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® Specifications:
Rubylith® are
available in both high and low tack (quick stripping) formulations.
High tack film is manufactured with an adhesive which produces
a tight bond between the film membrane and the polyester
backing sheet. High tack films are suitable for all types
of cutting, but are particularly suited to the cutting of
fine lines or details. Low tack films are produced with an
a dhesive which allows the film membrane to be peeled easily.
The "quick stripping" film is best suited for cutting
masks or positives which are bold or large format.
The
backing sheet, or support, provides dimensional stability
to the film. Although masking film coated on 300- gauge polyester
is predominant, 500- gauge polyester is recommended when
the application requires tight registration or the mask or
positive is large format. Rubylith® is available coated
on both 300- and 500- gauge polyester.
