Rubylith Ulano Film – Light-Safe Masking Film for Precision and Craft

Whether you're hand-cutting stencils, masking screens, or prepping film positives the old-school way, Rubylith Ulano Film is a trusted classic that never goes out of style. Known for its deep ruby red color and precision-cutting performance, this light-safe masking film remains a favorite in screen printing, graphic arts, and electronics industries.

What is Rubylith Film?

Rubylith is a red masking film made of two layers: a light-safe red top layer and a clear polyester backing. The red emulsion layer peels away cleanly and is easily cut by hand or with a plotter, making it ideal for creating opaque film positives for screen burning.

Why Screen Printers Still Love It

"There's something satisfying about working with Rubylith—it forces you to slow down and really design with intent," says Jake, a printmaker and professor at a local art school. Artists, educators, and traditional screen printers choose Rubylith for its sharp line work, no-bleed edges, and ability to block UV light during exposure.

Common Uses:

• Hand-cut film positives for screen printing

• Blocking out areas on screens during exposure

• Stencil creation for photoresist processes

• Signage and archival applications

Key Features:

• Light-safe red emulsion: Safe under incandescent lighting

• Easy weeding: Clean separation from backing

• Precision-friendly: Ideal for fine detail and linework

• Available in sheets and rolls: Choose what fits your workflow

Specs:

• Film thickness: Approx. 4 mils

• Roll sizes: 24", 30", and 36" widths (yardage varies)

• Compatible with manual cutting and plotter systems

Elevate Your Hand-Cut Game

Rubylith Ulano Film isn’t just a product—it’s a rite of passage in the print world. If you value craftsmanship, hands-on control, and the ability to teach or demonstrate the fundamentals of screen printing, this is your go-to masking film.
