Abstract:
A raised surface sign comprising:(1) a sign face layer, wherein the sign face layer comprises a substantially transparent, conformable, thermoplastic sheeting having an exposed face surface with Braille characters raised thereon; (2) one or more visual characters underlying the sign face layer; (3) one or more raised, 3-D characters in the form of a 3-D layer positioned beneath and in register with the one or more visual characters; (4) a principal background colour layer, underlying either the one or more visual characters or both the one or more visual characters and the 3-D characters and having an outer principal background colour layer border with and a colour layer surface having a specific colour; and (5) a substrate layer underlying the principal background colour layer and having a substrate underside and top side surface and a substrate border with a region of the substrate border that is displaced vertically with respect to the top side surface to form a Braille locator region wherein the Braille locator region is spanned by a coloured Braille locator spanning surface that is of the same colour as the colour of the surface of the outer colour layer border to minimize visual contrast along the substrate border between the Braille locator region and the outer layer border.
