MACal 9798-30Pro is a translucent, non-colored vinyl, which allows 30% of light to pass through the vinyl. The face is a matte finished 3-mil cadmium-free vinyl. The film is coated with a durable permanent acrylic adhesive with excellent wet out characteristics for clarity. An 83# white kraft liner offers stability and layflat. The product has good dimensional stability and is designed for excellent cutting and weed ability. This product is specifically designed for backlit applications in combination with 9700Pro colors and 9722-00 Pro Light Stop vinyl. These films give a more homogenous light diffusion from the light box. They modify the “night” colors of the MACal 9700Pro creating different shades of color for nighttime illumination.
