How much ink does the BEP use to print money each day?

The Bureau of Engraving and Printing (BEP) uses approximately 40 tons of ink each year to print U.S. currency, which translates to about 100 gallons of ink per day. The exact amount can vary based on production needs and the types of currency being printed. The BEP utilizes specific ink formulations to ensure durability and security features in the notes.
