本国际标准规定了人类可读的、潜在的 应用于35毫米彩色打印胶片上的图像信息。这些信息通常会以最快的速度暴露在胶片上 制造时间。 本国际标准还规定了光谱密度和胶片不暴露的胶片面积 制造商，从而使其可用于后续的客户数据记录，如配乐记录等。

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.
