U.S. Currency - How Money is Made.
BEP banknote designers develop the overall look, layout, and artistic details of U.S. paper currency.
Engravers engrave a web of fine lines and grooves into steel dies, transforming designers' models into three-dimensional engravings.
In simplest terms, siderography is the means by which multiple images of the hand-engraved die are transferred to a printing plate.
4) Plate Making
The plastic master plates are transferred from siderography and used by plate makers to create hundreds of identical printing plates — identical because they are all based on the same master.
5) Paper & Ink
The paper and ink used in the production of U.S. paper currency is as distinct as its design.
6) Offset Printing
With the introduction of the redesigned $20s in 2003, subtle background colors were added to the currency to enhance the security. For these denominations, offset printing is the first printing that occurs on the "blank" paper.
7) Plate Printing
In the plate printing process, ink is applied to a plate so that it remains only in the engraved areas.
In order to ensure only the highest quality sheets move to the numbering operation, sheets are thoroughly examined using state-of-the-art computer technology.
The acronym COPE stands for Currency Overprinting Processing Equipment. COPE presses in this section utilize the letter press printing process which is the third and final type of printing utilized by BEP for paper currency.
The BEP refers to the process as “LEPE,” which stands for Large Examining Printing Equipment. The LEPE acronym is a BEP label, and not an industry name. LEPE machines are state-of-the-art equipment, specicially designed for the BEP, that consolidate four currency production processes.
Packaging Operations is the final stage of the 32-subject currency production process before the currency is shipped to BEP's customer, the Federal Reserve.
PAPER IS PAPER, GOLD IS GOLD.
