Abstract: One example embodiment disclosed herein includes apparatus including a sign substrate having a front and back side, and a first sign layer applied to the front side of the sign substrate. A masking layer covers the first sign layer, wherein the masking layer is adapted to block light from penetrating the masking layer and reaching the first sign layer. Also, a top sign layer is applied to a back side of the sign substrate or to a top surface of the masking layer. According to another example embodiment, a method provides for applying a masking layer over a first sign layer disposed on a sign substrate having a front and back side. The masking layer is adapted to block light from penetrating the masking layer and reaching the first sign layer. A top sign layer may be applied to the back side of the sign substrate or to a top surface of the masking layer.
