While I can sympathize with your frustration here, I think you're mistaken in thinking that somehow a developer that's "too strong" for film would give completely blank results. Think about it: if a developer is too strong (i.e., too active), you're going to get something like completely *black* film, not completely blank. Something else is happening here. (Sorry, don't know enough about photochemistry to be of any help.) Richard K.?

It's easily available everywhere - Ulan Bator to Ultima Thule. Finding it on the internet if you do not know the "magic word" is, of course, impossible. You might start with Agfa and ask them: http://www.agfa.com/en/gs/about_us/worldwide/index.jsp?countryId=108 Or Kodak - though they tend to be hopeless, kinda like their web site. http://graphics.kodak.com/US/ContactUs/default.htm Or contact a local offset printer and ask them. You would be looking for someone like this, only located in Italy. http://www.valleylitho.com/acatalog/Valley_Litho_Supply_Printing_Supplies_179.html -- Nicholas O.
