An Industrially Applicable Honeycomb Texture

A new method for creating a honeycomb texture has been found. It uses a directly printed inkjet mask and isotropic wet chemical etching through it. A special printing pattern has been designed so that structures smaller than the droplet diameter could be printed. After etching it yields a hexagonal honeycomb texture with etch pits of 23 um depth and a pitch of 50 um. The weighted reflection is 18.4 % and is hence considerably lower than most other honeycomb textures. As inkjet-printing is an already well-established, cheap and fast process this method can be easily established industrially.
