Ok got a bit carried away and started changing my media out every 5 days instead of 7 days....Head projectionist reported 2 black blotches in film for a split second. She said she read too much film guard can cause this....We are back to a 7 day rotation. Is this true and is it possible for me to remove blotches manually....

Hi JanIf you'd used too much, you'd have more than two blotches, there would be many but all over the image, not just in one place and not just two AND not black. (It wasn't Star Wars you're talking about by any chance?)
If you HAVE overdone it (and it's most likely not, as we used to do the same thing here...we just found seven days was fine and anything else was wasting the product) then the media will even it out within a day and she'll be sparkling again.

Black blotches? No. The only thing that could be is airborne dirt that got on the film. FilmGuard cannot make black blotches.Ask your assistant where she read this please.
Regardless, 7 day rotation in most situations is optimal.

The only thing I've even encountered with Film Guard is the normal light streaking. What you've got sounds like dirt or a film defect. Try swapping out a couple frames of another film in it's place!

It has been 2096 days since the last post.

Having only recently purchased a Kelmar cleaner to use with Filmguard, I am still learning. One thing though I can't seem to aviod is the streaking. It just does not go away.
When I first applied Filmguard I was accused of the scratching the print!! The streaking is not as bad now but even after several days it's still there. I have followed the instructions and my only conclusion is that I applied just a little too much. I applied it until it got to the point where there was a few drops coming off the pads.
I am using the Kelmar media and are unable to get the Film-tech ones from my supplier as they don't stock them (but they stock Filmguard) ![[Confused]](confused.gif)
Would using the Film-tech media help?
Posted by Chris Slycord (Member # 4239) on 04-04-2008, 01:21 AM:
The directions say to apply enough that the media is soaked. Soaked and dripping are two different things.
You want to saturate the media pads not over-saturate them.
btw: Many people on here have said that you don't get streaking if you apply the cleaner to the media one day in advance of using it. So use less of it and apply it to the pad a day early.
Posted by Brad Miller (Member # 2) on 04-04-2008, 01:41 AM:
Ummmm, not quite.
You cannot "oversaturate" the media pads if you are using Film-Tech, or Kelmar pads. Maybe if there is some off brand I am unaware of that is super absorbent you can, but not with those main two brands. What brand are you using? (If you don't know, can you post a picture of a roll and the packaging?)
As far as saturating the pads, you should do it ONCE a WEEK. In no way should they be resaturated once a day...or worse, once a show! ![[Eek!]](eek.gif)
Who is your dealer in Australia? Intec-Pacific is the only authorized dealer over there (unless they are importing from Jack Roe in the UK), and Intec-Pacific does stock the Film-Tech media pads. Also what is your exact saturation schedule?

Hi Brad,
I am using the same media that came in the box the Kelmar Cleaner. When I ordered extra I was told I had the option of either the white or green media. I went with the white media.
I change over roughly every 5 days mostly because a lot of crap came off the soundtrack area and I noticed that at one point the SRD rack failed but was ok for the rest of the film.
I have 1 cleaner for 4 screens. The problem is that the films get shifted a lot from screen to screen and in some cases there may be 2 or more films on the one screen in the same day. I only ever run 1 film trough the cleaner though, usually the newest one.
I am currently looking into having the cleaner attached to all the platters not just the one but it seems to be a tricky setup (we have Cinemeccanica CNR-35 platters).
The supplier I use is Atlab Image and Sound.
I guess I should do the applying of the Filmguard to the media pads the day before as what I have been doing is loading the media, saturating them then lacing up and run the show with the second show been the first public screening for the day but that is not always the case.
I normally pre-screen the film so that the first run through is only to myself but with the current film passing through the cleaner,that did not happen. ![[Embarrassed]](redface.gif)

Would it be less difficult if the bracket were put at the top of the projector? That's a pretty common way to do it instead of on the platter.
Posted by Brad Miller (Member # 2) on 04-07-2008, 12:14 AM:
The green media is bad stuff. VERY abrasive. Don't ever buy that. Always stay with the white.
FilmGuard will absolutely NOT cause the SRD to fail. In fact it will preserve it and prevent it from failing. You probably just didn't notice that you had a bad section of the film in the first place.
As to your streaking question, I am baffled as to why you would still have the streaking past the first show or two. I have never come across that EXCEPT on "photoguarded" or "imageguarded" prints. I can almost bet that is what you have. Contact Atlab (the actual film printing lab) and inquire to see if they can tell you if your prints are coated in that shit. Many "rejuvenated" prints from the US will have that on it.
Posted by John Koutsoumis (Member # 1855) on 04-07-2008, 08:45 PM:
I have not checked with the distributor but the print is from the US and was used.
I also notice the streaking on the ads and trailers before hand.
The print came with black speckles constantly throughout the print and well as minor scratching. The scratching is gone as well most of the black speckles apart from an odd one here and there. Even the ends of reels are clean compared to when the print first arrived.
Not long ago a I received a print that labeled as been treated at the "Deluxe Labs Film Rejuvenation Centre" or something along those lines??
Posted by John Wilson (Member # 269) on 04-08-2008, 12:35 AM:
A rejuvenated print when treated with filmguard will look like your car does when it's polished and it rains. There will be dots of water 'streaming' down the print.
There are prints of 'Before The Devil Knows You're Dead' running around Sydney right now with only some reels not rejuvenated so it looks fine say for reel one (I do enjoy reel one of that movie, btw... ![[Big Grin]](biggrin.gif)
) yet when it goes to reel two it bubbles.
That doesn't explain your trailers though of course...

What does Rejuvenation mean?

What does Rejuvenation mean?
Rejuvenation is a scratch removal process where a chemical is baked into the base of the film stock to fill in non-emultion scratches. This is frequently done to old prints that are re-issued or for American prints that are sent overseas in a later release. It save the studio money, as it is a lot cheaper than striking new prints.
Posted by John Koutsoumis (Member # 1855) on 04-10-2008, 03:18 PM:
I received a print of the film "Bella" that had been through a Rejuvenation process. It still had visible base side scratches.
Posted by John Hawkinson (Member # 1135) on 04-10-2008, 08:01 PM:
It actually means different things to different people. Sometimes it is just washing the print in a solvent and redrying it, sometimes it can include buffing and coating, and other processes.
