Raster bead ADA Signs
As part of the Americans with Disabilities Act (ADA) all architectural signs are required to be ADA compliant. Examples of signs which have to be ADA signs are those that designate a restroom or other permanent room of a facility, those that describe the functional or accessible aspects of a room and those that identify entrances and exits.
How are Raster Bead ADA signs used
Raster Bead ADA braille signs are used for both interior and exterior applications. Raster beads are fabricated from metal when used in exterior applications and acrylic in interior applications. Acrylic beads are available in white, black and clear. Durability of the inks used are high in all applications and can be produced in any size or shape. The raster bead ada method has emerged as the preferred process for creating tactile/Braille signage for the blind and visually impaired.
The process is quite simple: our router drills holes into the substrate, and the Raster Braille Tool automatically inserts the spheres. Because the spheres fit perfectly into the holes, the resulting Braille is resistant to wear and exceedingly durable. The project is completed by digitally printing your design on the back surface. (if clear acrylic is fabricated). Also available as three dimensional printed signs.
There are a number of different sign technologies available for ADA signs. Graphic Impact is a fabricator for quite a few and each has advantages. Here is a comparison of photo polymer and raster bead techniques.
