Disclosed is an apparatus for applying indicia to processed cinematic film, where film includes a cellulosic substrate layer and at least one emulsion layer. The apparatus comprises: a UV pulse laser for generating a laser beam capable of vaporizing the emulsion; a mechanism for directing the beam to the emulsion; a mask interposed between the laser and the film; the mask has UV-transparent portions in the shape of the indicia, which allow the beam to pass through the mask and impinge upon the film and vaporize the emulsion in the shape of the indicia; a modulator responsive to the indicia for controlling the intensity and duration of the beam; a film transport mechanism; an alignment mechanism for aligning the laser with the indicia and with a frame of the film; and a transport mechanism responsive to the indicia for transporting the film to bring a desired film frame in alignment with the laser mask. |
