Have a print of 'It's a Wonderful Life' in at the moment. On the ends of the reels and leaders, where the splicing tape has been peeled off, the emulsion has come away with it, sometimes in quite large areas, as can be seen here:
The emulsion has come off the base quite cleanly, the dark marks in the picture are just sticky muck from the tape. I have never seen anything like this before; does anybody know what is causing it? Most of the emulsion was missing before the old tape which I removed was applied, so I don't know what type of tape removed it.
The print is on Kodak stock, with a triacetate base. I don't know the date of the stock, but think the print probably dates from the 50th anniversary release. [ 12-18-2005, 02:11 PM: Message edited by: Stephen Furley ]

Monte, I don't know what this what negative this print was struck from, though I doubt that it was an original one. I don't think there are any negative edge markings on the print, though I didn't look that closely at it. However, the negative used couldn't possibly cause emulsion peeling on the print film. I've never seen this sort of thing on any film stock, black and white or colour, negative or positive, any gauge, any age, nitrate, diacetate, triacetate, or polyester. About the nearest thing I've seen is around the edges of glass plates, I think caused by mis-handling while wet. I've never seen dry emulsion peel away from the base in large areas like this.
quote: Dan Lyons Is the rest of the film as dirty and scratchy as that one frame?
The print is generally very good, apart from a couple of slight scratches, which don't last very long. I removed this frame from the end of a reel when making up the print; I don't like doing that, but I don't really think I had much choice in this case. I brought the frame home to scan, but I don't have any suitable solvent handy to remove the muck that several generations of splicing tape have left behind.
