Chapter Seventy-Nine: Color Printing Adhesive Fibers

When he sent a telegram to Emperor Chongzhen to report the situation of the war in Annan, Zhang Zhimu asked Li Zhi to come over and translate it into a code. Originally, the battle situation did not need a password, but Zhang Zhimu also told the emperor how to deal with Li Zicheng's suggestion. I was afraid that others would know, so I used a password. Zhang Zhimu suggested that when Li Zicheng completely resolved the matter of Annan, he asked the emperor to send a messenger to Annan to officially canonize Li Zicheng as the governor of Annan.

Of course, Emperor Chongzhen will do favors, which Emperor Chongzhen and Zhang Zhimu have a tacit understanding.

After drafting the telegram, Zhang Zhimu said to Li Zhi: "Li Zhi! There is no suspense about the affairs in our Ming Dynasty. I have a suggestion that you should set up two larger intelligence centers in Quanzhou and Jiayuguan, which will always be responsible for intelligence outside the country. Your headquarters will also set up an overseas intelligence center to study the intelligence of various countries. In the future, we will rely heavily on overseas intelligence, so you need to prepare in advance. ”

"Okay, Mr. Zhang." Li Zhi said, "We have a lot of intelligence personnel in Quanzhou. This time, after we took Fujian, we sent some people over. There are quite a few people who are well versed in the affairs of various countries. We can put them to good use. ”

"By the way, we are going to set up a language college in Quanzhou, and we will also set up a navigation college. Your people can be placed directly in these two units. Zhang Zhimu said, "A lot of information is obtained from public information. You can set up an academic institution such as a Western Research Center in the Language Institute, or you can hire foreigners, and you can get a lot of public information from these institutions. ”

Li Zhi nodded yes, he simply admired this very far-sighted boss, because Zhang Zhimu always thought of everything in front, especially the affairs of the intelligence department. Now the leaders at all levels of the kiln gang are affected by Zhang Zhimu's point, and the leaders think that things are a little ahead of their time.

Influence is often a strange thing, often unclear, but it is often more useful than preaching.

Although Li Zhi is also trying to think about some things in advance, he often has to follow Zhang Zhimu's request for half a beat.

During this time, Zhang Zhimu was very leisurely, so he accompanied Xiao Hongyu to play with the children at home.

Zhang Zhimu found that Xiao Hongyu at home couldn't be idle, as long as he was at home with the children, the phone in Xiao Hongyu's hand could hardly be put down. She either directs the movie, or arranges the affairs of the art academy, and even the Spring Festival Gala, Class Master Liu has to come to the house to discuss with Xiao Hongyu. Zhang Zhimu felt that this little red jade's desire for power was too great, and asked her: "You are at home, can't you put everything outside alone?" ”

"Oops! I don't worry about them," Ruby explained, "or they'll make a mess and I'll have to clean it up again when I get to work." You don't care about everything! ”

"I think you have too much power, in fact, if you let everyone do it, it doesn't necessarily mean that it's worse than this remote control." Zhang Zhimu said, "Your main task now is to take our son well. ”

"Good! Listen to you, otherwise you still think I'm Wu Zetian! Xiao Hongyu knows how to advance and retreat very well, but she can't help but have some resentment in her mouth.

The two of them teased the child for a while, and Xiao Hongyu said: "Now this phone can be dialed, it's really convenient, and you don't have to wait for the switchboard to ask for a number." You don't know, except for our company's number, it used to be very difficult to get through the outside number. Now it's okay, basically pick it up and dial it, as long as the other party is not busy, it will be through immediately. ”

"That's right! You don't know how long Yang Chang and the others have been studying this thing. Now they're working on long-distance dialing. In the future, if you want to make a call to your hometown, you should also add an area code in front of it, and then dial the other party's number. Zhang Zhimu described the prospect of long-distance direct dialing to Xiao Hongyu.

"Then hurry up!" "The sisters I grew up with when I was a kid don't know what happened? Then he sighed and said, "Alas! How can they have my blessing, even if they get through, they can't have a phone at home. ”

"So! We still have to fight so that everyone in the world has electric lights and telephones. Zhang Zhimu said.

"I've heard that Datong, Xi'an, Taiyuan, and Kaifeng have changed to automatic dialing. Wuhan is directly on the automatic dial-up. Is it possible to dial directly over long distances when you go to the place of automatic dialing in the future? "Little Hongyu is very smart, and immediately thought about long-distance dialing.

"Yes! In the future, the whole country will have to make long-distance direct dials. Zhang Zhimu said.

"I said, can you give me a better number for this phone?" Little Ruby has an idea.

"I can't help it, let Mr. Lu auction the good numbers."

In fact, the number auction was a wake-up call from Zhang Zhimu to Lu Chengxiang. Of course, Lu Chengxiang is thorough. Before the number auction, Editor-in-Chief Fan also cooperated with the publicity, saying how important a simple and easy-to-remember Geely number is to business and home interactions, and so on.

