A perfectly flat surface insures maximum attainable resolution of detail, and provides perfectly straight lines without parallax distortion, when graphic elements are part of the presentation. A painted wall will frequently have undulation which results in wandering lines. Painted surfaces nearly always contain distracting surface artifacts from tape, sanding, and random surface texture differences.
Optical Coating Quality
Stewart fabrics are uniformly finished with automated equipment which ensures that all points on the screen are uniform in gain, gloss level, surface texture and off axis performance. The substrate of Stewart Filmscreen Corp fabrics are manufactured using the same precision automated equipment. To paint a wall with this sort of precision is not possible. Even if an automated machine is brought to the venue, the painted surface will only be as uniform as the substrate preparation allows. Most walls are painted with rollers or airless spray equipment neither of which is capable of applying a consistent stripe free or uniform coating.
Without a robotic applicator, there will be areas with distinct visible signature optical characteristics which represent the functional area of a particular application apparatus and the “reach” of the operator.
With a Stewart Filmscreen Corp product, the frame and screen can be installed in a single day. If the screen is greater than twenty feet tall, it may take a day and a half. The optical quality of the surface is engineered, measured, documented and optimal, prior to any installation effort.
A professional visual presentation is a powerful tool for communication. In today’s competitive technical business climate, a high performance screen surface, optimized for the venue’s application is a prudent investment which communicates a commitment to quality.
