1 Scope

1.1 This standard specifies the position and dimensions of 120 perforation repeat machine-readableidentification numbers. These numbers are intended to be a machine-readable version of the latent image keynumber. This standard also specifies the encoding format to be used for these machine-readable numbers, aswell as the area scanned and the spectral characteristics of the scanner.

1.2 This standard also specifies the position, dimensions, and content of human-readable identification (key)numbers for use on 65-mm motion-picture films intended for original photography or intermediate printingwhich also include the machine-readable key number described in 1.1. These numbers normally will beexposed onto the film at the time of manufacture.

1.3 This standard further specifies an area that may be used for optional manufacturer-specific film-typeidentification information.

1.4 This standard also specifies an area on the film which is not to be exposed by the film manufacturer, thusleaving it available for customer data recording.

1.5 Finally, this standard specifies optional frameline index marks.
