Most engraving shops have much of what they need to start making ADA signs. Number one is, of course, a router or rotary engraver. If you start out with simple orders, you can purchase all your materials in a variety of colors, so you won’t use painted or printed backgrounds. Then, the only extras you need are the proper bits, a Braille translator, Braille font, and software to drive the engraver, a license for the Raster method for Braille, and preferably a small laminator to run the finished signs through so that characters fully adhere to the sign surface before the adhesive cures.
