Kodak's subsidiary FPC also sells projection leaders:

An overnight soak in a tub of dilute hypochlorite (laundry) bleach should dissolve the gelatin emulsion on old trailers. Rinse well with water and hang out to dry.

Do you have to iron the film after it has dried

It has too be so much fun to sit down and draw those framelines. A cliché here is that people in Italy hang their laundry to dry outside between their balconies. I can`t help picturing Mr Marcheselli`s balcony with all those drying film strips next to his socks

Michael,

And then thread the projector with my socks instead of the rinsed leader...
It could work!

John,
Thanks for the help on how to remove the emulsion but I think that it will be hard to make thousand and thousand of frameline on feet and feed of clear print! More, every time I used a black pen on the print I had what I wrote transferred on other part of the print.

I would like to founs the cheaper solution to have a framed leader to thread (non necessary a black leader, the cheaper one!) plus the START cue with a little piece of HQ black leader when the projector start projecting.
Since I need at least 20 different leader to thread, it will result in thousand of feet of frame of leader!

Why don't use virgin stock of print previously framed with some projections? How much a virgin stock of print could costs?

Bye
Antonio

Kodak VISION Color Print Film has a US catalog price of less than 10 cents per foot ($0.10 US) for the unexposed 35mm raw stock. To get an image on it (even just framelines), you need to print and process it:

Rich, where could I get my hands on the 1000' reel of clear leader? How much would that set me back?

John, actually you forget about buying reversal filmstock and running it through a projector with a high wattage lamp behind it and a 1.85 aperture. It's worked just fine for me.

Brad,

Reversal filmstock?

We used a reel of virgin print framed with a 4000W lamp. But sometimes that print has been spliced upside down and now when it is projected I have a soft 24Hz "hum" in the auditorium!!

Is there a way to "fix" the frame made with a lamp? I'm afraid that in few weeks/months, for projectionists mistakes, the leader will be completely unframed!!

Bye
Antonio

If you are trying to get physical development (no processing needed) to form the frameline images by running it though a lit projector, a good film to use is 35mm KODAK Black-and-White Print Film (ESTAR Base) SO-302:
http://www.kodak.com/US/en/motion/products/lab/so302.shtml

The intense light of the projector lamp will cause the silver halide to darken in the image area. As noted, eventually all the film will darken as it is exposed to light, especially if run multiple times at different framing positions.

To preserve the image, you would need to run the film through a fixer (hypo) to remove the silver halide that hasn't darkened to silver.
