“Bulletproof Ink” is a term that may be a perpetually changing measure. As Noodler’s developed greater durability in its inks, the definition of “bulletproof” evolved to accommodate new durability. When first described in Greg Clark’s “Ink Sampler” magazine many years ago it generally referenced water resistance and some other archival qualities. Later the term evolved to include resistance to an increasing array of industrial solvents and bleaching agents and other tools of the forgers – and severe tests in the Arizona sunlight over many months (as well as heat lamps, ageing ovens, biological attacks in moist conditions – Hurricane Katrina situations for example – among many further tests…).

“Eternal Ink” is a marketing term that dates back almost to the early post-Civil War era, a reference to both ink and pen durability back then among several manufacturers…it almost always means the same as “bulletproof” in the Noodler’s Ink line today. Some inks resist bleaching less than others and may be described as “Eternal” more so than “Bulletproof” on some labels (one may resist until all print is gone and the pulp of the paper itself dissolves away, another might last a few hours and change color – but not to the point of the paper dissolving, etc…) – but as is notable on one of the most durable Noodler’s Inks – BOTH terms are used upon the standard black label. In fighting the tools of the forger using a security document (one that has features such as water marks and numerical security lines) – both terms are equally powerful.
