I was chased by my sickly junior brother who had two lives

In Qing, Chen Jia and Chen Jue's banknote business is booming, but they are faced with a severe challenge from fake banknotes. After discovering the fake banknotes, Chen Jia quickly takes action and is determined to upgrade the anti-counterfeiting technology of banknotes in many aspects to ensure the safety and credibility of banknotes.

That day, Chen Jia was sitting in her study, with a pile of paper samples and banknote design sketches in front of her. Chen Jue walked in, looked at her focused look, and asked softly, "Madam, do you have any new ideas for improving the anti-counterfeiting of banknotes?"

Chen Jia raised her head, her eyes revealing determination and wisdom, and said, "My husband, I have thought about it carefully. We have to start with the paper, printing and other aspects of the banknote. For the paper, I plan to change the production method and add wool to make the smell of the banknote different when burned, so as to use it as a new anti-counterfeiting mark."

Chen Jue frowned slightly, thought for a moment and said, "Madam, this is a novel idea. But will adding wool affect the texture and toughness of the paper? Moreover, how to control the proportion of wool to ensure that the taste of each banknote is unique and easy to identify?"

Chen Jia smiled and explained, "Sir, I have discussed this with the paper craftsmen. Adding an appropriate amount of specially treated wool will not only not affect the texture of the paper, but will enhance its toughness. As for the wool ratio, we can set strict standards to ensure that each batch of paper is consistent. As for the taste, the wool is specially smoked to produce a unique burnt aroma, which is completely different from the smell of burning ordinary paper. With a little training, the guys in the bank can easily distinguish it."

Chen Jue nodded in agreement: "My lady, you have thought so carefully, I believe this method is feasible. In addition to paper, are there any other improvement measures?"

Chen Jia picked up a silver bill sketch, pointed at the design on it and said, "Sir, I also plan to add a secondary link to the silver bill. The primary link is used for normal transactions, and the secondary link is kept by the bank. There will be some encrypted information corresponding to the primary link on the secondary link, such as special numbers, hidden patterns, etc. When the authenticity of the silver bill needs to be verified, the primary and secondary links can be easily identified by comparing them."

Chen Jue looked at the sketch and praised, "This is a good idea. With an extra layer of protection, it will be much more difficult to forge. What do you think about printing technology, madam?"

Chen Jia said enthusiastically: "In terms of printing technology, I want to use a technology that combines multi-plate overprinting with microtext. First, use different printing plates to print different colors and patterns of the banknotes to ensure accurate overprinting, bright colors and rich layers of patterns. At the same time, in the blank spaces of the banknotes, use very fine lines to print microtext. The text content can be important information such as the name of the bank and the issue date of the banknote. These microtexts are difficult to see with the naked eye and require the help of a special magnifying glass to identify."

After hearing this, Chen Jue couldn't help but admire: "Madam, your series of anti-counterfeiting designs are so ingenious. However, these new production and printing technologies must have very high requirements for craftsmen, and they may be difficult to implement."

Chen Jia said confidently: "My husband, I have gathered the best paper craftsmen and printing masters in the country and discussed the feasibility of these technologies with them in detail. Although they also feel that it is challenging, they all expressed their willingness to try. We can also set up an incentive mechanism to encourage craftsmen to unleash their creativity and overcome technical difficulties."

As they were talking, the housekeeper came in to announce that the paper craftsmen and printing masters had arrived. Chen Jia and Chen Jue immediately went to the workshop to meet the craftsmen.

The paper craftsman said respectfully, "Madam, we have a preliminary plan for adding wool to paper. We plan to degrease and soften the wool first, then mix it with the pulp in a precise proportion. During the papermaking process, we will use a special stirring and pressing process to ensure that the wool is evenly distributed in the paper."

Chen Jia nodded and said, "Master, thank you for your hard work. The key is to ensure the accuracy of the wool ratio and the stability of the paper quality. If you have any difficulties during the experiment, please feel free to raise them. We will fully support you."

The printing master continued, "Madam, we are also researching multi-plate overprinting and microtext printing technology. Multi-plate overprinting requires some modifications to the printing equipment to improve the accuracy of overprinting. Microtext printing requires special printing plates and sophisticated operating skills. We will conduct experiments as soon as possible and strive to produce satisfactory results as soon as possible."

Chen Jia encouraged: "Master, your skills are superb, and I have confidence in you. These two technologies are crucial to anti-counterfeiting of banknotes. I hope you can overcome difficulties and succeed soon."

In the following days, Chen Jia closely followed the research and development of paper and printing technology, and she often came to the workshop to discuss improvement plans with the craftsmen.

One day, the paper craftsman came to Chen Jia excitedly and said, "Madam, after many experiments, we finally found the most suitable wool ratio and processing method. You see, this newly made paper has a tough texture, and it has a unique smell after burning, which is easy to identify."

Chen Jia took the paper, observed it carefully, then lit a small corner, smelled the burning smell, and said with satisfaction: "Master, you did a great job! This smell is really unique, and the anti-counterfeiting effect is significant. Next, we must improve the production process as soon as possible to ensure that the quality of each silver note paper is consistent."

At the same time, the printing master also brought good news: "Madam, the multi-plate overprinting and micro-text printing technology has been successfully tested. You see, the pattern on this banknote is brightly colored, the overprinting is accurate, and the micro-text is clearly legible."

Chen Jia looked at the printed banknote sample and said happily: "Master, you really lived up to my expectations. However, in order to prevent the leakage of technology, these printing equipment and printing plates must be properly kept, and the craftsmen involved in the production must sign a confidentiality agreement."

Thanks to Chen Jia's efforts, the new silver note production technology gradually matured. In order to make the staff of money houses and banks familiar with the anti-counterfeiting features of the new silver notes, Chen Jia personally organized training.

"Look everyone, this is a new silver note. First, when you get the silver note, smell the paper first. If there is a special burnt smell, it means that the paper contains specially treated wool. This is the first step in anti-counterfeiting. Then, use this special magnifying glass to check the microtext in the blank space of the silver note to verify whether the text information is correct. Finally, compare the silver note with the duplicate copy kept by the bank to check whether the number and dark pattern are consistent." Chen Jia explained in detail.

The staff studied seriously and asked questions constantly, and Chen Jia answered them patiently.

After the new silver bills were launched, they were quickly recognized in the market. Merchants were more confident about the safety of silver bills, and the credibility of silver bills was further improved. Chen Jia's series of anti-counterfeiting measures not only effectively curbed the proliferation of fake silver bills, but also made important contributions to the stability of Qing's financial market.

Chen Jue looked at the busy and confident Chen Jia, and said with emotion: "My wife, thanks to your wisdom and hard work, our banknote business can be saved from danger and move to a higher level."

Chen Jia smiled and said, "Husband, this is our common cause. Only by continuous innovation and improvement can we remain invincible in the complex business environment."

Under the careful management of Chen Jia and Chen Jue, their silver bill business continued to flourish and became the mainstay of Qing's commercial and financial sector.
