System and method for film watermarking |
摘要 |
A system and method for watermarking a film includes a light source array including one or more light sources having light directed toward a film to be watermarked. A control mechanism is configured to synchronize a position of the film with the light sources such that the light sources are activated to record a watermark on the film to identify an aspect of the film, wherein the watermark includes a plurality of spots aligned transversely to a direction of film motion during printing of the film.
