Abstract
Official abstract text for this publication.
A method is provided for creation of a substrate fluorescence mask having background color(s), UV mark color(s), and distraction color(s), to be printed as an image on a substrate containing optical brightening agents. The method includes selecting one or more UV mark colors for the mask such that the UV mark colors exhibit low contrast against the background color(s) under normal illumination and high contrast against the background color(s) under UV illumination. One or more distraction colors are also selected, such that the distraction color(s) exhibit low contrast against the background color(s) under UV illumination and exhibit high contrast against the background color(s) under normal illumination. A distraction pattern, formed from one or more distraction colors, is also selected.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for printing a substrate fluorescence mask on a substrate by a printing device for embedding information in printed documents, comprising: providing a substrate comprising optical brightening agents; receiving an indication from a user of at least one background color for the substrate fluorescence mask; selecting, based on the received indication of at least one background color, at least one UV mark color for the substrate fluorescence mask to…
