The teachings as provided herein relate to a watermark embedded in an image that has the property of being relatively indecipherable under normal light, and yet decipherable under UV light. This fluorescent mark comprises a substrate containing optical brightening agents, and a first colorant mixture pattern printed as an image upon the substrate. The colorant mixture pattern layer has as characteristics a property of strongly suppressing substrate fluorescence, as well as a property of low contrast under normal illumination against the substrate or a second colorant mixture pattern printed in close spatial proximity to the first colorant mixture pattern. The second colorant mixture pattern having a property of providing a differing level of substrate fluorescence suppression from the first such that the resultant image rendered substrate suitably exposed to an ultra-violet light source, will yield a discernable image evident as a fluorescent mark.
