How Important Is Durability Of Ink?

[KellyMcJ]

Unless there's some crazy fading that happens when ink is not exposed to light (due to the reaction with paper etc) I don't worry about fading.

 

For general use, I like to have at least some water resistance. It's not a requirement but it's definitely a consideration. I'd rather not lose my writing if I slop or spill something.

 

For my EDC, and for check writing etc, I use Sei Boku (this ink is impervious to everything except maybe fire. Possibly.) It works on just about everything, everywhere, no matter what I need to sign or write on (because when I'm out and about, I don't have a desk full of pens to choose from.) My workplace also requires indellible ink and this stuff is about as indellible as it comes.

My work is not that important....

 

Have music manuscripts written 40 years ago with Sheaffer brown Ink; along with papers written 25 years ago in Waterman brown, they all look fine.

Somewhere in one of the links on one of the fade tests that I did, was an explanation that fade tests are really just a way to speed up the natural process of break down of the ink. One of our chemists will have a better explanation. I can tell you that most roller ball ink fades faster than ball points but the roller ball inks that say that they are fade resistant, often are fade resistant. Black generally holds up better than blue and orange fades quite quickly ----BUT--- BSB is one of the fastest fading FP inks and the one that I use to test my boards. If you want to improve permanence, consider adding Ghost Blue or De Atramentis Dokument Ink thinner to any ink. Neither will change the color of the ink. DeA DIT will make the ink a lot wetter. Noodler's GB may or may not change the wetness. And if you want the ink to last forever use Noodler's KTC - it was the most resilient of the inks we tried at our plant nursery.
