Graphics of the Americas Provides Attendees with Counterfeiting Protection Tips

3. Co-founder of Opalux Inc., Dr. Andre C. Arsenault, presented what the company says is a new and unique approach to photonic crystal security imaging applications, using Opalux's core technology products, P-Ink™ and Elastink™. These Opalux inks contain nanometer-size opal crystals that can be tuned to refract visible light into selected wavelengths of desired colors. The P-Ink and Elastink can change color, reversibly or irreversibly, by being activated electronically, mechanically or thermally; thus acting, the company says, as excellent counterfeit and knockoff deterrents for security packages, labels and documents.
