Latest Patents
Julien Andres holds a patent for the "Synthesis of authenticable halftone images with non-luminescent halftones illuminated by an adjustable luminescent emissive layer." This patent describes a method and computing system designed to produce an authenticable security device with two sides. The verso side features an adjustable luminescent emissive layer made from invisible luminescent ink halftones, potentially combined with a UV absorbing printed layer. The recto side is covered with transmissive non-luminescent ink halftones. The invention allows for the prediction of backlit colors resulting from the emissions of the luminescent layer or illumination by normal white light through the transmissive non-luminescent ink halftones. This innovative model enables the computation of surface coverages of the ink halftones to achieve desired colors under different lighting conditions.
