Security Device with Chaosmetric Patterns

摘要

Apparatuses of a security device with chaosmetric patterns are disclosed. In one aspect, embodiments of the present disclosure include a security device having a physical surface having formed thereon a composite pattern. The composite pattern can be created from overlap of the imprinting of a first halftone pattern and a second halftone pattern. The first halftone pattern can be created from a first basic building block which forms chaosmetric artifacts in the physical surface upon printing.
