About us

175 years of history

Soon after being founded in 1847 by Mr. Emil Theodor Gleitsmann the company started producing both high-quality standard printing inks and innovative security inks.  The company has been based in Berlin since 1953. In 2023 the French government owned IN Groupe (headquartered in Paris) acquired 100% of the shares of Gleitsmann Security Inks GmbH. The best printers have been protecting their products with high-tech inks from Gleitsmann. The range of top-quality inks covers a wide variety of requirements.
