Abstract
A polymeric substrate and a method of providing same includes providing a protection system of one or more layers on at least one first surface of the polymeric substrate, coating a spectrally controlling system 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 at least one first 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 covering the area by depositing at least one or more substances in droplets.
