Whats next? Some sort of physical DRM for printed copies?
If you dig back into storage and find some of those early 1st edition dungeon crawls, you'll find that they were printed in a lightish blue ink.
Mimeograph machines and black and white copiers at the time (I don't think color copiers were commercially available yet) had real trouble with that color ink.
This was intentional. It was, in effect, DRM.
