Author Topic: Projector's cleaning method for archive Scott Norwood Film God Posts: 8146 From: Boston, MA. USA (1774.21 miles northeast of Dallas) Registered: Jun 99 posted 05-19-2016 08:52 PM                        Film Guard doesn't really apply to most repertory screenings, anyway, since they are usually one-offs. The real benefit to it is for long-term engagements, not single screenings.  |  IP: Logged Kenneth Wuepper Phenomenal Film Handler Posts: 1026 From: Saginaw, MI, USA Registered: Feb 2002 posted 05-19-2016 09:00 PM                     The old remedy for "green prints" was to have a little block of canning wax available to apply to the film edges outside the sprocket holes. This paraffin stopped the gate chatter and was acceptable to the exchange.  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 05-21-2016 09:56 AM                     Ken, I don't think they have made canning wax since 1892.

It was done by at least one major archive, too - British Film Institute archive prints in the 1980s and '90s would often arrived with large red WAXED stickers on the cans. The smell of a waxed reel was distinctive when you opened the can, and in retrospect I wonder if those vapors weren't helping when it came to acetate decomposition. I've never (that I can remember) come across a waxed polyester print, though. I'm guessing that the thinner stock means that the friction issue that can be addressed by edge waxing acetate doesn't exist, and therefore that waxing a polyester print wouldn't achieve anything.  |  IP: Logged Gordon McLeod Film God Posts: 9532 From: Toronto Ontario Canada Registered: Jun 99 posted 05-22-2016 12:24 PM                     deluxe canada edge waxed all prints until they closed the facility  |  IP: Logged Kenneth Wuepper Phenomenal Film Handler Posts: 1026 From: Saginaw, MI, USA Registered: Feb 2002 posted 05-22-2016 01:10 PM                     Thanks Gordon, I knew that the practice was still being done.

None of the prints I've seen coming out of FotoKem recently have been edge waxed.  |  IP: Logged Manny Knowles "What are these things and WHY are they BLUE???"

Photos are part-way down the page. There have been a few occasions where I got permission to clean up a filthy repertory (or "sub-run") print*, and Steve's method is, in my opinion, the best way to do it, because it affords the ability to do multiple passes in less-than-real-time. Perfect for a "one off" screening. *I do make a distinction between "repertory" and "archival" prints.  |  IP: Logged Monte L Fullmer Film God Posts: 8367 From: Nampa, Idaho, USA Registered: Nov 2004 posted 05-25-2016 06:32 PM                     Some Kelmar tables did have the threaded hole made to attach these Kelmar brackets as with what Steve had set up for bench cleaning. I'd did the same with 16mm films on a Kelmar table since the rollers on the bracket had the inner grooving set for the 16mm width.  |  IP: Logged
