The pattern may be arise from differences in the microstructure of the web. The nonwoven material may have an embossed pattern having a basic, static component and a dynamic component which varies within a given length of the nonwoven web. Further, a method is provided for obtaining information from a nonwoven web, comprising observing the web surface using an optical reading device, collecting data based on differences in optical properties in the web surface, storing in a digital memory a pattern based on the collected data and comparing the stored pattern to a collection of previously stored patterns.
