The reason why there are some stains onthe paper is because Kentmere removed the cadmium that it originally came with. Basically, this changed the whole composition of theemulsion. 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 informationor have any more questions. Oliver Tan Retail Asst.

I've uploaded two prints onto Flickr to show the staining thatis 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...
