Abstract

A method for coating a transparent carrier plate includes coating a backside of the carrier plate with a first chromatic layer, applying a non-opaque metallic blocking foil coating on top of the first chromatic layer, and applying a second chromatic layer on top of the non-opaque metallic blocking foil layer. The method results in a coated carrier plate having increased color intensity and brightness. Further, by varying the hues in the first and second chromatic layers, a resulting hue may be provided that is different from the hue of the first and/or second chromatic layer. In addition, the hues of the first and second chromatic layers may be varied over the surface area of the carrier plate.

Claims

1. A method of manufacturing a colorized plastic carrier plate comprising the following steps:

providing a transparent acrylic plastic carrier plate having a back side;

applying a first chromatic layer to the back side of the transparent carrier plate;

embossing a non-opaque metallic foil layer on top of the first chromatic layer with a roller-type embossing process;

applying a second chromatic layer on top of the metallic foil layer.

2. The method of claim 1 wherein the first chromatic layer is applied using a silkscreening process.

3. The method of claim 1 wherein the first chromatic layer is further characterized as being a chromatic lacquer layer.

4. The method of claim 3 wherein the first chromatic layer is applied by spraying.

5. The method of claim 1 wherein the second chromatic layer is applied using a silkscreening process.

6. The method of claim 1 wherein the first chromatic layer and the second chromatic layer have substantially the same color.

7. The method of claim 1 wherein the first chromatic layer and the second chromatic layer have substantially different colors.

8. The method of claim 1 further comprising the step of selecting a color for the first chromatic layer and selecting a color for the second chromatic layer so that a chromatic impression produced by the first and second chromatic layers and the metallic layer is increased.

9. The method of claim 1 further comprising the step of selecting a color for the first chromatic layer and selecting a color for the second chromatic layer so that the hue produced by the first and second chromatic layers and the metallic layer is different than the hue produced by the first chromatic layer alone.

10. The method of claim 1 wherein the hue of the first chromatic layer is varied across the surface area of the carrier plate.

11. The method of claim 1 wherein the hue of the second chromatic layer is varied across the surface area of the carrier plate.

12. A colorized plastic plate comprising:

a transparent acrylic plastic carrier plate having a back side and a front side and a surface area, the back side of the carrier plate being coated with a first chromatic layer, the first chromatic layer being embossed with a non-opaque metallic foil layer, the metallic foil layer being coated with a second chromatic layer, the colorized plastic plate both transmitting light and reflecting light through the front side of the plastic carrier plate and through the second chromatic layer.

13. The colorized plate of claim 12 wherein the first chromatic layer and the second chromatic layer have substantially the same color.

14. The colorized plate of claim 12 wherein the first chromatic layer and the second chromatic layer have substantially different colors.

15. The colorized plate of claim 12 wherein the hue of the first chromatic layer is varied across the carrier plate.

16. The colorized plate of claim 12 wherein the hue of the second chromatic layer is varied across the carrier plate.

17. The colorized plate of claim 12 wherein the first chromatic layer is applied using a silkscreening process.

18. The colorized plate of claim 12 wherein the second chromatic layer is applied using a silkscreening process.
