Film Positive

A film positive is a transparent film displaying a positive image, typically used in printing processes like screen printing.

This film acts as a stencil during the photo-exposure process. In screen printing, for example, the film positive is placed on a screen coated with photosensitive emulsion and then exposed to light. The areas of the emulsion that are not covered by the film harden, while the covered areas remain soft and can be washed out, creating a screen stencil for printing. The use of film positives is common in various forms of printing and lithography, making it a crucial element in these processes.
