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 Braille is formed by drilling a hole and inserting a small plastic or metal bead. The result is lasting and attractive.

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.

The Braille is formed by drilling a hole and inserting a small plastic or metal bead.
