QR code subtleties

The good men and women at Poster Session are on the ball. Here, they detail a whole bunch of issues with printing QR codes on posters that are... subtle.

An even more detailed analysis can be found here. As usual for posters, the solution is to make it big! (Also, testing the code at final printed size is probably a smart idea.)
