Dear Guys,

An interesting debate, I have spoken to our production people we do not produce any developer incorporated paper emulsion, in relation to a component chemical addition or a 'preservative' that could give a positive test, would you argue with PE ?....lets put it this way, we would not.
Our papers do 'rest' after coating for a period of not less than 7 days before finishing.
