Patent

CA 2599850

There are provided film printing systems and methods for printing images on one of two different width film stocks. A method for printing images on one of two different width film stocks includes the step of combining each of three different color light streams into a combined color stream. The method further includes the step of directing the combined color stream into a hybrid lens that focuses the combined color stream onto one of the two different width film stocks such that a uniformity of the combined color stream remains the same regardless of film width.

L'invention concerne des systèmes d'impression de film et des procédés d'impression d'images sur l'un de deux films de largeurs différentes. Le procédé d'impression d'images sur l'un de deux films de largeurs différentes comporte les étapes consistant à: combiner chacun des trois flux colorés différents de manière à former un flux coloré combiné; diriger le flux coloré combiné dans un objectif hybride qui concentre ledit flux sur l'un des deux films aux largeurs différentes, de sorte que l'uniformité du flux coloré combiné reste la même, quelle que soit la largeur du film.
