Abstract

The invention is directed to a method of generating a topographic structure or a plurality of topographic structures developed out of or within a surface of an uncoated or a plastic substrate coated with a hard coat comprising the following steps: (a) providing a plastic substrate based on a plastic material having a front surface and a back surface, said plastic substrate being an uncoated plastic substrate or a plastic substrate coated with a hard coat, said hard coat covering at least one of said front surface and back surface; (b) depositing on at least one of said front surface and back surface droplet of a structuring ink; (c) irradiating said droplets of structuring ink deposited on at least one of said front surface and back surface; (d) removing said deposited droplets after having been irradiated and providing a topographic structure or a plurality of topographic structures developed out of or within said at least one of said front surface and back surface of said uncoated plastic substrate or plastic substrate coated with a hard coat. The invention also directed to a plastic substrate based on a plastic material having a front surface and a back surface, said plastic substrate being an uncoated plastic substrate or a plastic substrate coated with a hard coat, said hard coat covering at least one of said front surface and back surface, wherein a topographic structure or plurality of topographic structures is/are developed out of or within a surface of said plastic material of the uncoated plastic substrate or developed out of or within said hard coat of said coated plastic substrate.
