(I think it's generally a much worse idea to hijack a newcomer's thread with irrelevant [irreverent?] technical discussions...it's one thing to do it to experienced F-T people, but when someone asks a simple question, let's try to keep their thread on topic.) Some people have asked if the labs still edgewax. Since we seem to not have any laboratory or film stock manufacturer representatives here anymore, it's a bit tough to say with strong authority. However, please note the Processing KODAK Color Print Films, Module 9; Process ECP-2E Specifications last updated in 2006 says: quote: ECP2E Film Lubrication Edgewax 35 mm and wider films with a paraffin-based lubricant (approximately 50 g/L). Full coat 16 and 8 mm films with a less dense lubricant such as a 0.5 g/L PE Tetrasterate solution (RP 48-1984). See Module 2, Equipment and Procedures, for formulas and details. ECP-2E is the current print film developing process. It's the process for KODAK VISION Color Print Film / 2383 and KODAK VISION Premier Color Print Film / 2393. It's a revision of process ECP-2D that removes the first fixer and soundtrack redeveloper -- i.e., it has been revised for cyan dye track films. --jhawk  |  IP: Logged Scott Norwood Film God Posts: 8146 From: Boston, MA.

For the record though, a head guy at a major lab also told me a couple of years ago that edge waxing had been stopped years ago.  |  IP: Logged Richard P.

Black & White can be a problem if used in continuous projection, such as platters in commercial theaters. It's no problem with the brief runs of most of the type theaters that run older films, and even then not if the print has had some use. Many of you will remember the shedding and emulsion build up of the dye transfer prints Technicolor tried to revive about 10 years ago, especially GONE WITH THE WIND. The basic print stock was b&w. When WB released GOOD NIGHT AND GOOD LUCK they arranged for the lab (Technicolor) to wax the prints to prevent this problem.
