Chapter 770 Anti-counterfeiting

Previous page        Return to Catalog        Next page

    Lengxiang Garden, in Shuiyun Pavilion.

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

    Qiaoqiao was sitting aside bored, and when she saw Zhao Hao coming in, she couldn't help but be happy.

    Just as she was about to speak, Zhao Hao put his finger to his lips, signaling Qiaoqiao not to disturb the two of them.

    He tiptoed over and stood behind the two of them, listening to their serious discussion.

    It smells pretty good.

    ¡°Well, Mr. Zhao is referring to the seven or eight conference tickets of different styles on the table, as well as the Ming Dynasty treasure banknotes that have disappeared from the market.

    Well, the smell of money is nothing else.

    "Actually, over the years of running a bank, Wu Ji has accumulated a set of methods to prevent counterfeiting of banknotes, such as watermarks and micro-engraved seals."

    Jiang Xueying used her slender fingers to twist up a piece of Wu Ji's meeting ticket, and explained as crisply as an oriole leaving the valley:

    ¡°Look at the circle in the middle of the Wuji ticket. When you look at it flatly, the circle is completely blank. But when you hold it up to the light, you can see five connected peaks. This is our Wuji¡¯s ¡®watermark¡¯.¡±

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

    "I heard that it is formed by changing the thickness of the pulp through changes in the silk screen during papermaking." Jiang Xueying explained: "And there are also hidden marks on the fonts and patterns on the watermark. The banker can tell 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 micro-engraved 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 is a few hundred words of poetry. The carving is very detailed and cannot be carved with ordinary technology.

    Because the content is too complex and detailed, even the original engraver cannot carve the same micro-engraved seal as before.

    ¡° Moreover, the banker will deliberately leave some hard-to-detect flaws during engraving, making it even more difficult to forge.

    "But for ordinary people, it is too difficult to distinguish. So we still have to work hard in a more intuitive way."

    Jiang Xue greeted him and said, "For example, we, Wu Ji, use special hemp paper. The formula is a top secret of the bank and only three or five people know it. The same goes for the ink."

    Then she picked up Wanyuan's ticket and said: "This is the best ticket on the market today. It is made of specially formulated Sichuan paper and has red grids and green lines printed on it. Not only does it look good, but more importantly, it is  It¡¯s hard to fake.¡±

    "Yeah." Secretary Ma nodded, held up the increasingly smaller glasses on the bridge of his nose with his fingers, and said in a soft and waxy voice:

    ¡°Double-color overprinting is not difficult, we can do it in our own printing workshop.¡±

    ¡°We can¡¯t just be satisfied with two-color overprinting, we also have to do three-color overprinting.¡± Zhao Hao interjected with a smile.

    "Brother is back?" Anyone else would have been shocked by him, but Jiang Xueying and Ma Xianglan, who were calm at all times, were very calm.

    "Master, please change someone quickly. Sister Xueying must make the best quality banknotes." Ma Xianglan stood up to make room for Zhao Hao, and couldn't help but smile bitterly: "How do I understand this? You decide, I will draw it according to your instructions.  That¡¯s it.¡±

    Sister Ma not only hides her clumsiness, but also shows weakness, and her rank is much higher than Jiang Xueying's.  Even the sharp-sighted President Jiang couldn't see that she was just a young man with foreign knowledge, and he regarded Sister Ma as a good friend of Ming Dynasty.

    Zhao Hao sat on Ma Xianglan's chair and said with a smile: "Xue Ying is right. Our banknotes are anonymous, the person who recognizes the ticket is not recognized, and the banknote is paid upon seeing it. The anti-counterfeiting requirements are much higher than ordinary banknotes.  ¡±

    "Yes, the meeting vote can be recognized by both the vote and the person. The reserved seal and signature are enough to make it impossible to forge." Jiang Xueying nodded and said distressedly:

    "But if our banknotes want to be circulated among the people without going through banks, most of the methods are useless. We can only work hard on the printing of banknotes."

    The signatures and signatures on the tickets must be verified by the banker with the reserved information to determine the authenticity.  How can ordinary people outside of banks do this?

    ¡° If the banknote is to play the role Zhao Hao expected, it must overcome this problem.  Let ordinary people also be able to tell the authenticity of banknotes.

    There don¡¯t need to be too many forgery masters in Jiangnan. Even "Along the River During the Qingming Festival" can be faked to look like the real thing, let alone a small banknote?

    Don¡¯t let the masters of counterfeiting be deterred and give up the idea of ??counterfeiting.  I believe that countless fake banknotes will soon enter the market.

    People cannot receive every bank check, so they go to the bank to check whether it is genuine or not.  When I turned around and found out that I had received a fake banknote that could not be redeemed, I would have been furious.

    "When there are so many things like this, who dares to collect cashier's checks or use banknotes in daily transactions?"

    ? ?In this way, the bank notes of Jiangnan Bank have lost their currency attributes and have returned to the level of "withdrawal orders". What is the difference between them and meeting notes?

    If Mr. Zhao cannot satisfy his dream of printing money, what kind of bank can Mr. Zhao open?

    ??~~

    "Don't worry, sister, we are scientifically guarding against counterfeiting, and I'm sure no one can imitate it." Mr. Zhao was confident, 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 had nothing to worry about. Even his handkerchiefs and sunglasses have to be carried by others, but he keeps these papers close to his body, which shows how precious they are.

    The two girls quickly looked at the paper carefully, and even Qiaoqiao joined in the fun and picked up one, exclaiming: "It feels really good, it's very scratchy."

    Jiang Xueying also nodded and said: "It is indeed tough."

    As she said this, she folded it, but there was no crease.

    "Tear it apart again." Zhao Hao laughed again.

    Ma Xianglan twisted the two 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 open. How is this paper made?"

    Mr. Zhao 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, after being soaked for a long time, the paper was not deformed or damaged.

    Finally, Mr. Zhao took out the lamp again and burned a piece of paper. The result was that it only smoked and burned, but no fire appeared

    "I believe that within a few decades, no one should be able to imitate this kind of paper." Mr. Zhao asked with a smile: "It would be perfect to use it to print banknotes."

    Of course it¡¯s appropriate.  Because this will be the paper on which RMB banknotes will be printed four hundred years from now.

    Unlike the bamboo pulp used to make paper at this time, wood pulp only accounted for half of the raw materials for banknote printing paper, and the remaining 95% was cotton linters.

    Cotton linters are also called ¡®cotton linters¡¯, which are the remaining fibers on the cotton seeds after ginning.

    Because nutrients are more easily transported into the linters, the cellulose content of cotton linters is much higher than that of normal lint. Therefore, paper made from cotton linters is very tough, difficult to tear, and is not afraid of water In addition to being used as currency paper  , or the main raw material for making nitrocellulose.

    And Zhao Hao also added an appropriate amount of lime powder to the cotton pulp used in papermaking.  This lime powder is very magical. Not only can it be used to burn cement, it can also eliminate acidic substances in paper, turning it into acid-free paper!

    The reason why paper loses strength and fades is because of acidic substances. After neutralizing it with calcium carbonate, you can get so-called permanent paper, which makes the paper stronger, more flexible and does not fade.

    This kind of 'pure cotton acid-free paper' has delicate transition levels during printing, and has excellent expressiveness for texture coatings. It can print more complex and delicate patterns, which is beyond the reach of other papers at this time.

    ps. I have to wait for the next chapter.  (Remember the website address: www.hlnovel.com
