KS perfs
Kodak Standard 35mm positive perforations 1. Designed with a higher perforation than the Bell&Howell (BH) perforation, it has rounded corners to provide added strength.
This perforation, commonly known as the KS or ‘positive’ perforation, has since become the world standard for 35mm projection print films.
