Well, when Terry Westenshow.....whatever it was...I think it is Terry Smith now, sent me a sample of PTRs years ago, I found they didn't work well at all, and in fact made the print extremely dirty (Addams Family I...two prints, identical projectors) as opposed to the one cleaned once with a dry web media cleaner. Granted, I'm sure the PTR technology has improved much since then, but the most recent PTRs I have tested were about a year ago (from FPC) and were less sticky than the originals from that early 1990s test and did not work as well. I do believe they were to "reduce static." Since then a fellow recommended I blow 2 bucks on a "cat hair" roller at the impulse isle at the local Wal-Mart and cut it into strips for placement on the PTR. This actually worked fairly decent. The best part is I could peel it off and toss it when the show was done! How about getting FPC to make roller versions of these where at the end of the show, the top layer can simply be peeled off to reveal another 20 or so layers underneath??? That might sell and would certainly be quicker and easier on the projectionist.Gordon's idea of using packing tape does make sense. I will give it a try as I have many PTRs laying around to test with. Gordon, can you give us the information as to the brand and supplier of the PTRs you are speaking of? It would be interesting to test. I am always willing to try new products and ideas, even though I doubt it could do any better than FilmGuard. Also, how about testing FilmGuard on an IMAX print?

The only way I have seen PTRs work effectively is to start with a clean print. If one cleans a print with a media cleaner so it is clean...then has 2-3 sets of PTRs for EACH screen...one can run EVERY show through the PTRs and carry his/her bucket-O-PTRs around and swap out used for fresh during thread up. By having 3-sets, you have one running the show, one cleaning and one drying (obviously doing the cleaning/drying while the shows are running). This way, the film never gets any build up of dirt to clog the rollers. Still seems like a lot of work to me! I think PTRs have their place but they are anything but a cure all and are sold to people not prepared on how to use them and using merely two rollers (one base side and one emultion) isn't necessarliy wise either...perhaps increasing the number of rollers in the cluster would improve the results. But frankly, of the booths I've been in (with the exception of those operated by Gary Weyers...currently at the IMAX 3-D in Indianapolis, IN) they only use one set and they are mostly BLACK can covered with "stuff". Then again, I often don't see the media cleaners with their media threaded right either...that upper one always gets em. Steve
