This question has been burning in my head since November 8. How do they print notes without the employees at the press knowing that's being printed. Are they all awesomely nationalistic and don't leak news? Googling on the subject got me nothing. This lady claims that at a security press, the workers don't even know what's being printed. That is awesomesauce technology. And I say that as someone who's hung out at printing presses since childhood. Everything keeps breaking at a press.
