.

Regards.
