Kodak's trade name is "ESTAR"®. Agfa's is "GEVAR"®. DuPont also called it "CRONAR"®.  |  IP: Logged Leo Enticknap Film God Posts: 7474 From: Loma Linda, CA Registered: Jul 2000 posted 12-16-2003 09:50 AM                        I can't understand why so many platter covers are made of cloth - like carpets in projection rooms, they're just dust repositories. Plastic ones are a much better idea, because dust cannot work its way in between the fibres. But the bottom line is that, assuming they're kept clean, they can't hurt and they can help, especially in a dusty projection box. As for leaders, in my cinema days I used to make up platter leaders as follows: 100 feet of used trailer with sync marks placed on it about 30 feet in, followed by 10 feet of clear spacing with opaque frame line to confirm that you're laced up in rack (i.e. an easy visual check as the film is running at full speed), followed by an Academy leader to time you into the show start. At the end of the print I would put a further 50 feet of used trailer to protect the tail, spliced the wrong way round to avoid any danger of the projector reading a digital track on it and switching over to Dolby or DTS. The beauty of this is that the length of used trailer takes all the abuse of lacing, ramping up to speed and accumulating the dust resulting from being left laced up and ready to go for several minutes. The framed spacing and leader, which you have to pay for, is as well protected as the actual print. Assuming it's polyester, it'll last forever and you'll only ever need to replace the length of used trailer.  |  IP: Logged
