In most cases, you can also see a slight difference in the "gloss" of each reel's sidewall as the roll sits on the platter, due to subtle differences in the cut each different slitter knife makes, and the slightly different scuffing of the edge of the film for each reel on different printing and processing machines at the lab. Kodak print film is slit from a 54-inch wide roll into 38 separate 35mm strips, so it's likely each reel is from a different strip: http://www.kodak.com/US/en/motion/support/h1/sizes.shtml IMHO, much of the problem is just having enough work light to see well enough to do a good job. If shows are running when you are loading or unloading a platter, use a spotlight to brightly light your work area without shining light into the theatre. With good light and a bit of experience, you'll usually be able to see the reel changes as the film sits on the platter, without need of marking the film in any way. ------------------ John P.

Kudos for all of you on this page! Opaque or Zebra tape is not needed, period!But, I will admit I use opaque tape as marker splices at the very start. I use them to the gauge the hand douser opening on the first preview. I always know where the splice is, and use a counddown in my mind waiting for the splice to go through the film trap. I never come on the screen by waiting for the change-over douser to open. I like the fade-ins.... I hate that when it goes "WHAM" and you are on the screen. I think I am a little more professional than that.

(i) I agree with John P's point about poorly-lit projection boxes being a factor in unsatisfactory film handling. I once did some relief shifts at a cinema where the work lighting was totally inadequate and had to be kept off as much as possible because of the enormous portholes (and their proximity to the back row of seats). I very quickly realised why all the prints in that box had a good 100ft of each reel edge-marked with chinagraph. You wouldn't have a hope in hell of seeing the end of a reel otherwise because the light was so bad. It would also explain why I discovered two trailers joined to each other out of rack. When I mentioned to the chief that I'd fixed the join, he told me that he'd been trying to correct it for the last week!(ii) In reply to Jamie's query about who inflicts the damage, I agree that lack of training and laziness have a part to play. But I'd also suggest that old and worn equipment which employers on a tight budget aren't willing to properly maintain are also an issue. Here's an example: there's a cinema near here which regularly sends us prints on crossover, nearly all of which arrive coated with heavy deposits of projector oil. Eventually I got so fed up with this that I 'phoned the place and spoke to their projectionist about it. She was very apologetic, and explained that a gasket was disintegrating where the intermittent unit was mounted to the chassis. However, no-one there was confident to remove an intermittent and the cheapest quote they'd had for an engineer call-out to come and replace the gasket was £250. The manager said he couldn't afford that, so she just keeps topping up the cross box as its oil gets sprayed onto the films. The projectionist has correctly identified a problem that is damaging prints, quite sensibly realised that she does not have the necessary skills to put it right, but then finds that she gets no backup from above. What to do about this? For one thing, if the distributors started billing this place for ultrasonically cleaning, rewashing and polishing all the prints they spray with oil, the manager might realise that £250 on repairs is money well spent...

"Artist's Tape" is designed to not leave a residue, although its' holding power is not very high. Although I don't recommend using it to mark splices, it is handy for taping down the ends of film rolls, or putting a write-on label on the leaders:"3M White Tape #256 3M-256/75 3/4" width 3M-256/1 1" width 3M Scotch™ Brand Artist's Tape Ideal for flapping and hinging, holds firmly yet removes easily without damaging artwork or leaving a sticky residue. Perfect for use on most illustration board, photos, acetate, and paper." http://www.camerastore.com/dl_cat_K/-K01_tape.html

Thanks very much for the replies.This research is for project report, unfortunately i need to back my own views up with real literature. You guys have been great in providing a source for that information. With regards To Leo, The cinema in question is not Harbor Lights by any chance. As you know we have very large portholes with back row seats near them. If so then the reason that they are big, is so that the 16 mm projector can be wheeled up and used. You also commented on the use of china graph, this is the method favored by my chief, although he makes sure it is very lightly applied. I use colored tape the same thickness as splicing tape. This is placed above the sprocket holes and over the top of the film. P.S, <center><font color="#FF0000"><font size=+1>THIS SECTION OF THE POST REMOVED BY MODERATOR.

Jamie - no, it's not Harbour Lights. I'm not going to name the cinema on this public forum because I don't want to upset or embarass anyone who works there and who might be reading this. But I will say that it is not a City Screen site. As I have written before on this list, a lot of substandard film handling takes place more because of substandard facilities than substandard projectionists. It was for this reason that I didn't feel it appropriate to name the venue.And on the subject of public lists: my e-mail to you of last week was off-list and private, because it discussed a third party. The cinema business in this country is pretty small, and from your public reply it will be obvious to lot of people who I referred to. It was for this reason that I e-mailed you confidentially, and I'd appreciate it if any replies would be sent the same way. If you look in the top right of the 'Forums' screen, you'll see that it says 'Registered Members - 728'. How many people regularly post messages on this site? I'd guess 40-50 at most. That means that the other 678-688 have either 'left' (as in, do not intend to re-visit the site but have not asked Brad to delete their registration) or are lurkers. That's an awful lot of potential lurkers, any one of whom might be the person you're talking about in a post. And you don't even have to be registered in order to read the messages here, which means that anybody and everybody is able to read what you or I write. The bottom line is that anything posted on this site (or any other listserv or newsgroup, even those with restricted membership) is effectively public, which was why my e-mail of last week was sent to you personally and not posted on this site. OK, rant over. I use Chinagraph for edge marking as well, and believe that it does not do any significant harm if (i) it is applied to the non-soundtrack side (hence I run prints base out on platters), (ii) it is applied as lightly as possible, and (iii) on 15-20 feet at the absolute most. This is QUITE enough to see the end of a reel under adequate worklights. As John P points out, it is sometimes possible to spot reel ends through stock changes (and lab joins too), but sorry, I'm too much of a wuss to rely on this when packing off 5 prints starting at midnight on a Thursday...
