Substrate fluorescence pattern mask for embedding information in printed documents

A fluorescent mark indicator comprising:

• a substrate, including:
• an optical brightening agent,
• an image rendered on the substrate including a repeating pattern formed from a first colorant combination in mosaic combination with a second colorant combination, and
• a background rendered on the substrate including a repeating pattern formed from a third colorant combination in mosaic combination with a fourth colorant combination;
• wherein each of the first, second, third, and fourth colorant combinations is formed from non-fluorescing printing materials;
• wherein the first and third colorant combinations are a same visual color under normal illumination and the second and fourth colorant combinations are a same visual color under normal illumination;
• wherein the first and second colorant combinations are a different visual color under normal illumination and the third and fourth colorant combinations are a different visual color under normal illumination;
• wherein the first and second patterns have a dissimilar radiated fluorescence under a UV light based on one of the first or second patterns suppressing a radiated fluorescing of the substrate and a remaining of the first and second patterns reflecting light fluorescing off of the substrate as an authenticating mark.

A system for creating a fluorescence mark comprising:

• a substrate, including:
• an optical brightening agent,
• an image rendered on the substrate including a first metameric pattern formed from a first colorant combination alternating with a second colorant combination, and
• a background rendered on the substrate including a second metameric pattern formed from the first colorant combination alternating with a third colorant combination;
• wherein each of the first, second, and third colorant combinations is formed from non-fluorescing printing materials;
• wherein the second and third colorant combinations are a same visual color under normal illumination;
• wherein the first and second colorant combinations are a different visual color under normal illumination and the first and third colorant combinations are a different visual color under normal illumination;
• wherein the first and second patterns have a dissimilar radiated fluorescence under a UV light based on one of the first or second patterns suppressing a radiated fluorescing of the substrate and a remaining of the first and second patterns reflecting light fluorescing off of the substrate as an authenticating mark.
