jdef, I forgot to mention one thing about POP that is not included in the book I recommended you. If you do decide to use the paper, when you print put a thin piece of mylar (1 mil) in between the paper and the negative. The paper will stain the negative after a few pasess. I am unsure about why, and I am not knowledegable enough to tell you the reason, but a very experienced person gave me this advice and he sure was correct. I of course knew better and tried it without the barrier first.....

Since this is also a silver chloride paper you will need a UV source, the sun will do!. Actually the only difference to Azo is that it does not come in grades and of course the obvious it is POP. For my taste this paper has much more posibilities than azo since the gold, pt, etc toners produce an incredible array of colors.
