Chapter 280 Anti-counterfeiting
Lengxiang Garden, in the Shuiyun Pavilion.
Jiang Xueying was sitting side by side at the desk with Ma Xianglan, discussing something intently.
Qiao Qiao sat aside bored and couldn't help but be overjoyed when she saw Zhao Hao coming in.
Just as she was about to speak, Zhao Hao put his finger on his lips and signaled Qiaoqiao not to disturb the two of them.
He tiptoed over, stood behind the two of them, and listened to their serious discussion.
It smells quite nice.
Uh, Mr. Zhao refers to the seven or eight different style tickets on the table, as well as the extinct Daming Baochao on the market.
Well, the taste of money is nothing else.
"In fact, over the years of operating a money shop, Wu Ji has accumulated a set of anti-counterfeiting methods, such as watermarks, micro-carved seals, etc.."
Jiang Xueying used her slender fingers to pinch a ticket for Wu Ji, and the yellow oriole came out of the valley and explained:
"You see, the Wu Ji Club ticket is in the middle of the circle, and you can see the blank space in the circle, but when you raise it to the light, you can see five connected peaks. This is our Wu Ji's 'Watermark Dark Note'."
"How did this be printed?" Ma Xianglan asked curiously.
"I heard that when making paper, the thickness of the pulp is changed through the changes of the wire mesh." Jiang Xueying explained: "And there are also secret notes on the fonts and patterns on the watermarks, and the money shop can tell the truth at a glance."
As she said that, she pointed to the red seal on the lower right corner of the ticket. "As for the micro-carved seal, my sister is proficient in calligraphy and painting, so I don't need to explain it."
"Yeah." Ma Xianglan nodded. The content of the micro-carved seal was a poem of hundreds of words. It was carved very finely and could not be carved by ordinary technology.
Because the content is too complex and detailed, even the original carving can no longer carve out the micro-carved seals that are exactly the same as before.
Moreover, the money house will deliberately leave some difficult-to-observe flaws when carving, which will make it even more difficult to forge.
"But it is too difficult for ordinary people to distinguish. So you still have to work harder in a more intuitive place."
Jiang Xue greeted and said, "For example, our Wu Ji uses special hemp paper. The formula is the top secret of the money shop. Only three or five people know it. The same is true for ink."
Then she picked up the Wanyuan ticket and said, "This is the best ticket on the market today. It uses special formula Sichuan paper, and there is a red grid and green line printed on it. It is not only beautiful, but more importantly, it is difficult to forge it."
"Yes." Secretary Ma nodded, and put his fingers on his nose, which became smaller and smaller glasses on his nose, and his voice softly said:
"Two-color overprinting is not difficult, we can do it in our own printing workshop."
"We can't just satisfy the two-color overprinting, but also have to do the three-color overprinting." Zhao Hao smiled and said.
"Brother is back?" If someone else was afraid of him, Jiang Xueying and Ma Xianglan, who were calm in the face of change, were very calm.
"Young master, please change people. Sister Xueying insists on making the best quality silver notes." Ma Xianglan stood up and gave Zhao Hao a place, and couldn't help but smile bitterly: "How can I understand this? You decide, I will draw as you said."
Not only can Sister Ma hide her weakness, but she also shows weakness. Her rank is much higher than Jiang Xueying. Even President Jiang, who is keen and keen, can't tell that she is a foreigner, and she also regards Sister Ma as a good friend of the Ming Dynasty.
Zhao Hao sat on Ma Xianglan's chair and smiled and said, "Xueying is right. Our silver bills are not accepted by the name, we do not recognize people, and we pay the silver bills as soon as we see them. The anti-counterfeiting requirements are much higher than those of the general tickets."
"Yes, you can recognize votes and people. If you have reserved seals and secret seals, it is enough for people to forge them." Jiang Xueying nodded and said distressedly:
"But if our banknotes are not circulated by banks, most of the methods are not used, so we can only work hard to print the banknotes."
The seal and secret seal on the ticket must be passed through the bank and verified with the reserved information to distinguish the authenticity. How can ordinary people outside the bank do it?
If the banknotes want to play the role Zhao Hao expected, it must overcome this problem and allow ordinary people to distinguish the authenticity of the banknotes.
There are not too many fake masters in Jiangnan. Even "Along the River During the Qingming Festival" can be made into fakes, not to mention a small silver note?
We will not let the fake masters be discouraged and dispel the idea of fake. I believe that countless fake silver notes will soon flow into the market.
The common people could not receive every silver note, so they went to the bank to check the authenticity. When they turned around, they found that they had received fake silver notes that could not be exchanged for silver, and they would definitely be furious.
If there are too many such things, who dares to check cashiers and use silver notes in daily trading?
In this way, the bank notes of Jiangnan Bank will lose their monetary attributes and return to the level of "drawal notes". What is the difference between them and the meeting ticket?
If you can't satisfy your dream of printing money, what bank will Mr. Zhao open?
~~
"Don't worry, sister. We should scientifically prevent counterfeiting and no one can imitate it." Mr. Zhao was convinced and took out a few pieces of white paper from his arms while speaking, and placed it on the table.
He had never been worried about his body, and even had to hold his handkerchiefs and sunglasses, but he put the papers on his body, which showed his treasure.
The two girls quickly looked at the paper carefully, and even Qiaoqiao joined in the fun to pick up one, and couldn't help but exclaim: "It feels so good, it's very shaved."
Jiang Xueying also nodded and said, "It's really tough."
As she said that, she even folded it, but there were no creases.
"Let's see if you're going to tear it up again." Zhao Hao said with a smile again.
Ma Xianglan twisted the ends of the paper and tore it away, but it took a lot of effort to pull it away and deform it.
"I can't even tear it apart. How did this paper be made?"
Mr. Zhao smiled sly and said, "This is a company secret."
He asked Qiaoqiao to bring the basin over and soak the paper in the water.
As a result, the paper was soaked for a long time and the paper was not deformed or damaged.
Finally, Mr. Zhao took out the lamp and burned a piece of paper. As a result, it only smoked and coke, but no fire appeared...
"I believe that no one can imitate this kind of paper within decades." Mr. Zhao asked with a smile: "It should be the best way to use printing silver notes."
Of course it is appropriate. Because this is the printing paper of RMB four hundred years later.
Unlike using bamboo and wood pulp to make paper at this time, only half of the raw materials for printing money paper are used for wood pulp, and the remaining 90% are cotton velvets.
Cotton velvet is also called "cotton seed velvet", which is the remaining fibers on the wool cotton seeds after cotton ginning.
Because nutrients are easier to transport into velvets, the content of cotton velvet cellulose is far greater than that of normal lints. Therefore, it is very tough to make paper, and it is difficult to tear and pull, and it is not afraid of water... In addition to being used as coin paper, it is also the main raw material for making nitroscopic cotton.
Moreover, Zhao Hao added an appropriate amount of lime powder to the cotton pulp used in the papermaking process. This lime powder is very magical. It can not only be used to boil cement, but also eliminate acidic substances in the paper and turn it into acid-free paper!
The reason why paper loses strength and fades is because acidic substances are at work. After using calcium carbonate to blend it, you can get the so-called permanent paper, making the paper more solid and flexible and not fade.
This kind of 'pure cotton acid-free paper' is fine when printing, and has excellent expressiveness on texture coatings. It can print more complex and fine patterns, which is beyond the reach of other papers at this time.
