We’ve even printed on 35mm film negatives with our inkjet printer which looks really cool for travel projects. But while the pouch may improve the print quality on transparency film, a spray fixative is necessary to prevent the ink from rubbing off. After treating the transparency with the pouch and printing on normal settings, let the ink dry thoroughly. If you want to remove the powder, lightly dab with the Perfect Cleaning Cloth or a soft brush after the ink is completely dry, before spraying the fixative.
Note: Polyester film, such as film negatives and ‘write-on’ transparencies are acid free and archivally safe. Most ink jet transparencies are treated with acid to create an inkjet-friendly matte surface, and are not acid free. If archival-safety is important to you, use uncoated ‘write on’ film, or make sure the packaging specifies ‘archivally-safe’.
