摘要: A method is provided for creation of a substrate fluorescence mask having background color(s), UV mark and distraction to be printed as an image on containing optical brightening agents. The includes selecting one or more colors the such that exhibit low contrast against color(s) under normal illumination high illumination. One are also selected, pattern, formed from colors, selected.
