Author Topic: Question on Digital Cinema John Hawkinson Film God Posts: 2273 From: Cambridge, MA, USA Registered: Feb 2002 posted 02-01-2008 02:13 PM                     No. That is bracket for Particle Transfer Rollers (PTRs). Filmguard requires a cleaner that supports dry (well, or wet) cloth media that can be advanced along with the film. --jhawk  |  IP: Logged Ron Funderburg Jedi Master Film Handler Posts: 814 From: Chickasha, Oklahoma, USA Registered: Nov 2007 posted 02-01-2008 02:18 PM                        Roger that appears to be a tacky surface cleaner not a film media cleaner. Film guard is liquid that you put on film media pads (rolls of film media actually) the one you are showing uses a tacky surface on roller to pull the dirt off the film and I don't recommend those at all.  |  IP: Logged Mike Blakesley Film God Posts: 12767 From: Forsyth, Montana Registered: Jun 99 posted 02-01-2008 05:11 PM                        Careful, Ron - John Pytlak might just come back and haunt you for that!  |  IP: Logged John Wilson Film God Posts: 5438 From: Sydney, Australia.

That's about all they're good for.  |  IP: Logged Adam Holland Film Handler Posts: 66 From: Oak Grove, LA Registered: Nov 2007 posted 02-01-2008 06:45 PM                     Roger, Our thaeatre is a 700 seat two level facility with the projection room being at the top of the upper deck. The port windows are about 100 feet from where the new screen will be and about 25 feet from ground level. We currently have 3000 watt lamp houses hooked up the the old equipment and that is the size Bill from TriState said we would need with the new simplex xl. If you are ever in Northeast Louisiana make sure you stop by to see us.  |  IP: Logged Brian Guckian Jedi Master Film Handler Posts: 594 From: Dublin, Ireland Registered: Apr 2003 posted 02-02-2008 12:14 PM                     Sounds like a nice project with some good advice behind it - good luck with it. quote: John Wilson That's about all they're good for. Is that fair? AFAIK PTRs were not designed for heavy cleaning duties, but to remove light material as found on negative stock and on new release prints. A case of "Horses for courses"?  |  IP: Logged Cameron Glendinning Jedi Master Film Handler Posts: 845 From: West Ryde, Sydney, NSW Australia Registered: Dec 2005 posted 02-02-2008 04:52 PM                     I tend to agree with John and Ron, The Wet Gate process of Filmguard not only improves the on screen look of film. It protects against mistread damage, brings second hand prints back to new condition and leaves most prints spotless. As with Dolby Digital 2k projectors claim "Opening Night Quality, Every night!" Filmguard is the only product that can allow film to do this. PTR's don't come close even when new! As they age they simply seem to move the dirt from one part of the print to another. PTR's do do something and are better than nothing, plus are enviromentally friendly.  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 02-02-2008 05:06 PM                     quote: Cameron Glendinning PTR's do do something and are better than nothing. You're absolutely correct! They spread the layer of dust and crap out evenly throughout the entire length of the film. So at least the crap layer is consistant for the duration. Actually, they are absolutely worthless for cleaning features in the average booth... and a job which they were never intended for. Proper use of FilmGuard is the only way to counter the dirt/crap problem.

Also, one is meant to swap out PTRs regularly and wash them.  |  IP: Logged Ron Funderburg Jedi Master Film Handler Posts: 814 From: Chickasha, Oklahoma, USA Registered: Nov 2007 posted 02-02-2008 08:29 PM                        Brian, give it up once the dogs have a bone they ain't going to let up no matter what you meant to so or not! Just have to chew and chew and chew! LOL ain't it grand!  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!! Posts: 12814 From: Annapolis, MD Registered: Dec 1999 posted 02-02-2008 09:05 PM                     Yeah, most people that pan PTR rollers have no clue on how to use them. If you are running them for an entire feature, they are not going to do well...they are a preventive cleaner to keep light dust off of a film and are the only in-booth cleaner for archival films. I use them in screening rooms and change the rollers for each and every reel. As such any dust on the film from the lab is removed as is any dusting due to projection. For main stream cinemas however, Film-Guard with a media cleaner is THE only way to go. Steve  |  IP: Logged Richard Fowler Film God Posts: 2392 From: Ft. Lauderdale, FL, USA Registered: Jun 2001 posted 02-03-2008 05:58 AM                     I use PTRs' for film festivals & premieres which helps minimize dust / wax build up in the gates, partically in straight gate V-5 machines. The painted film leader, especially red, is a dust leaver running through a warm film gate Most local festivals locally do not want any sort of wet cleaning due to liability or lack of time. Several times I have cut off film can padlocks with the O.K. of a studio represenative(s) who did not have the "combination"  |  IP: Logged
