We don't get that many used prints but we have been getting a lot of them using masking tape at the joint of the header and the film. I hate that because masking tape leaves residue on the film. I try to clean them up so they are in better shape for the next guy than they were when I got them.

I still use a decently generous amount of tape. I never keep the existing tape when a used print comes in. And I still use a pull tab. The pictures below should demonstrate which side the tab needs to be on. I used one of the shorter reels from Inception for this demonstration:

For this demonstration, the soundtrack is away from you, even though you cannot see it. That means the reel is properly wound emulsion-out. Those who do not wind emulsion-out are retards unless they have a very specific reason for that specific print.
 -
The pull tab is on the left. Look how inviting it is. No picking at the base of the tape will be needed to remove it.

 -
OK I'm going to try it. Let's see, I just grab the tab and start to pull!

 -
Oh wow, this is easy!

 -
I'm almost done and none of the film is coming off with the tape. How considerate of the person who applied it.

 -
I did it! I'm done! You can see where the film starts and it goes to the left, so that is the side the pull tab must be on. PROTIP: This even works for taping the tail when you move prints!

If only everyone would apply tape in the fashion of Joe's pictures above, life would be much better.

Its sad though that Joe had to point out the winding direction of the film, but I know why, because there are some dips out there that intentionally put the tape the OTHER direction with a pull-tab. Ugh! No silly, that takes more time to remove because once you pull on the tab, you now have to stop and separate the tape from the film. Why, why, why do some people do that?

We should actually make this a formal submission in the TIPS section, as this should be mandatory reading for anyone handling film.

I had one guy who used to apply the tape with the 'courtesy fold' the wrong way. He simply couldn't be told otherwise.

He gone now. [Razz]

Here at Doc Films we use at least 6" with a courtesy tab in the correct orientation.

I have a question: why emulsion out? Emulsion orientation depends on whether the reel is heads or tails out. We rewind in an under to over S-Curve (to mimic the path through our Simplex XL projector, changeover system) always with the soundtrack toward the operator. Most films come in to us tails-out. If the film is tails out, the emulsion side is inside while if the film is heads out the emulsion side is out. Since we're a changeover house, films coming in heads out are the bomb. Sometimes we receive instructions "Do Not Rewind" which to me says leave it as the film was taken-up at the projector, i.e. tails out and the emulsion side is "inside."

Thanks,

Years ago, Kodak did a study in regards to storing old acetate film emulsion in or out. They came to the conclusion that storing emulsion in (or was it out?) caused less film curling and a more even focus from the beginning to the end of the reel.

Personally, my experience from years of working with archival prints is that it really does not make much difference. For Polyester prints, the whole issue is mute.

No it doesn't, all four windings are possible, and not uncommon. I've actually had all four possibilities with different reels of the same print.

"Effect of Winding on the Projection Performance of 35mm Motion-Picture Film", SMPTE Journal, 1965 June.

SMPTE Recommended Practice RP-39,
Specifications for Maintaining an Emulsion-In Orientation on Theatrical Release Prints

IMAX recommends emulsion-in for optimal focus. IMAX prints have always been on polyester stock.

Before Brad jumps in on this:
quote: John Pytlak
Although SMPTE Recommended Practice RP39 specifies emulsion-in winding for optimum focus performance, it is based on Kodak tests with TRIACETATE prints on reels having small hubs. There is not enough data to specify the optimum winding orientation for polyester prints, and with the large hub diameter used on platters, the focus performance shouldn't vary too much with winding orientation anyway.
