[QUOTE]\nAssuming that errors can occour, this is not the case. I've prepared\nD-85 and immediately put into the tank, so I've developed film, not\nfixed. The fact is that everything is disappeared form film, numbers\nof pictures and trade mark too. Surely this is an extremely strong\ndeveloper, I'm thinking to try again it but diluited ten times.\n[/QUOTE]\nIt seems to me that if you are sure you used the solution for D-85\nthat you prepared, and get blank without even the edge numbers and\ntrademarks, before you even fixed the film, then the developer solution\nmust have been prepared incorrectly or the chemicals you used may\nhave been mislabelled. Assuming you are using 35mm film.\n\nIn my experience, the sheet litho film (Kodak 2553, IIRC) not only has\nno edge notches, making printing on the correct side something of an\nartistic experience, but also it has no edge markings.\n\nDiluting the developper 10x will not help you.
