Cold Fragrance Garden, in the Water Cloud Pavilion.

Jiang Xueying and Ma Xianglan were sitting side by side at the desk, discussing something intently.

Qiaoqiao sat bored on the side, and when she saw Zhao Hao coming in, she couldn't help but frown.

She was about to speak, but Zhao Hao put her finger to her lips and signaled Qiaoqiao not to disturb the two of them.

He crept over and stood behind the two of them, listening to their serious discussions.

It smells good.

Well, Zhao Gongzi refers to the seven or eight tickets with different styles on the table, as well as the extinct Daming treasure banknotes on the market.

Well, the smell of money, nothing else.

"In fact, over the years of running the bank, Wu Ji has accumulated a set of anti-counterfeiting methods for membership tickets, such as watermarks, miniature carvings, etc."

Jiang Xueying used her slender fingers to pick up a ticket for Wu Ji, and Huang Ying explained as crisply as a valley:

"You see a circle in the middle of the Wu Kee meeting ticket, and there is a blank space in the circle when you look at it, but when you lift it up to the light, you can see five connected peaks, which is our Wu Kee's 'watermark secret mark'."

"How is this printed?" Ma Xianglan asked curiously.

"I heard that it was formed by changing the thickness of the pulp through the change of the wire mesh during papermaking." Jiang Xueying explained: "And there are also secret marks on the font and pattern on the watermark, and Qian Zhuang can know the authenticity at a glance." ”

As she spoke, she pointed to the red seal in the lower right corner of the ticket. "As for the miniature carving chapter, my sister is proficient in calligraphy and painting, so I don't need to explain it."

"Hmm." Ma Xianglan nodded, the content of the miniature carving chapter is a few hundred words of poetry, and the carving is very fine, which cannot be carved by ordinary technology.

Because the content is too complex and detailed, even the original carver can no longer carve out the same miniature carving as before.

Moreover, Qian Zhuang will deliberately leave some impurposible flaws when carving, which is even more difficult to forge.

"But it's too hard for ordinary people to tell the difference. So we still have to work on something more intuitive. ”

Jiang Xue greeted and said: "It's like our Wu Ji, we use special hemp paper, and the recipe is the top secret of Qianzhuang, and only three or five people know it." It's the same with inks. ”

Then she picked up the Wanyuan ticket and said: "This is the best ticket on the market today, using a special formula of Sichuan paper, and there is a red grid and green line printed on it, which is not only beautiful, but more importantly, it is difficult to forge." ”

"Hmm." Secretary Ma nodded, his fingers supported the glasses on the bridge of his nose, and his voice was soft and glutinous:

"Two-color overprinting is not difficult, and our own printing workshop can do it."

"We can't just meet the two-color overprint, but also the three-color overprint." Zhao Hao interjected with a smile.

"Brother is back?" If you were someone else, you would definitely be taken aback by him, but Jiang Xueying and Ma Xianglan, who were not shocked, were very calm.

"Son, let's change people quickly, Sister Xue Ying has to make the best quality silver ticket." Ma Xianglan got up to make way for Zhao Hao, and couldn't help but smile bitterly: "How do I understand this?" You settle down, and I will do what you say. ”

Sister Ma will not only hide clumsy, but also show weakness, and her rank is much higher than Jiang Xueying. Even President Jiang, who is as wise as a torch, can't see that she is a foreign Erwuzi, and she still regards Sister Ma as a good girlfriend of the Ming Dynasty.

Zhao Hao sat on Ma Xianglan's chair and said with a smile: "Xue Ying is right, our silver ticket is bearer, the ticket is not recognized, and the silver will be paid when you see the ticket." The requirements for anti-counterfeiting are much higher than those of general votes. ”

"Yes, the meeting ticket recognizes the vote and the person, and there are reserved seals and secret seals, which are enough to make people unable to forge them." Jiang Xueying nodded and said distressedly:

"But if we want to circulate our silver bills in the private sector without going through the bank, most of the means cannot be used, so we can only work the printing of silver bills."

The seal and signature on the ticket must be verified by the money bank with the reserved information in order to identify the authenticity. How can ordinary people outside the money bank do it?

In order for the silver ticket to play the role that Zhao Hao envisioned, it must overcome this problem. So that ordinary people can also distinguish the authenticity of the silver ticket.

There are not too many counterfeiters in Jiangnan, and even "Qingming Riverside Picture" can be made as a fake and real fake, not to mention a small silver ticket?

Don't let the counterfeiters deter and dispel the idea of counterfeiting. It is believed that there will soon be countless counterfeit silver tickets on the market.

Ordinary people can't receive every silver ticket, so they go to the bank to check the authenticity. When I turned around and found that I had received a fake silver ticket that couldn't be exchanged for silver, I must have blown up my lungs.

There are many such things, who would dare to collect cash tickets and use silver tickets in daily trading?

In that case, the bank bill of Jiangnan Bank will lose its monetary attribute and return to the level of 'withdrawal order', what is the difference between it and the meeting ticket?

If you can't satisfy your dream of printing money, what bank will Zhao Gongzi open?

~~

"Sister Sensei is worried, let's prevent counterfeiting scientifically, and no one can copy it." Zhao Gongzi was in his chest, and as he spoke, he took out a few pieces of white paper from his arms and put them on the table.

He has always been unhindered, and he even has to hold handkerchiefs and sunglasses by others, but he sticks these papers on his body and collects them, which shows what a treasure.

The second daughter hurriedly looked at the paper carefully, and even Qiaoqiao picked up one of them, and couldn't help exclaiming: "It feels so good, it's quite scratchy." ”

Jiang Xueying also nodded and said, "It's really tough." ”

Saying that, she also folded, but there was no crease.

"Tear it up and see." Zhao Hao smiled again.

Ma Xianglan twisted the ends of the paper to tear it, but it took a lot of effort to tear it out of shape.

"I can't tear it, how do you make this paper?"

Zhao Gongzi smiled slyly and said, "This is a corporate secret. ”

He asked Qiaoqiao to bring the basin over and soak the paper in the water.

As a result, it was soaked for a long time, and the paper was not deformed or damaged.

In the end, Zhao Gongzi took out the lamp and burned a piece of paper, but it only smoked and burned, but there was no fire......

"I believe that in a few decades, no one should be able to imitate this kind of paper." Zhao Gongzi smiled and asked, "If you use a silver ticket, it should be more suitable." ”

Of course it's appropriate. Because this is the banknote printing paper of the renminbi four hundred years later.

Different from the bamboo wood pulp used to make paper at this time, wood pulp only accounts for half of the raw materials of banknote printing paper, and the remaining ninety percent is cotton linters.

Cotton linter is also called 'cottonseed lint', which is the residual fiber on the wool cotton seed after cotton ginning.

Because the nutrients are easier to transport to the linters, the content of cotton linter cellulose far exceeds that of normal lint, so it is used to make paper with full toughness, difficult to tear and not afraid of water...... In addition to being used as coinage paper, it is also the main raw material for nitrocellulose.

Moreover, Zhao Hao also added an appropriate amount of lime powder to the cotton pulp of papermaking. This lime powder is amazing, not only can it be used to burn cement, but it can also eliminate the acidic substances in the paper, making it acid-free paper!

The reason why the paper loses strength and fades is because of the acidic substances, and after neutralizing it with calcium carbonate, the so-called permanent paper can be obtained, making the paper more solid and flexible without fading.

This 'cotton acid-free paper' has a delicate transition layer during printing, and the expressiveness of the texture coating is excellent, and it can print more complex and delicate patterns, which is beyond the reach of other papers at this time.

P.S. I'm going to have to wait for the next chapter.
