My most dramatic example of this was during the Anthrax scare, when  
mail passing through certain mail centers was have certain undisclosed  
safety precautions applied to it. I received a fine art matte paper  
profiling target print (don't recall if it was HPR, but there was a  
lot of HPR being used at that time) from a customer, only to find it  
was a surprisingly bright yellow. I requested a replacement target be  
FedExed to me, and that one came through the expected white tone. I  
believe the process in question may have been intense UV light applied  
to kill Anthrax spores, though it could have been a gas of some type.
