Polymeric substrate and a method of providing same

1. A method of providing a polymeric substrate, comprising

providing a protection system of one or more layers on at least one first surface of the polymeric substrate;

coating a spectrally controlling system having a first transmissivity on a surface of the protection system to provide an external surface, the spectrally controlling system comprising at least a light absorbing or a light reflecting layer;

partially removing the spectrally controlling system from the external surface until reaching the surface of the protection system creating in the spectrally controlling system an area free of the light absorbing or light reflecting layer of the spectrally controlling system; and

filling the area by depositing at least one or more substances in droplets having a second transmissivity of 0% or greater, the second transmissivity differing from the first transmissivity, the external surface comprising a surface of the droplets.

2. The method according to claim 1 , wherein the one or more layers of the protection system comprises an abrasion resistant coating including at least one of a thermal hardcoat, a stress resistant coating, and a SiO 2 layer.

3. The method according to claim 1 , wherein the polymeric substrate, the protection system, and the spectrally controlling system are at least in part permeable to light originating from at least one second side of the substrate.

4. The method according to claim 1 , wherein the light absorbing layer of the spectrally controlling system comprises a chromium-based reflective coating.

5. The method according to claim 1 , wherein the spectrally controlling system is a multilayer physical vapor deposition (PVD) coating using magnetron sputtering incorporating chrome followed by plasma enhanced chemical vapor deposition PE-CVD) of hexamethyldisiloxane (HMDSO).

6. The method according to claim 2 , wherein the thermal hardcoat of the protection system is of thermally cured silicone.

7. The method according to claim 1 , wherein the protection system is applied by dip coating to the polymeric substrate.

8. The method according to claim 1 , wherein the removal of the spectrally controlling system is at a depth of the area compared to the external surface of not more than 220 nm and at least 20 nm.

9. The method according to claim 1 , wherein the spectrally controlling system is partially removed from the protection system by laser etching with a laser.

10. The method according to claim 1 , wherein the depositing is a printing with a device for at least one or more substances in droplets.

11. The method according to claim 10 , wherein the droplets have a volume of less than 50 picolitres and at least 5 picolitres.

12. The method according to claim 10 , wherein the device for depositing at least one or more substances in droplets comprises a jet.

13. The method according to claim 10 , wherein the one or more substances is at least one of a paint, an ink, or a varnish.

14. The method according to claim 1 , further comprising applying a layer of a varnish to a surface of the spectrally controlling system.

15. The method according to claim 14 , wherein the at least one first surface of the polymeric substrate has at least partially a 3D geometry and the area is located at least partially at such a 3D geometry of the polymeric substrate.
