"The rules continue to help our soci- ety and our industry grow in our meth- odologies for production," Kelly says, adding that what the customer desires for the signs "needs to be filtered through the rules and regulations of ADA." ADA-compliant signs are most com- monly made out of acrylic, but other materials can be used, such as plastic laminate, wood, aluminum, brass, stain- less steel and other metals. Acrylic is a cost-effective option that saves a few steps and time in the produc- tion process, Kelly says. The material is pre-colored and pre-engineered in the right thickness and with the necessary qualities that meet the specific require- ments of ADA, he says. "Outside of that, if you go to non- colored plastics and aluminums, you have to paint them yourself," Kelly says. "You have to put a finish on it that would be equal to a non-glare material." Appliqué Production Method To produce the signs, the Braille dots and raised images are either added to the sign's surface, or material is removed to create a solid piece consisting of both the dots and images and the sign sur- face. The methods include appliqué with Braille raster beads, digital or direct color printing, water or chemical etching, sand carving, and thermoforming or thermo- compression. "Photopolymer and thermo-com- pression both have Braille that is integral to its substrate, meaning that the Braille dot is not 'stuck on,' nor are the individ- ual beads placed into a hole. The Braille is a part of the backer, or substrate, mate- rial," says Tina Kirk, general manager of Bell Company, Inc., in Trussville, Alabama. "Raster beads require drilling a hole for each Braille bead in a cell and then adding in individual Braille beads to fill those voids." Acrylic room-identifica- tion signs.
