Non-compliant letters and numbers may be applied to the sign face either by the application of die-

individually applied to the sign face are used for one-of-a-kind signs, such as direction signs.
Graphics that are silk screened directly onto the sign face are used for mass-produced signs, such as
regulation signs. If greater durability is required, the graphics may be applied to the reverse side of
clear matte acrylic, back sprayed with enamel and then bonded to a backing panel. Use adhesive
