It was nice to see a mention of Robert Ulichney. His 1987 book "Digital Halftoning" covers most of the ground that this blog post does, plus more.



I saw this book mentioned a couple of times during my research. I guess I should read it.


Donald Knuth also has two nice chapters in "Digital Typography".


I might have to look that up. It's hard for me to imagine what dithering and typography would have in common, other than they might both be used to produce a book.


IIRC he created a special font for half-toning images.
