ADA Compliant and Braille Signage

Produce Americans with Disabilities Act compliant signs for any building.

Both attractive and durable, the Raster™ Braille method completes the look and feel of your signage project. Raster® Braille meets the most recent U.S.A. federal standards. When producing signs, the Braille message should accurately represent the tactile message. Spacing changes the meaning of letters and numbers. It is important to use GravoStyle™ software to accurately translate the Braille. It is also very important to proofread the Braille translation to ensure accuracy.

  • Details

    For a better ADA sign use the best plastic. Gravograph offers a number of ADA compliant products to fit any signage project.  

    The Americans with Disabilities Act was created in 1990 with one goal: to prohibit unjustified discrimination based on disability. This act requires employers to make reasonable accommodations to employees with disabilities and also requires accessibility for public accommodations. One aspect of these public accommodations relates directly to sign fabricators, the creation of ADA signage.


    ADA signage fabrication can bring a new revenue stream to a sign shop. A simple ADA sign can be created for as little as $3.00. With some creative aspects from rotary or laser engravers, tactile lettering, and Braille beads, that simple sign can be sold for upwards of $90.00. Here, will discuss the ins and outs of ADA sign fabrication and the rules and regulations that apply in the United States.
