There are installations where a desired level of black level enhancement is achievable with our classic standard Screen Goo formulations, but where there is not enough projector light output available to provide a sufficiently bright image. In these instances, a screen surface with greater controlled reflectivity or gain can be a valuable option. One of the key attributes of Screen Goo is its ability to maintain great Black Levels in varying ambient light conditions. The value of our +20 series projection coatings is in their ability to allow the user to make a bigger image or use a less expensive projector for a given image size. While more expensive than our standard matte coatings, our +20 series coatings save our customers the cost of a brighter projector and provide a more dynamic image. In particular, customers projecting in active 3D will benefit from the increased reflectivity of our +20 coatings.
