How To Produce "Grandpa Mao" In His Wallet

From the present open process, there are at least 13 steps in the printing process of RMB: designing banknote, printing paper quality inspection, making block printing, making printing plate, offset printing, concave and convex plate printing, printing number, checking large banknote, cutting sheet, checking single note, statistical quantity, packing box, and sending the Treasury.

The paper detection link is carried out on a large light box.

With the help of light, this part will not only check the quality of banknote paper, but also choose the paper maker to stack the paper in the direction of watermark and punch holes on the side with punching machine.

It is very important to unify the watermark direction of the paper. If there is a mistake, the watermark inversion will appear in the process of batch printing.

Waste coins are of great value in banknote lovers.

However, the value of this collection comes from the low probability that the waste money flows into the market.

In the process of strict quality inspection, there is almost no chance for waste coins to flow into the market.

Do not believe? The older generation of money printing workers may not even know their specific work content.

The work unit is also a series of confused numbers.

For example, the printing workers of Shanghai printing plant are filling the 542 factories.

When entering a banknote printing factory, entry and baptism is a study of confidentiality regulations: no other teams in the workshop are allowed to go to the door, and do not disclose to the outside world the work of printing money factories and their own work.

All the terms are thoroughly cooked in the chest.

The people at the front line of banknote printing always keep silent, and the process of printing money is always wearing a mysterious veil.

Until the Beijing banknote printing plant and Shanghai printing factory had lost the number of "541 factories" and "542 factories", the large square printed the signs of banknote printing plants at the door, and the manufacturing process of RMB was gradually unveiled.

Shanghai banknote printing factory.

The printing of Renminbi is completed by the 11 companies affiliated to China Banknote Printing and Minting company, and the former is directly managed by the central bank.

The 11 enterprises include three banknote paper factories, namely Hebei Baoding banknote paper mill, Jiangsu Kunshan banknote paper mill and Chengdu banknote paper mill.

Do not belittle these three banknote mills. Oh, banknote paper is not ordinary paper.

It is a special paper specially developed. Besides the features of wear-resistance, folding resistance, acid resistance and alkali resistance, it is covered with

。

When printing banknote paper is sent to banknote printing plant, the printing process of RMB will really start.

In the process of banknote printing, trial run printing is one of the key processes. It has strict confidentiality and management system. It also controls the selection and quantity of paper strictly.

These banknotes produced during the trial run are trial tickets.

According to the regulations, the test tickets must be centralized and destroyed.

However, some of the test tickets are out of the market or collected by various banknote collectors.

The printed renminbi is a large edition of banknote, which is about the same size as the people's daily.

After that, they will be sent to the sealing hall for quality inspection.

First, quality inspection needs to confirm whether the color is accurate, whether there are breakage, and whether there is a problem of missing printing.

Through this quality inspection link,

"Will enter the next process: cutting.

At this point, these bills became independent and became the look of banknotes that we usually saw.

Next, the second wave.

Then came, this link needs more manpower for more detailed inspection.

The quality inspector will check the number, text, watermark direction, whether the pattern is clear, whether the banknote has wrinkles, whether the size is up to standard or not.

In the sealing hall, a quality inspection worker can complete tens of thousands of RMB quality inspection every day.

In this process, if someone fails to check carefully, turn over several sheets at once, once they are found, they will be recorded.

At this time, naughty, you will say, how can it be found that you have stolen a lazy person? Actually, in order to ensure that any time in the process of making money is left behind, every workshop in the banknote printing factory has installed an uninterrupted HD camera system for 24 hours.

It is said that the monitoring system can achieve full coverage of every corner of the printing shop, so that everything that happens at any time and place can be adjusted from computer records.

In the end, the QC qualified Renminbi should be counted again, and it can be boxed to the central bank's "Treasury" after everything is ready.

And only when they enter the circulation link can they become "money" from the "products" of the printing press.

The waste coins will also be eliminated in the "check sheet note" link, and will be submitted to the registration and examination on the basis of the principle of "handling the number of hands" and "how much to get out", and the probability of inflow into the market is almost zero.

There are several kinds of common waste coins, such as watermark variants, trimming, shifting, overprinting, overprinting (repeat printing), blanking (printing process with foreign objects blocking, leaving blank), sticky printing (ink is not dry paper sticky, inverted inverted light text).
