Here's why:
* Release print implies that the film is ready to be distributed and shown in theaters or on other platforms.
* It is the final version, meaning all edits, special effects, and sound mixing have been completed.
* Prints are physical copies of the film, usually made on celluloid (for older films) or digital media.
Sometimes you might hear it referred to as the final cut or final master, but "release print" is the most common and specific term for the final version of a feature film.
