Abstract

An apparatus and method for handling photographic film within the print-exposure section of a photographic printer. A mask matches the film frame (negative) and has a window for the passage of the exposure light. The mask also has holes through which air can be directed onto the film. A guide for the edges of the film parallels, and demarcates a gap with the mask. A source of air under either overpressure or underpressure supplies such air to the mask (4) and the film (1) through the air-direction openings (15). The air is supplied with overpressure while the film is being advanced. The air is supplied with underpressure while the print is being exposed to clamp the film.
