Abstract
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.
