What is rubylith?

Rubylith is a brand of red masking film used by artists, graphic designers, and printers for creating stencils and masks for screen printing or other graphic design applications. The film is typically made from a thin, flexible sheet of red light-sensitive material that can be cut with a knife or blade to create detailed designs.

Rubylith is often used in conjunction with other materials such as amberlith (yellow masking film) and lith film to create multi-layered stencils for screen printing. The red color of Rubylith makes it easy to see and work with, especially when cutting out intricate shapes or fine details.

Once a design has been cut out of Rubylith, it can be placed directly onto a screen or other surface and exposed to light to create a stencil. The areas covered by Rubylith will remain unexposed and can be washed away, leaving behind a negative image that can be used for printing.

Rubylith is a versatile and popular material for artists and designers due to its ease of use, flexibility, and the ability to create highly detailed designs. It can be used for creating everything from simple text and logos to complex illustrations and photographic images.
