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 stencil production.
