The Jacquard Film Marker lets you create hand-drawn film negatives on Jacquard SolarFast Film for use with Jacquard SolarFast Dyes. It’s also ideal for making hand-drawn film positives for screen printing stencils when you’re using Jacquard Screen Printing Inks. The permanent, black ink goes down smoothly, dries instantly, and is non-toxic. Keep a few on hand for marking up or archiving photographic media as well.
