Printing apparatus for photosensitive media having a hybrid light source

摘要

A writing apparatus (10) for forming images from digital data onto color motion picture film or other photosensitive media (32), the apparatus employing a single spatial light modulator (30) and having a hybrid light source (20) with three components: a red laser (40), a green laser (42), and one or more blue LEDs (18). Each component of the light source is adapted to the sensitometric response characteristics of a particular motion picture film type. The apparatus allows high-speed imaging to photosensitive media (32).
