The Marking Inks Division of Independent Ink was established in 1939 as a subcontractor of specialty inks used by government and military applications. Our trademark 73x® marking inks have unique and proprietary adhesive characteristics that allow for permanent markings even when subjected to years of direct sunlight, solvent abrasion and chemical exposure.

Independent Ink may be best known for its series of marking inks that were developed specifically for use on the NASA manned spacecraft. These inks incorporated a unique feature, which did not outgas thus keeping the air quality of the space capsules safe to breath for the astronauts. Currently, our links are prominently displayed at the Smithsonian National Air & Space Museum in Washington D.C.

Our Marking Inks Division is the preferred provider to the world’s leading aircraft manufacturers – both commercial and military – for their parts marking, and our marking ink is on virtually every specification for military, ordinance, tanks/land-craft, equipment and transport apparatus.

In addition, our Marking Inks Division has been instrumental in the development of custom ink formulations used by the Department of Treasury, INS, Homeland Security, government printing services and foreign currency printing operations. In 1996 our Anti-counterfeit Identification and Authentication Section (AIAS) was folded into the Marking Inks Division to complement the development expertise associated with custom packaging for cosmetic, pharmaceutical, electronics, software and other specialty applications.
