Daylight fluo watermarking
Security prints hiding watermarks (texts, logos) that are revealed under the display of a smartphone.
Daylight fluorescent watermarking enables hiding security watermarks within the visual content of a document or of a package. These watermarks remain totally invisible under white illuminations (e.g. daylight, fluorescent tubes, white LEDs). The watermarks can be revealed under a traditional UV-A illumination (black lamp) and also under a blue illumination such as for instance a smartphone displaying a pure blue image.
