> How do we expect someone will be curious enough or have right gear to read these sheets? ~.1 micron. Pretty small feature size. Typical letters might be 30 by 15 dots in a 10pt font with their 150DPI assumption. But it's not -that- exotic. A cheap compound optical microscope might do .4 micron, resulting in letters being 8 times and 4 times the spatial resolution. This is in the range where things are slightly annoying in fuzziness but still easily legible. My crappy LCD microscope for my classroom cost about $50 and has a resolution of roughly 1 micron. It could probably read, with difficulty, 12pt text.
