Pixel watermarks for creative banknote design opportunities
Pixel watermark security features offer new possibilities for developing eye-catching watermark designs that are secure against counterfeiting. The highly contrasting bright three-dimensional effect that is visible when held against the light is very easily authenticated by the public. Pixel watermarks are created during papermaking by varying the thickness of the paper to produce patterns of dark pixel dots on a lighter background.
Due to the complexity of their creation, Pixel watermarks are extremely difficult to counterfeit, resulting in only poor quality print copies of watermarks. Pixel watermarks provide new opportunities for creating attractive watermarks that more closely reflect the fine detail of, for example, a portrait from an original artist’s design. Additionally, contrasting pixel watermark elements showing perspective with a standard multitone watermark within a design can be particularly striking and effective.
