The presentation will educate attendees about the vital role that color theory and analysis play in high-security printing. By going back to the basics, this session will cover the challenges of color reproduction in security documents, focusing on colors that are hard for digital printers and photocopiers to replicate. By using visual demonstrations of photocopied documents and comparing them to genuine ones, the presenters will highlight the differences in color accuracy. The presentation will also explore limitations of digital and photocopying technology in replicating intricate color shifts and patterns. Finally, the session will conclude with real-world applications and examples of how these colors are strategically used to prevent counterfeiting in secure documents such as passports, ID cards, and currency.
