When people get new banknotes from the bank, they never think it has such a complicated experience!
In the past, China's banknote printing industry was very closed. The names of the factories were all code-named, and now the mystery is slowly being unveiled. The brand of "Beijing Banknote Printing Factory" has been hung upright on the door.
And a RMB, from hand-carved template to the factory, has to go through at least ten procedures. While working in a money printing factory, although the eyes are full of banknotes, the production quantity is strictly controlled, and even defective RMB cannot be thrown away at will. It is reasonable for the workers to be so calm.
The task of printing the renminbi was completed by the division of labor of 11 enterprises under the China Banknote Printing and Minting Corporation directly under the leadership of the People's Bank of China. The place where the renminbi is printed is called the banknote printing plant.
The RMB printing process can be divided into the following basic steps: paper detection, pre-press processing and plate making, trial printing, formal printing, quality inspection, cutting, quality inspection, sealing, etc.
The banknote paper used for printing RMB is watermark paper, which is a special paper used for printing banknotes. This paper is produced by three banknote paper mills under the China Banknote Printing and Minting Corporation. They are: Hebei Baoding Banknote Paper Mill, Jiangsu Kunshan Banknote Paper Mill, and Chengdu Banknote Paper Mill. In addition to its physical and chemical properties such as wear resistance, folding resistance, acid resistance, and alkali resistance, it also has built-in security lines, colored red, blue fiber and other anti-counterfeiting means, and it is covered with watermark patterns for anti-counterfeiting.
Before printing, the staff should check the quality of the paper sheet by sheet. Because the watermark has a direction problem, each paper must be stacked in the direction of the watermark pattern and punched on the edge with a punching machine.
Before RMB printing, as with ordinary printing, a printing template must be made. Because graphic anti-counterfeiting is used, when making coin faces, the corresponding design software in the computer should be used to design various subtle and complex anti-counterfeiting patterns, and other related texts and patterns, and output them as film for backup.
The printed RMB will be sent to the sealing workshop. The quality inspection workers will check the quality of each RMB under the light: In the sealing workshop, checking the quality of the RMB is divided into two steps. The first step is to check first. A large sheet is to check a large version of several RMB printed one by one from the printing press. The quality inspection at this time is mainly to check macroscopically whether there are quality problems, such as whether the color is accurate, whether it is damaged, or whether there is any missing print ...
After checking the large sheet, enter the next process: cutting. Cutting is to cut the RMB on the large sheet into small sheets, and then change the RMB into the same size as we usually use; the next step is to check the small RMB, for example: whether the number is printed incorrectly, whether the color is uniform, and whether the watermark is Upside down ...
Then, the banknotes that have been checked are sealed up and shipped to the bank for social circulation.
