In order to admit a structure in negative relief into a metal surface, Accurate Textures applies the traditional and repeatedly tried and established etching technique. 

The etching process is carried out with acids prepared specifically for this purpose by placing tools or tool components to an acid bath or alternatively spraying acid directly onto the tool contour! The length of the reaction time determines the etching depth. Many structures are created by more than just etching. Only through a combination of various etching steps and films is Accurate Textures able to achieve the desired surface structure.
