A method and associated system for authentication, including irradiating an item including a polymer security thread including a polymer material and a doping material within the polymer material and configured to produce a radiation spectrum in response to the irradiating, the doping material capable of absorbing, scattering, or emitting radiation, and detecting the produced radiation spectrum to confirm the presence of the polymer security thread.

An intaglio printing ink includes capsule luminescent pigments and a further machine-readable feature substance. The capsule luminescent pigments include at least one core with a luminescent substance and one shell encapsulating the at least one core. They are characterized by their high luminescence intensity and high chemical stability, which enables a simultaneous loading of the intaglio printing ink with a further machine-readable feature. A printing method and a printed product include the intaglio printing ink.
