电影彩印胶片 35mm 电影彩印胶片上厂家印制的潜影标记信息 规范

[中文适用范围]： 本国际标准规定了应用于 35 毫米彩色胶片上的人类可读潜像信息的位置、尺寸、内容和曝光。 该信息通常在制造时暴露在胶片上。 该国际标准还规定了胶片制造商不得暴露的光谱密度和胶片区域，从而使其可用于后续客户数据记录，例如音轨录制等。 [外文原描述]： This International Standard specifies the position, dimensions, content and exposure of human-readable, latent image information applied onto 35 mm colour-print film. This information is normally exposed onto the film at the time of manufacture. This International Standard also specifies spectral densities and a film area which is not to be exposed by the film manufacturer, thus leaving it available for subsequent customer data recording such as soundtrack recording, etc.
