I'm interested in the comments about storing RA-4 paper at room temperature. I've just started with RA-4 printing, and the box I've got (Fuji type P III), as well as everything I've read in books, says the paper must be refrigerated. Is this "must" overblown, or are there paper-to-paper differences and I just happened to get one that requires refrigeration? It'd be a bit more convenient if I didn't have to refrigerate the stuff I expect to use within a few months, but I'll refrigerate it if it'll provide consistency benefits.
