This is a first for us. Ordinarily we take up nice and tight...nice and smooth. This is how our print of Ali is taking up and paying out. 
 There is no visible damage to this print. There are no raised sprockets. It was brand new when it went to another theatre for two screenings then straight to us. It took up badly there also. Suggestions? ------------------

Hi BradWe have requested another print. There's no way I'm going to attempt to move this. The prints, BTW, are local. ------------------

Hi FrankGood to hear from you again. This print would do the same on 6k's for sure. It's got the same effect as it would have had it been taken up with a very loosened off take up belt...even worse perhaps. Hi Jeff, Welcome to the forum. I've tried soundtrack up then soundtrack down. There's minimal difference. It takes up very marginally better down, but it's still loose as a you-know-what.  ------------------

Actually that can happen with film mounted on 2,000 foot spools, though I've only experienced it with nitrate and acetate, not polyester. The reason it happens in nitrate and acetate is that the base shrinks over time as the nitric or acetic acid leaches out of it. Eventually the shrinking base puts pressure on, and then deforms the emulsion, resulting in uneven winding.It's not too much of an issue with nitrate because if a reel is measured at over 3% linear shrinkage, it's not safe to project. But early acetate prints are still shown in rep houses after quite severe shrinkage, and in these places having a separate motor driving the take-up spool (as distinct from the take-up spool being driven by a chain or belt from the main motor) is useful, because you can increase the pressure slightly to ensure a smooth take-up. But as I say, I've never experienced this syndrome with polyester, which is not supposed to shrink. Given that this is an almost new print, the only guesses which come to mind are that (i) it was dried too intensively by the air knife in the lab's processing machine, which caused the swollen emulsion to shrink very rapidly, thus distorting the base, and (ii) the effect of a static electricity build-up. However, if you've never experienced this problem with any other films, it does seem that this is print-specific. A fault with the antistatic layer on the print stock, perhaps? On balance, I'd vote for the emulsion having been shrunk by overdrying, as this is consistent with Jeff's observation that the uneven winding is reduced by mounting the print emulsion in.

I think Peter Berrett's dog may have pee'd on it at some point.  If you pull a three feet section and hold only one edge doing this, the other edge is far from tight. I would say it's in the printing, but the distributor says we are the only ones to complain...of course, not many theatres have thought about moving it yet. Maybe on Thursday morning they may be getting a few phone calls from around the traps for replacement prints because they have just lost it all over the floor. (We run Thursday to Wednesday).  Just remember...you heard it here first, folks. ------------------

Intesting about your print of ALI John,Our print is taking up smooth and tight with the same platters as yours.I 'm guessing that our print came from the same lab as your's also.Actually I moved it the other day and it remained tight so perhapes your print is of a different stock.Do you take up with sound track up or down.Steve.
