Rubylith Masking Film 305mm x 250mm

$11.00

Rubylith is a red Masking Film  0.127 mm thick 305mm x 250mm – Used to create masks to block UV light when contact printing.

Rubylith is also used in the camera and plate making operations for offset lithography, flexography, gravure, and screen processes where orthochromatic films and plates are used.
This light-safe, knife-cut film is coated onto a polyester backing sheet. It can be cut manually or on a plotter to produce masks for film contacting, plate making, and film positives for photographic stencil production.  Slight color variations are cosmetic and will not affect the light filtration (masking) properties of the film.
