Patent
CA 2564665
An item bearing an image printed with at least one ink that is fluorescent under ultra-violet radiation of specific wavelength is such that the image comprises two partial images, whereby a first partial image in a red fluorescent ink and the second partial image in a green or blue fluorescent ink are arranged as negative images with respect to each other in such a manner that to an observer simultaneously viewing both partial images, each eye individually through a colour filter that is selected for each of the fluorescent colours of both partial images, the partial images appear as a three-dimensional image. A preferred application for the item is for packaging, packing materials, packing aids, bonds or entry tickets with counterfeit-proof and/or optically demanding surface area.
