Abstract:
A platform of overt digital printed features based on unique and difficult-to-replicate-materials, and custom built printing presses is being developed that shows the promise to fulfill the requirements mentioned above.
These features are based on unique metallic and inorganic fine particles that are made by unique production processes. There are many lab-scale techniques to make similar particles but these lab processes result in agglomerated particles that cannot be printed using high-resolution digital techniques. The particles made by these new-to-world processes have special nano-scale surface modification that result in non-agglomerated, non-agglomerating and non-settling particles useful in ultra-low viscosity digital inks. The particles have inherent security. The chemical nature and size of the particles can result in metallic effects, microprint effects, angle dependent effects and even optically variable color-change effects. And because the particles are inorganic-based, they are more durable that many security features. The effects are obvious, easy to authenticate and durable.
