Rupiah banknotes that were used, were not made in an easy way. It takes a lot of process to make paper money for good quality and meet the specifications.
Perum Peruri is the only company capable and authorized by Bank Indonesia (BI) to print genuine banknotes. How is the process?
In one of the industrial areas in Karawang, precisely Parung Mulya village, there is a factory area of 202 hectares. That factory is the mint-money maker now. In total, there are 45 machines that make money in this division.
Head of Money Production Division Peruri, Slamet Haryono explained, the beginning of the manufacture of paper money is from the process of engraving. This is a process that includes design and drawing. The process is done by Peruri with the recommendation of the picture given by BI.
To make the design alone, it takes 2-3 months, because the image is in the process of engraving it is not just any image, but the image is made from pure lines made using the computer.
Process in making money:
Offset printing is the process of printing, like the screen printing on both sides of paper money with the basic color of the money. After offset printing, continued intaglio printing process, which is a refinement process of offset printing. Here, one machine will print the hologram color on the money.
The intaglio printing process is more complicated than offset printing, because one machine runs only one side of a bill, unlike offsets that can work on both sides at once.
“Intaglio was 2 times offset,” he said.
The two processes can not be done simultaneously. Because they have to wait for dry ink so that the color is not faded or dirty.
Following the process, money printing continues into the storage and inspection process. Well, in the process of this inspection will be known where the money is worthy or not. Unsafe circulation is usually due to uneven inks, imperfect coloring or folded papers. The money will be marked and bundled in order not to circulate.
“The failing rate is 10%,” he said.
After that, the next process is the process of numbering, or giving a number on the money that has been printed, then back again done the inspection, when there are money-money wrong print serial number.
The banknotes through the process are still bilyet with prints in large paper, about two pages of newspaper, or 45 sheets of paper money.
After the process, then the money is still in the form of large sheets of paper were cut into pieces using the machine and compiled and packed.
“Then after that manual finishing and packaging,” he said.
Peruri’s finishing manual is performed by Peruri employees who are tasked with checking, compiling, and stacking the paper money to be ready to be sent to BI, including the failed money. From the whole, it can take up to 6 days to complete the process.
Raw materials in the form of special paper obtained only from BI. So that money print can not be added or reduced. Therefore, money that fails production must be sent to BI. This year, Peruri will be printing paper money as much as 9.3 billion bilyets or pieces of various fractions.…
