I believe this might be due to sharpening issues and noise and fuzziness due to compression in the photograph/scanning of the Imus map. When scanning/photographing text one must sharpen more aggressively than usual, and also use higher quality/lossless compression. It seems the author of those digital pictures is not skilled enough as to faithfully reproduce paper documents digitally.
