Abstract
A method of producing a film is provided. The method involves a winding step including a point-of-interest detecting step including detecting a point-of-interest on the film, a number-of-turns counting step including counting the number of turns of the film wound around a winding core, and a number-of-turns storing step including storing, in association with the number of turns of the film wound around the winding core, a position of the point-of-interest in a direction of transfer of the film. The method eliminates the need for a step of printing on a film for the purpose of locating a point-of-interest on the film.
