Rome was not built in a day, nor can pure cotton and acid-free paper be made in a day.
In fact, as soon as Mr. Zhao got Xishan Island, he asked Zhang Zai and several paper craftsmen to secretly develop this pure cotton acid-free money printing paper in the military camp.
In order to allow Zhang Jian to concentrate on his research, Zhao Hao specially invited the scholar surnamed Jiao from Jinling to replace him as Li Zhi's assistant.
Zhang Zai is worthy of being the great inventor's uncle. It took him a hundred days to create a finished product that basically met the requirements.
"Of course, from Mr. Zhao's critical point of view, the quality of the banknote printing paper made in Xishan Island is quite inferior when compared with the fourth and fifth sets of RMB, as well as the third set of RMB.
But in the era of the Ming Dynasty, it was enough to crush the world, and no one could catch up in a hundred years.
Those masters of counterfeiting can¡¯t even print paper, so who gives them the courage to print counterfeit money?
Mr. Zhao, what kind of bicycle do you want?
??~~
"It's so hard for my brother to hide this from my little sister. He has such a treasure and doesn't show it to me." Jiang Xue faced a big problem and glanced at Zhao Hao with an infinitely beautiful look and said:
"As a result, my little sister didn't sleep well for several nights, and she even has dark circles under her eyes."
"My fault, my fault." Zhao Hao smiled and put his hands together to apologize. "I just got it, so I don't know if it will work or not."
¡°Try writing a few words first.¡± Secretary Ma picked up a piece of Huizhou ink depicting gold and began to grind it on an inkstone.
"Use this ink." Zhao Hao took out a small copper box from his sleeve as if he was offering a treasure again.
Ma Xianglan took the small copper box, carefully unscrewed the lid and took a look. She found that the ink inside was thick and shiny, which was completely different from ordinary ink.
"Do I need to add water?" Secretary Ma asked.
"Use it directly." Mr. Zhao shook his head.
Secretary Ma followed the instructions and dipped his brush in the copper box, and then wrote a line of poetry on the pure cotton acid-free paper.
¡®The plum blossoms are slanted by the moon, and there is a solitary figure, hating the ruthlessness of being let down all the time. ¡¯
"Don't think too much, don't think too much, this is Ma Zhiyuan's song "Rose dew, lotus leaf rain, chrysanthemum frost and cold fragrance in the courtyard." ' In the second half of the sentence, Sister Ma wrote it out with no other meaning at all.
¡°Well, it was just written by hand.
Then I heard Sister Ma cheer and say: "This character is written so brightly and the color is very symmetrical. It is most suitable for painting ink orchid."
"This is for printing money" Mr. Zhao reminded her seriously.
While trial-producing banknote printing paper, Zhao Hao also instructed Zhang Zai to configure a unique oil-based ink.
Traditional printing uses water-based ink. The words printed with water-based ink are afraid of water and are easy to smear. Oil-based ink is not only not afraid of water, but also allows printed matter to show strong, uniform colors and strong luster.
The production method is also very simple. Boil linseed oil, cool it, and use a small amount of distilled pine resin to obtain turpentine. Mix it with carbon black and leave it for a few months to make a suitable black ink.
??To prepare red ink, just replace the carbon black with cinnabar; for blue, replace it with azuriteall are mineral pigments that have been around for a long time.
It has been more than three months since the first batch of oil-based ink was trial-produced, and it is now available.
? Pure cotton acid-free paper with oil-based ink, how do you break it?
And this is the material used for the first set of banknotes. When Mr. Zhao¡¯s students figure out how to extract dye from coal tar in the future, they can print the second set of banknotes with bright colors and exquisite patterns.
By that time, the counterfeiters will know exactly what despair is.
Mr. Zhao laughed like a pig in his heart.
Jiang Xueying and Ma Xianglan could not help but secretly glance at each other.
They all saw surprise in each other¡¯s eyes¡ª¡ª
Brother, Master, how long ago did you start preparing to print banknotes?
It¡¯s so scary to think about it carefully, and the more I think about it, the more unfathomable it becomes
??~~
After completely no longer worrying about anti-counterfeiting issues, girls can finally focus on the layout design of banknotes.
Now even Qiaoqiao became interested. She lay down at the table and watched Sister Ma intently. Following Jiang Xueying's instructions, she drew on a piece of acid-free paper.
"Around the bank note, use two straight lines, one thick and one thin, to frame the edges. The four corners should be painted with patterns. The more complex the better."
"Write the four words Jiangnan Bank on the top, put a long box in the middle, and write a certain amount of official silver payable on demand" Jiang Xueying asked Ma Xianglan to fill in the necessary information, and then smiled at everyone: "Blank I can freely draw some patterns on the space, do you have any suggestions?"Mr. Zhao, who never forgets to promote science, immediately thought of printing some scientific patterns and slogans on the banknotes.
The first thing he thought of was hot air balloons, but after thinking about it, he decided to forget it.
How about printing the three laws of mechanics? No one seems to understand
¡°Hey, it¡¯s better to be more down-to-earth, promote the ten scientific numbers, and then print the simple addition and subtraction formulas, as well as the multiplication formulas, which will be more useful.
Thinking of this, Mr. Zhao couldn't help but feel bored. A good banknote has become a preschool knowledge card. No matter how you design it, it will never look like Boeygue
"Why don't we paint the young master on it!" At this moment, Qiao Qiaoshi suddenly suggested something shocking.
¡°What a great idea!¡± Jiang Xueying and Ma Xianglan immediately agreed in unison.
Ma Xianglan immediately outlined the frame with a thin lead chisel.
After a while, Mr. Zhao, holding a telescope and smiling, appeared on the bank note.
"Well, it smells bad" Zhao Hao nodded and said: "But the expression should be more serious, the eyes should be wiser, and it is best to have the feeling of knowing everything."
"Yeah, I'll change it right now." Secretary Ma naturally followed suit.
"Shit!" Mr. Zhao came back to his senses and cursed with a smile: "Put me on it, will I have to go out again?"
"Oh" Secretary Ma blinked, thinking that the young master is so confused.
"This version of the banknote does not require portraits." Mr. Zhao still did not have the guts to be the person on the banknote, so he could only think to himself:
¡®Just wait for the next edition. When it can be printed in full color, you must have your face printed on it. ¡¯

Jiangnan Bank is preparing to launch banknotes in five denominations, each with different sizes.
Of course, the larger the denomination, the larger the size.
The four of them had a heated discussion until midnight, and finally settled on five general styles of banknotes.
The half-liang bank note has the Wusong River Embankment in Kunshan as the main image, and the multiplication table on the back.
The banknotes with one or two denominations have a world map as the main image, and on the back is a subtraction table within twenty.
The 20-tael banknote has Jiangnan Hospital as the main image, and on the back is an addition table within 20.
The 50-tael denomination silver note has the Yufeng Academy, which has just been built and is still under renovation, as the main image. On the back is the division table by ninety-nine.
The twelve denomination silver notes feature Zheng He¡¯s super fleet as the main image.
On the back is another world map, but unlike the front image of the one-tael silver note, this map is larger and more detailed, clearly marking the results of Spain and Portugal's carving up the world.
This is a very disturbing pattern.
Because one of the two countries goes around the Cape of Good Hope, from Africa through India to Malacca.
? One goes from Europe to Mexico, and then across the Pacific to Luzon.
