Masking Film

Ulano Universal Tack Level

Amberlith Masking Film

In 2006 Ulano re-engineered Rubylith® to have a single, “Ulano Universal Tack Level.” We took a fresh look at the common uses of masking film now, not those of a generation ago. We concluded that very few customers cut intricate designs by hand, so the need for high tack masking films was was not necessary. Ulano Universal Tack Level provides the tack level most plotter customers want, and simplifies the inventory requirements of our distributors.

We will offer Rubylith® coated on 300 and 500 gauge polyester. When ordering please specify RU (Rubylith® “Universal”) and 3 or 5 mil thickness: RU3, and RU5. Our numeric codes for roll dimensions (like 202 for 40" X 150"), remain the same.

Rubylith® 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.

Rubylith® can be ordered in custom-cut sheets (e.g. USA letter or European A4, A3, etc.) or in the roll sizes listed below.

We Invented Masking Film

The Ulano Corporation gained worldwide recognition within the graphic arts industry with the invention and promotion of the first masking film: Rubylith®. Rubylith® is used in every segment of the graphic arts and has gained such prominence that the Rubylith® brand has become synonymous with masking film, much as Kleenex is synonymous with facial tissue. Ulano continues to produce and distribute Rubylith®products to a broad graphic arts customer base, which includes the screen printing industry.

Rubylith®brand masking films are "light safe" knife cut films coated onto a polyester backing sheet. These films can be cut manually or on a plotter to produce masks for film contacting and plate making and film positives for photographic stencil production.

Rubylith® Masking Film

Rubylith® is a red masking film, which is suited for use with orthochromatic films. Rubylith® is "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.
