A method for making a plastic film having a three-dimensionally structured and colored surface includes the steps of: providing the film with a three-dimensional surface structure via a shaping process; determining the provided topography of the film surface via a scanning process; and, applying a coloring to the surface after the topography of the surface has been determined. A device configured to apply the coloring to the surface is controlled such that the application of the coloring to the surface is changeable in dependence upon at least one of topological data of the surface and macroscopic shapes of the surface.

Method for making a colored plastic film

A method for producing three-dimensionally structured surfaces of objects, the object surface being created as a reproduction of a three-dimensionally structured original surface with the aid of a machining tool. Accordingly, the topology of the original surface is first determined, a measured depth value being assigned to each surface or grid element, creating a depth map of the original surface. The depth values are evaluated in terms of their influence on the reflective properties of the surface elements and the reflective properties are stored in the form of parameters. The depth values are then modified in accordance with the reflective values and are used as topological data for the electronic control of a machining tool.

Method for producing three-dimensionally structured surfaces

A method allows analyzing and describing the reflective properties of a three-dimensionally structured original surface. The topology of the original surface is determined and the topological data are stored in the form of a depth map in a first data record and evaluated with respect to the influence of the data on the reflective properties. Each surface element is assigned a reflective value in accordance with the evaluation and the value is stored in a second data record and made available to other machining or inspection systems. There, the reflection values of the second data record are divided into classes and the depth values of the first data record, assigned to the classified reflection values, are varied in accordance with the classification. Finally, the changed depth values are employed as parameters for electronically controlling a tool in order to machine the artificially produced surface.
