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.

Claims

1. A method comprising:

applying a masking layer, that includes a foil with an adhesive pre-applied to the foil, over a first traffic message disposed on a reflective traffic sign that has a sign substrate having a front and back side, wherein the front side has a reflective surface, wherein the masking layer is adapted to block light from penetrating the masking layer and reaching the reflective surface and the first traffic message; and

applying a top sign layer to a surface of the sign substrate, wherein applying the top sign layer to the surface of the sign substrate includes applying the top sign layer to a back side of the sign substrate, and turning the sign substrate around so that the top sign layer is facing in an operable direction.

2. The method of claim 1, further comprising forming the foil from aluminum.

3. The method of claim 1, further comprising forming the foil from zinc.

4. A method comprising:

applying a masking layer over a first traffic message disposed on a reflective traffic sign that has a sign substrate having a front and back side, wherein the front side includes a reflective surface and wherein the masking layer includes an adhesive pre-applied on one side thereof, wherein the masking layer is adapted to block light from penetrating the masking layer and reaching the first traffic message and reflecting off the reflective surface; and

applying a top sign layer to the back side of the sign substrate, wherein applying the top sign layer to the back side of the sign substrate includes turning the sign substrate around so that the top sign layer is facing in an operable direction.

5. The method of claim 4, wherein applying a masking layer includes laminating the masking layer over the first traffic message.

6. The method of claim 4, further comprising forming the masking layer from aluminum.

7. The method of claim 4, further comprising forming the masking layer from zinc.

8. A method comprising:

applying a masking layer, that includes an adhesive pre-applied to the layer, over a first traffic message disposed on a sign substrate having a front and back side;

wherein the masking layer is adapted to block light from penetrating the masking layer and reaching the first traffic message; and

applying a top sign layer to a surface of the sign substrate,

wherein applying the top sign layer to the surface of the sign substrate includes applying a top sign layer to a back side of the sign substrate, and turning the sign substrate around so that the top sign layer is facing in an operable direction.

9. The method of claim 8, wherein applying a masking layer includes applying a foil.

10. The method of claim 8, wherein applying a masking layer includes laminating the masking layer over the first traffic message.

11. A method comprising:

applying a masking layer, that includes a foil with an adhesive pre-applied to the foil, over a first traffic message disposed on a reflective traffic sign that has a sign substrate having a front and back side, wherein the front side has a reflective surface, wherein the masking layer is adapted to block light from penetrating the masking layer and reaching the first traffic message and reflecting off the reflective surface; and

applying a top sign layer to a surface of the sign substrate, wherein applying the top sign layer to the surface of the sign substrate includes applying the top sign layer to a back side of the sign substrate, and turning the sign substrate around so that the top sign layer is facing in an operable direction.

12. The method of claim 11, further comprising forming the foil from aluminum.

13. The method of claim 11, wherein applying a masking layer includes laminating the masking layer over the first traffic message.

14. A method comprising:

applying a masking layer over a first traffic message disposed on a reflective traffic sign that has a sign substrate having a front and back side, wherein the front side includes a reflective surface and wherein the masking layer includes an adhesive pre-applied on one side thereof, wherein the masking layer is adapted to block light from penetrating the masking layer and reaching the reflective surface and the first traffic message; and

applying a top sign layer to the back side of the sign substrate, wherein applying the top sign layer to the back side of the sign substrate includes turning the sign substrate around so that the top sign layer is facing in an operable direction.

15. The method of claim 14, further comprising forming the foil from aluminum.

16. The method of claim 14, further comprising forming the masking layer from zinc.

17. The method of claim 14, wherein applying a masking layer includes laminating the masking layer over the first traffic message.

18. A method comprising:

applying a masking layer, that includes an adhesive pre-applied to the masking layer, over a first traffic message disposed on a reflective traffic sign that has a sign substrate having a front and back side, wherein the front side has a reflective surface, wherein the masking layer is adapted to block light from penetrating the masking layer and reaching the first traffic message and reflecting off the reflective surface; and

applying a top sign layer to the back side of the sign substrate, wherein applying the top sign layer to the back side of the sign substrate includes turning the sign substrate around so that the top sign layer is facing in an operable direction.

19. A method comprising:

pre-applying an adhesive to a making layer;

applying the masking layer over a first traffic message disposed on a reflective traffic sign that has a sign substrate having a front and back side, wherein the front side includes a reflective surface and wherein the masking layer includes an adhesive pre-applied on one side thereof, wherein the masking layer is adapted to block light from penetrating the masking layer and reaching the reflective surface and the first traffic message; and

applying a top sign layer to the back side of the sign substrate, wherein applying the top sign layer to the back side of the sign substrate includes turning the sign substrate around so that the top sign layer is facing in an operable direction.

20. The method of claim 19, wherein applying the masking layer includes applying a foil.
