Hello .. newbie here looking for general advice (links, books, concepts) for map design related to black and white maps. Also tips for maps originally designed in colour, but are printed in black and white on the standard office printer or even photocopied from the source document.
If you are working in pure black and white, I'm not sure of a good resource. If, however, you are using grayscale, I recommend checking out colorbrewer.org. It has some good recommendations on what K values to use. It is particularly helpful for thematic mapping.
Lastly, I would be happy to take a look at a draft. I have some experience working in grayscale and would be glad to offer any advice I can.

ColorBrewer did perceptive research to derive optimal colour palettes; it shows a maximum of 9 different greys. Howard T. Fisher's underappreciated 1982 book Mapping Information suggests that 5 or 6 is the limit for most people, but he was working in the era when we generally had to choose greyscale values in 5% increments. He developed a marvelous system of patterns that used a combination of density and orientation to symbolise 10 different values that could easily be identified:
Unfortunately, these were only marketed at the very end of the Letraset/Zip-A-Tone era of cut-and-stick film, so few people ever saw them. His patent (US Patent 4,148,507) should have expired by now, so I wish ESRI and/or Adobe would incorporate the concept.
