For those of you who are questioning my integrity and honesty over this statement that I made, "I know exactly where and how this piece of film was coated It was sent to me in confidence for diagnosis with all added information needed to respond."
I would like to respond in public.
First: The agreement has expired! It was quite a few years ago that this took place. I would never divulge a confidential piece of information that was covered by an existing agreement (see below) and this goes for Kodak information as well.
Second: I can say that one or both of these companies has vanished so the point is quite moot.
Third: Except for the coating example the rest of the information is still disguised for the purpose of protecting both companies.
Fourth: I viewed the posting of this as being valuable to the discussion and to the APUG membership.
Fifth: I've posted this information before without any comment from readers. And, pretty much in the same context as here. The agreement had lapsed back then as well.
So yes, you can trust me and yes, I am being honest about these posts. Lets not go overboard people. And yes, this is a real example. I have the sheet of film in a roll here beside me. And, what prompted my original post several years ago was due to the fact that people had posted similar examples from more than one company. So, this type of problem can be endemiic in the industry if the machines develop wear and the pumps and drive motors develop minor tuning problems.
Kodak takes such fine care of their machines that a friend told me that Kodak engineers once observed this "coating noise" problem and could not determine the source. Someone scanned it with an optical scanner to determine the frequency and just happened to play it back through an audio system. They could hear the sounds of the voices of the coaters! So, not only are Kodak products coated in the dark, now they are coated in silence.
