I've tried contacting the BEP by email to no avail.. So I'll bring my question here hopefully somebody can help me. Where do they get the ink I guess not where they get it but how do they get it in what form. Specifically speaking for the seals and serial numbers. I know that it's a magnetic ink. But do they get it already in the black and green color? Because it seems like the more cost effective way is to get it in the primary colors and then mix on site. Just like your printer at home..

@keith12 Whether or not they mix the ink on site is not going to crack the code for the best produced counterfeit money lol #128518;

Yeah, doubtful they're not going to tell you anything about it.

@ bobby131313 Yeah they're not going to tell you whether or not they mix the inks to get the color they need for printing or receive the inks already that color. And at the same time put out information about that ink being magnetic and having a different strength of magnetism for each denomination.

I doubt the BEP will give you the formula for their ink (or other security features) but this site has some interesting info on the distribution & printing process of US currency. The link is for their educational videos. Just go to their MENU to discover the other sections/resources about the districts, distribution, etc. https://www.uscurrency.gov/media/videos

The BEP formulates the ink they use to produce U.S. currency "in house" from chemicals procured beforehand. They've been doing this for over a hundred years.

Quote: The BEP formulates the ink they use to produce U.S. currency "in house" from chemicals procured beforehand. That's interesting. The Bundesdruckerei in Berlin, Germany, which is one of two banknote printers here in Germany, recently purchased the ink (not the chemicals to produce the ink) to print €100 banknotes from a Swiss company. By the way, this information is not some kind of ''state secret.'' If you know where to look on the internet you can find such information.

@SteveInTampa cyan, magenta, and yellow are the primary ink colors they are used to make the green color. Are you saying that they mix these three colors together to get the green that they use?

I'm pretty sure it's just the black ink that is magnetic. The coloured ink is not. Quote: @SteveInTampa cyan, magenta, and yellow are the primary ink colors they are used to make the green color. Are you saying that they mix these three colors together to get the green that they use? You can make green dye in a very, very large number of ways, not just by mixing those three colours like in an inkjet printer. Chlorophyll is naturally green, but it degrades in air, so is not really suitable as a dye. Various copper-based, nickel-based and chromium-based compounds are also bright green, and they don't degrade in air; these were used in previous decades, but they can change colour in acid, so aren't considered suitable either. Whatever secret herbs and spices go into the BEP's coloured ink these days, they turn out green - or whatever other colour they're trying to make - and they stay that colour under many different chemical environments. Serial numbers can change colour in enzyme-based detergent, while regular soapy detergents don't have the same effect, so I suspect the green dye is biochemistry-based.
Don't say "infinitely" when you mean "very"; otherwise, you'll have no word left when you want to talk about something really infinite. - C. S. Lewis
