Why use projection paint over wall paint for a screen
Wall paint is designed and engineered principally to cover an underlying surface and to provide color in a room. These are relatively straightforward objectives and they are accomplished by paint manufacturers through the use of an inexpensive dispersion medium (typically, water-based acrylic or an oil-based medium) to which a pigment or pigments are added to provide color. Usually, relatively small amounts of pigment are used and then supplemented with extenders whose main purpose is to reduce the amount of expensive pigment required to produce the desired color. This can be done because the quantity of light reflected by wall paint is relatively unimportant.
By contrast, Screen Goo has been specifically engineered to accurately reflect and disperse the complex colored light patterns produced by video projectors. To that end, Screen Goo starts by employing a premium acrylic dispersion with very low light absorption characteristics and excellent durability. To minimize light loss and to ensure color fidelity, Screen Goo uses much greater concentrations of pigment than those found in house paint. excellent contrast.
These pigments are carefully chosen to accurately reflect the full spectrum of color produced by video projectors as opposed to house paints where the goal is to reflect that portion of the light which produces the single desired color. In addition, Goo Systems employs proprietary dispersion and pigment treatment techniques to maximize the reflective properties of the pigments employed. These techniques require custom built machinery and are very time and labor intensive.
Lastly, unlike wall paint which involves the application of a single product, a Screen Goo application consists of two different products. A single coat of Screen Goo Premium 100% Acrylic Base Primer provides an ideal reflective surface to which 2 succeeding coats of our diffusive, color correct Goo 2.0 Finish Coats are added. It is the combination of the Reflective Premium Screen Goo Acrylic Coat and the diffusive Goo 2.0 Finish Coats which gives a Screen Goo screen its remarkable qualities of high reflectivity, color accuracy, wide viewing angles and excellent contrast. The icing on the cake is the very special sense of image depth, or feeling of looking into the picture that only a Screen Goo screen provides.
