Document Security

This technology has been used worldwide by government agencies, major corporations, and various industry associations to protect passports, national ID cards, driver’s licenses, birth certificates, tax receipts, bond certificates, trip permits, currencies, stamps, legal documents, digital documents. Through all of these applications, for more than 25 years, we have maintained the top level of security, reliability and customers’ satisfaction.

We offer products to protect the preprinted design of all security documents. Our SI® hidden images can be imbedded into the existing artwork, or they can be added as a separate security layer. They can be reliably printed using almost any printing technology: digital, etching, flexography, gravure, holography, intaglio, letterpress, lithography, silkscreen.
