Flexographic security ink with near infrared fluorophores |
| 摘要 |
<p>Flexographic inks which contain colorants and near infrared fluorescent compounds provide printed documents with colored print, including black, and NIRF security. Printing systems of a combination of flexographic inks enable any color to be printed with NIRF security. Printing methods enable pigments with high infrared absorption to be used in inks where printed in screen format.</p> |
