1、SMPTE STANDARD ANSVSMPTE 300-2002 Reaffirmation and Redesignation of ANSVSMPTE 300-1997 for Motion-Picture Color Print Film (35-mm) - Manufacturer-Printed Latent Image Identification Information Page 1 of 3 pages 1 Scope This standard specifies the position, dimensions, content, and exposure of huma

2、n-readable, latent image information applied onto 35-mm color print film. This information is normally exposed onto the film at the time of manufacture. This standard also specifies spectral densities and a film area which is not to be exposed by the film manufacturer, thus leaving it available for

3、subsequent customer data recording such as sound track recording, etc. 2 Application This standard applies to the latent image information applied on the edge of 35-mm color print film by the film manufacturer. 3 Normative reference - The following standard contains provisions which, through referen

10、ure. 5.2 Dimensions The height and position of the latent image information shall be located in the margin between the edge of the film and the perforations on one edge of the film. The edge of the film with the edgeprint is designated the “printed edge” by the manufacturer. 5.3 Use of other margin

11、areas No latent image information shall be placed along the opposite edge of the film (nonprinted edge). This area and the area between the perforations are reserved for data recording in subsequent operations (.e., sound tracks, time codes, etc.). Page 2 of 3 pages ANSVSMPTE 300.2002 5.4 Content Th

12、e specific content of the information shall be at the discretion of the manufacturer. However, this information usually includes manufacturer information, film and batch number information, and other manufacturer data. The edgeprint may also include a control dot for print density control, approxima

13、tely 0.05 in (1.2 mm) in diameter. 5.5 Repeat frequency The repeat frequency of the edgeprint (figure 2) shall be at the discretion of the manufacturer. Typically, this repeat frequency is 36 in (914 mm) or less. 5.6 Exposure 5.6.1 The latent image information shall be applied such that the blue and

14、/or green sensitive layers of the film are exposed. Exposure of the red sensitive layer is reserved for data recording in subsequent operations (.e., sound tracks, time codes, etc.). The status A red density of the edgeprint after the film is processed through the manufacturer?s recommended process

15、shall not exceed Dmin + 0.20. 5.6.2 The density of the manufacturer?s edgeprint shall be such that it is human-readable in ordinary room lighting. 5.7 Orientation The edgeprint may be placed in one of several orientations at the discretion of the film manufacturer. When the film is held with the emu

16、lsion toward the viewer and the head toward the right, the edgeprint may be in any one of the following orientations: - right side up, reading from head to tail; - upside down, reading from head to tail; - right side up, reading from tail to head; - upside down, reading from tail to head.
