It’s true that there are several methods of fabricating raised-character and Braille signs. As an engraver, if you want to make the entire sign in-house without purchasing additional equipment, you need a license for the Raster method.
Most engraving machines have software available for drilling the precision holes you need to insert the Braille rasters. Note: the rasters should not have to be glued in place if they are acrylic and you are inserting them into acrylic plaques.
