I've never heard of anyone recovering this type of fading-. Diazos
were often used as proof copies because of this very property (they
go away with time). I've also got a pile of old FAXes done on
thermal FAX paper. Also unreadable.
Still, if anyone has any solid documentation on how to go about this,
I"m listening.
