Hi Elias,
We know of this problem before. The reason why there are some
stains on
the paper is because Kentmere removed the cadmium that it originally
came with. Basically, this changed the whole composition of the
emulsion. A solution to correct this problem is to change developer
and
use distilled water. The less this paper soaks in chemicals, the
better
it will be for the paper also. If you are using a metol based
developer,
try switching to a phenidone base developer or vice versa. Water also
plays a part in this chemical reaction that's why distilled water is
suggested.
Europe is trying to ban cadmium because it is a known carcinogenic.
Manufacturers, not only in photography, but also in paints and others
reformulated their ingredients to remove cadmium.
Hope this clears up everything. Let us know if you need more
information
or have any more questions.

Are you at Freestyle aware of the problems people are having
printing on
Kentona? I've uploaded two prints onto Flickr to show the staining
that
is happening. http://www.flickr.com/photos/elroustom/3082943772/
I've found a photo.net thread where others are seeing the same thing.
Maybe between you and Kentmere you can figure it out. Unfortunately I
have about 12 sheets left, and they're useless...
Thanks,
Elias
