When I asked for black leader that is not mylar with frame lines (which show on screen at my location), all I get is a "HUH?". It plays fine, but the white frame lines are impossible to get rid of (they are VERY thick). My supplier (apparently) doesn't know about a solid black leader.

Hadden has always supplied BB-100 from N T Audio Visual. This is solid black 35mm film with soundtrack & frame lines printed on. There is no translucency; solid black. Louis

Well, sort of. When it's brand new it blocks out quite a lot of light, but if you compare it running and open/close the douser, you will see it isn't truly blocking all light.

My beef with it is that it is easily scratched, and the scratches show up quite lovely on screen. Mag fullcoat is a far superior type of film to be using for "black leader", as it is as opaque as it gets, plus it takes quite a lot to scratch it. The only problem is that it doesn't have any frameline markings, but that's where I come in.

End result, I make the best black leader. (I've just never put it on the market.) [Big Grin]

If someone made black leader with framelines using KODAK VISION Premier Color Print Film 2393, they could actually have the opaque areas of the leader have a density greater than 5.0 (Only 1/100,000 of the light gets through) -- that's pretty black. [thumbsup]

Here are the magnetic fullcoat films that Kodak FPC stocks:

Brad,
I guess that is what's going through the film cleaner in your pix.

When ordering mag fullcoat, be sure to get the thicker (5mil) variety. This is comparable to standard print stock. The thinner version has trouble running through some projectors. FPC seems to be the best brand for use as black leader; some of the others that I have tried will eventually scratch and become less-than-opaque (but are still better than the "B100" variety).

How do you add the framelines (I have been using a frame counter and permanent marker)

How? It's magic. [Cool]

John, the problem with using Kodak stock is that it wouldn't be any more scratch resistant than the existing leaders on the market today. [Frown]

FPC fullcoat as Scott mentioned is a far superior choice.

Another advantage is that on some formulations at least (e.g. the Zonal acetate stuff that was kicking around until I left the booth in 2001), the oxide coating picks up dust and dirt and helps keep the film path clean, especially if you run 50-100 feet of it at the head and tail of a platter roll.

Brad's fullcoat stock with frame markings rules! I use this stuff between older trailers all the time, makes the transitions a little nicer, since they tend to end abruptly.
