 Extended Descriptions


Ulano Rubylith RU3 Masking Film offers extended spectral protection suitable for platemaking and contact work for masking of photo-sensitive materials with orthchromatic sensitivity, and, of course, screen process photo stencil making. Ulano Rubylith RU3 Masking Film is used in every segment of the graphic arts industry and has gained such prominence that the Rubylith name has become synonymous with masking film. It is produced and distributed to a broad graphic arts customer base, including the screen printing industry.


Ulano Rubylith RU3 Masking Film is a red masking film that offers extended spectral protection. Safe for use with camera-speed darkroom films as well as indirect gelatin stencil films and diazo, diazo acrylic, or SBQ sensitized stencil films or emulsions, Rubylith is primarily used in the camera and plate making operations for offset lithography, flexography, gravure, and screen processes where orthochromatic films and plates are used. Re-engineered in 2006 to have a single “Ulano Universal Tack Level,” Ulano Rubylith RU3 Masking Film provides the tack level required by most plotter customers.

Working Instructions:

Slight color variations are cosmetic and will not affect the light filtration (masking) properties of the film. This light-safe, knife-cut film is coated onto a polyester backing sheet. Ulano Rubylith RU3 Masking Film can be cut manually or on a plotter. Rubylith has an emulsion thickness range of 1.1 - 1.2 mils.

Ulano Rubylith RU3 Masking Film can be used to produce:

  • masks for film contacting

  • plate making

  • film positives for photographic stencil production.
