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.
