Printing of DH begins in Germany

The Mirror is reporting today that initial printing of Harry Potter and the Deathly Hallows has begun at a GGP print factory in the small town of Poessneck, Germany. Reportedly, staff at the factory are searched when entering and leaving the factory each day. Furthermore, they are forced to work in "total darkness" to prevent them from reading the book. While we already know that security is stricter for this book, this seems to be a rather outlandish measure (and, well, The Mirror is a tabloid).
