Architects most requested ADA compliant technology in our industry
Many architects and designers are now requesting the Raster Braille process for ADA compliant signs. Raster Braille bead signs use a combination of pressure inserted domed Raster Braille beads and applied laser cut letters with tactile elements.
The technology behind raster bead
The Braille is formed by drilling a hole and inserting a small plastic or metal bead. Here are the ADA Specifications for your Raster Braille ADA Signage

- If text is multi-lined, Braille shall be placed below the entire text.

Even more benefits to Raster Bead ADA Signs
Signs can be designed with a full color background and even a raised logo. Each sign can have a different background and can be laser cut to any size and shape. This is a great option if you think that you’ll be adding signs on a continuing basis. Since there is not a minimum sign requirement when purchasing, it is an excellent choice for small offices and facilities.
