Author Topic: Film Hump Robert E. Allen Phenomenal Film Handler Posts: 1078 From: Checotah, Oklahoma Registered: Jul 2002 posted 02-16-2014 03:40 PM                     I received a pristine replacement print of "Ender's Game" and when it comes off the platter it develops a hump in the center section causing the platter to stop and start rather than run smoothly. Also, no matter which platter I put it on it will not take up tightly but our policy trailer and previews do just fine. What's with that?  |  IP: Logged Brad Miller Administrator Posts: 17775 From: Plano, TX (36.2 miles NW of Rockwall) Registered: May 99 posted 02-16-2014 03:43 PM                     If you look very carefully at the sprocket holes, you will see one side is slightly stressed. it might just be the corner of the sprocket holes, or the actual edge where the SDDS tracks would reside might be slightly creased. It won't hurt anything being ran on a platter. If you were running reel to reel then some cinch damage could happen over time due to the repeated stress of rewinding, but you aren't.  |  IP: Logged Louis Bornwasser Film God Posts: 4441 From: prospect ky usa Registered: Mar 2005 posted 02-16-2014 05:11 PM                        Occasionally there is a film that has the holes cut off square; one hole is ahead of the other just a little bit. Use a square or a piece of paper to determine this. Brad's idea also works. louis  |  IP: Logged Jim Cassedy Phenomenal Film Handler Posts: 1661 From: San Francisco, CA Registered: Dec 2006 posted 02-16-2014 08:08 PM                     ^^^^^^^^^ What Brad said. Especially if the print feels "spongy" after take up. (Which will also make it a bitch to move if you have to. The print will be verrrry 'floppy' needing as many clamps as you can get onto it. You might have to look at the perfs under magnificaion to see the defect, but every time I've had a print that handles this way, it's been some 'perforation related' issue.  |  IP: Logged Gordon McLeod Film God Posts: 9532 From: Toronto Ontario Canada Registered: Jun 99 posted 02-16-2014 09:50 PM                     Usually the pad roller in a simplex 5 star soundhead causes that damage  |  IP: Logged Robert E.

Thanks guys.  |  IP: Logged Bernie Anderson Jr Master Film Handler Posts: 435 From: Woodbridge, New Jersey Registered: Apr 2000 posted 02-18-2014 05:26 AM                        I've had that damage from Century projectors too. If you had a bad splice go through, some times it slightly pops off the sprocket and makes a hang nail on the corner of the sprocket hole.  |  IP: Logged
