Elevating Security Documents: Next-Generation Micro Perforation

In an era where counterfeiters use highly sophisticated technology, security printing must constantly evolve. So said Thorsten Tritschler, Managing Director of Zeiser, a German pioneer in security technology founded in 1956 that stands at the forefront of this battle, in his presentation at the recent HSP Latin America conference in Guatemala.

Operating under parent company Orell Füssli, Zeiser’s expertise covers five critical dimensions of security fabrication: mechanical impact numbering, digital inkjet serialisation, camera-based inspection, controller integration, and identification track-and-trace systems.

These core competencies – supported by service hubs across the US, UK, Argentina and Colombia – safeguard critical global documents, including banknotes, passports, tax labels, lottery tickets, and more.

The mechanics of micro perforation 

A core highlight of modern security design is micro-perforation. This process creates extremely small, laser-etched patterns directly into a document’s substrate. Unlike traditional security methods that require specialty inks, micro-perforation requires absolutely zero consumables. The resulting patterns remain invisible under normal lighting conditions but reveal intricate designs when held against a standard light.
