About the project
The Siren’s Call Note brings together some of the most advanced security technologies available today and weaves them into an immersive visual narrative inspired by Homer’s timeless tale.
Each technology uncovers a new dimension of the narrative.
The story comes from Book XII of the Odyssey. In daylight, Odysseus’ galley braves the sea beneath Poseidon’s trident. Under ultraviolet light, a burning sunrise and the face of a siren rise out of the same print.

Seprinto & Partners’ contribution
Innovating, Integrating and Sharing Knowledge
Coordinating the graphic development of the Siren’s Call Note, Seprinto & Partners brought together artistic direction and technical integration to turn a collaborative concept into a coherent demonstration note.
LLS-Luna®, our patented variable-depth Shablon technology for intaglio printing, sharpens fine-detail reproduction while reducing ink consumption.
This expertise is also shared: the Seprinto Academy trains operators, technicians and production managers to master security printing technologies from the ground up.
Cooperating partners
