| 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. Ulano continues to produce and distribute Rubylith® products to a broad graphic arts customer base, which includes the screen printing industry.
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.
Rubylith® RU3 is a high tack ruby film coated onto 300-gauge polyester. 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 has an emulsion thickness range of 1.1 - 1.2 mils. |
