@Del - Funny stuff! I didn't think of that. I was thinking more of a "Timmy the Tooth" kind of thing.

@Joe - Not a clue! I assume books are all printed with offset printing. I have no idea if they can reproduce grayscale, or would be dithered B&W. I'm working on the latter assumption, but that could be wrong. Maybe a printer, publisher or author would know the answer!
