Masking Film - Ulano Universal Tack Level
Unfortunately, because of diminishing demand, Ulano stopped making Amberlith
at the end of 2007, so supplies are limited to existing stocks.
Ulano continues to make Rubylith that still has popularity in the photographic
world. It is a little darker, but will function the same as Amberlith for
In 2006 Ulano re-engineered Rubylith® and Amberlith® 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. Although you may notice slight color changes
in each, these are cosmetic and will not affect the light filtration (masking)
properties of the film.
will offer Rubylith® in 300 and 500 gauge but Amberlith® in only 300 gauge.
When ordering in the future, please specify RU (Rubylith® “Universal”) or
AU (Amberlith® “Universal”) and 3 or 5 mil thickness: RU3, RU5 and AU3.

Amberlith® continues to provide perfect filtration for color-blind black-and-white
camera film and for screen process photographic materials.
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.

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® and Amberlith® products to a broad graphic arts customer
base, which includes the screen printing industry.
Rubylith® and Amberlith® 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
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.
Amberlith Masking Film
Amberlith® is used primarily in the production of stencils
for screen process printing. The amber film is easier to see through than
the red, particularly when several sheets of film are overlaid to prepare
color separations. Amberlith® is an amber masking film. Amberlith® is "safe" for use with indirect gelatin
stencil films and diazo, diazo acrylic, or SBQ sensitized stencil films
or emulsions. Amberlith® is not "safe" for use
with camera speed darkroom films.
