Rubylith RM3 is a high-tack ruby film coated onto 300-gauge polyester.

Rubylith is normally used in graphic arts and screen-printing industries, however, it is an excellent product for amateur astronomers as well. Rubylith will produce very consistent results when used to create a night-safe red light out of normal white lights.

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.
