What is paper money made of?

The texture of banknotes is different from ordinary notes that are used in daily life. Paper money is made of a special blend of cotton and linen fibers; To make it more difficult to counterfeit, this type of paper is usually called cotton paper or rag paper.

The ink used for printing on it is specially made by the engraving and printing office, and this combination is considered very durable for daily use, and it is worth noting that banknotes It is difficult to use it in the illegal trade in cash and money laundering due to its complex industry, which is difficult to imitate completely, and this is what makes it easy to detect if it is forged.

What are the stages of making paper money?

The process of making paper money goes through several stages, and each production process is insured and strictly controlled, and each banknote that is manufactured is included in the total production of printed notes, even those damaged during the manufacturing process.

The following are the stages that banknotes go through during manufacture:

Choosing special paper and ink Choosing the raw materials from which banknotes are made is no less important than the process of their manufacture.

The special mixture of paper consisting of 75% cotton and 25% linen gives the papers the appropriate texture for them, and it contains small parts of red and blue fibers.

As for the inks used in coloring and printing banknotes, they are made up of colored and dry pigments mixed with oils and chemicals that are used to produce thick printing inks. Here came the name of the banknotes (green currency).

In addition to the many checks that take place during the printing process, raw materials also undergo rigorous inspections before they are used, inks are tested for colour, viscosity and other properties, and paper is produced by a single manufacturer in a confidential and tightly controlled process that tests the paper for its chemical composition and thickness and other properties.

Color printing The main printing process is known as intaglio printing, and this process is used because of its ability to produce extremely fine details that remain legible under repeated processing of the sheets, and a stack of 10,000 sheets can be loaded into the high-speed rotary intaglio printing machine at one time, the main printing plate The roller is coated with ink and the squeegee removes ink from the plate surface, leaving only ink stuck in the design recesses engraved on the banknote, then inserts the paper into the printer to pass between the main plate drum and a smooth, hard printing roller under pressure up to 15,000 psi (1034 bar).

Next, the printing roller pushes the paper into the fine lines engraved on the printing plate to pick up the ink leaving an image about 0.0008 inches (0.02 mm) high above the paper. This process is repeated at a rate of 10,000 sheets per hour.

The printed papers are then stacked on top of each other, and the back of The banknote is in green ink first, and allowed to dry for 24-48 hours before printing the front side with black ink.

Printing Pattern, Pictures, Numbers and Letters for each category

The inscription, images and numbers are printed using intaglio printing technology, each of which is printed separately from the other and in order.

For example, the inscription is first printed in a recessed printer and then left for some time until the ink dries completely, then the banknote is transferred to another printer, where the images are printed and then left to dry as well, and the same applies to letters and numbers.

Printing serial numbers and seals

Each banknote has a serial number, this number cannot be found on any other banknote at all. The serial number consists of eleven numbers and letters, and the serial numbers include the year in which this banknote was approved by the Minister of Finance.

As for counterfeit banknotes, the edges of the seals are serrated and differ in their measurements.
