From Cotton To Banknotes, What Kind Of Process Will It Go Through?

You use money every day, but do you know how the money is produced?

Today, Xiaobian shows you how cotton is pformed into cash step by step.

From cotton to banknote paper, there are two processes of beating and papermaking.

The armed police stationed at the gate of the banknote company, where guns are tightly held, have strict security measures.

After the application for approval and temporary handbags and mobile phones, reporters were allowed to enter the production workshop.

In a moment, silence is replaced by the roaring of machines.

In the workshop, workers wearing blue fixtures are busy orderly.

After the process of multi banknote printing and drying, inspection and so on, a piece of snowy white banknote paper has changed into a red and green banknote. It takes about 1 months before and after the whole process.

Printing paper, which looks like "white paper", has been added to the process of making paper.

As the first process, offset printing is a kind of lithographic printing. Although this technology is widely used in other industries,

Its accuracy is higher.

Reporters at the scene saw a piece of snow white paper printed into the offset press, printed by ink, with various shades, printed with the dome of the hall of auditorium of the Great Hall of the people, and decorative patterns from ancient bronzes.

[offset printing process, the first process of RMB production.]

In fact, in daily life, people often distinguish the authenticity of the banknote by touching the president's head and national emblem. If the hand is a Zhen Zhang note, the fingertips will feel a pronounced concave and convex feeling, and the distinctive concave and convex feeling of the genuine banknote comes from the unique printing method of the renminbi, gravure printing.

The ink flavor beside gravure press is more intense than that in other areas, and the "product" pattern from its "mouth" is three-dimensional and hierarchical.

In the banknote printing industry, there has been a saying that "no coin can not be formed". Until now, gravure printing is still an indispensable means of anti-counterfeiting in banknotes all over the world.

[gravure printing, gravure printing and other processes, gravure printing printed text has a very obvious sense of concave and convex].

In addition, there is a row of numeric codes on the lower left side of each banknote, which is the crown number of the renminbi, and the process of printing the crown is called the seal code.

The key word number is composed of alphabetic alphabet and Arabia number, which is used to mark printing batch and order.

The staff said that the number of each banknote is just like the ID card number, which is unique.

The printing code embodies the digital management in the banknote printing industry and is convenient for tracing.

"The smell in this room should be what you call the smell of copper."

With a large version of banknote printing paper, a staff member laughed.

"In our eyes, this is the fragrance of ink."

The main ingredients of banknote paper are

In the banknote workshop, a worker took out a large piece of banknote paper and gently shook it, making it clear and clear. It was completely different from the sound of ordinary white paper.

It is understood that this is because the particularity of the renminbi is quite different from the ordinary paper from the source of banknote paper.

The main components of plain paper are wood and grass fiber, and the main components of banknote paper are cotton or linen fibers.

The staff told reporters that from cotton to banknote paper roughly need beating and paper making two processes.

"Every banknote has a watermark pattern. When you look through the light, you can see clearly the shapes, figures and characters of the dark and dark texture."

The staff said that the watermark was not added in the later stage, and it was formed in the process of papermaking.

Not on the surface of the paper, the watermark is "clamped" in the paper.

High temperature and humidity requirements in precision workshop

Banknote printing is a precision production process.

It is understood that the temperature in the printing workshop must be kept in a constant temperature range, because once the temperature is too high or too low, the paper will be deformed and the position of the printed image will be shifted.

A worker examined the finished product carefully.

In the whole process of RMB production, we can find that online and offline quality testing equipment is applied to every machine and every process.

Quality monitoring.

In the gravure printing workshop, Xiao Li, a worker, took a magnifying glass and compared the products spatting out with gravure printing machine with the samples in his hand.

He wants to check a lot of content, whether there are defects, flaws, and so on.

Xiao Li told reporters, "in order to ensure foolproof, we will insist on manual spot checks."

Precision is not only reflected in quality, but also one of the most planned industries in China. The production volume of banknote printing plants should be carried out in line with the central bank's directive plan to meet the needs of distribution.