When many people asked people to ask for good numbers, Lu Chengxiang asked people to publish them in the newspaper, because they all want an auspicious number now, for the sake of fairness, all numbers are auctioned publicly, and the highest price wins. At the same time, some special numbers were announced, which were not as good as 19999, 18888, 16666 and other auspicious numbers. Now, things are lively. After everyone discussed it repeatedly, the fermentation was almost over, and Lu Chengxiang announced the date of the public number auction.

When it comes to the auction, Lu Chengxiang is really familiar with it. As a result, what I didn't expect was that several large business groups competed for the first few auspicious numbers at the beginning. In the end, it was not until a number of 20,000 taels of silver was won that it was sold. The other Geely also have more than 10,000 taels. Those small households stared at each other, they knew that such a good name was not something they could get into. Those who got the good numbers were beaming. Until I got out of the auction hall, I regretted not competing. I was wondering if this good name was ours if I added a little more silver at that time. Now that you have the number in hand, you can get a long price right away.

All the merchants who photographed the Geely number, without exception, reprinted their business cards with the best cardboard, and that pride was written on the business cards.

Xiao Hongyu asked Zhang Zhimu to get a good number, but Zhang Zhimu was powerless.

At this time, Yang Yulin called the phone, obviously a little sour, "In broad daylight, you don't come to class, soak there endlessly?" ”

Xiao Hongyu heard the roar on the phone, and covered her mouth and didn't dare to laugh. Zhang Zhimu also endured it and said, "Miss, if you have something to do, don't be so angry." I'm okay today, I came to see my son, and I don't have time in the evening. ”

Hearing Zhang Zhimu say this, Yang Yulin also knew that she was a little excessive, and said, "Who cares about your." Yang Chang called a few times, you call him back. And Master Qingfengzi also called, you can give one back! After speaking, without waiting for Zhang Zhimu to speak, Yang Yulin's phone was released.

Looking at Zhang Zhimu's expression, Xiao Hongyule rolled all over the bed. Zhang Zhimu went directly, hugged Xiao Hongyu and kissed for a while, and was busy again. When the two of them were breathless, Xiao Hongyu smiled and said, "Hehe! Sister Yulin has two children, and the sour energy is still so big. I guess Yulin won't be able to let you go tonight. Can you still do it? ”

"Humph! Look down on me," Zhang Zhimu pinched Xiao Hongyu's face and said, "I don't have the ability to fight group pets at night, and it's okay to deal with a few people at home." ”

"Huh!" Little Ruby is a laughing flower branch trembling.

Zhang Zhimu thinks it's really good to cross over, and you can get a few wives. If you didn't have this blessing in your previous life, except for being a big official and making a fortune.

After a break, Zhang Zhimu picked up the phone and wanted to call Yang Chang, but he couldn't think of Yang Chang's phone at once, so he had to call the switchboard and ask. This made Zhang Zhimu suddenly remember, and there were also business opportunities in the phone yellow book, so he called Lu Chengxiang first, "Mr. Lu, I have an idea." Is it possible to print the phone numbers of various businesses and people who are willing to publish their home phone numbers in a booklet? Otherwise, it is very troublesome to find a phone number and ask the switchboard once. We can advertise it in this brochure. Some businesses want everyone to know their number, so they can register their number larger. If you want to introduce their products, you can also post the entire post. Do you think it's a business opportunity? ”

"That's right! It's convenient for everyone, and you can earn money. Lu Chengxiang immediately saw that he was making money. Although this bit of silver has long been out of Lu Chengxiang's eyes, Lu Chengxiang, who is sensitive to earning silver, will not let go of any business opportunities.

After talking to Yang Chang, Yang Chang told Zhang Zhimu the good news that the echo detector had been successful, and they had done a good job in the experiment.

Zhang Zhimu said to Yang Chang: "You wait for my news, I will contact Shi Tao immediately and ask them to send some people to do experiments with you." You can now experiment in the pool of the Diving Equipment Institute, which has several steps at different depths. ”

Zhang Zhimu knew that this was sonar. But now you can't use English transliteration here, so it's good to call it an echo detector.

After Shi Tao heard Zhang Zhimu introduce this kind of echo detector, he immediately said: "Mr. Zhang, I will bring a few over immediately." It's too important to us on board. I'll go right over. ”

Although Shi Tao didn't say much, Zhang Zhimu could tell from Shi Tao's tone that he was already extremely excited. Zhang Zhimu can understand this very well, because with this echo detector, for the sailing ship, it is like installing a pair of eyes in the water under the ship. Sailing is no longer blind.

After dialing the phone to Master Qingfengzi, Qingfengzi said on the phone: "Mr. Zhang, come over when you have time!" ”

I haven't seen Qingfengzi for a long time, Zhang Zhimu doesn't know what Qingfengzi has researched again, and I really want to talk to him. Zhang Zhimu knew that Qingfengzi was not a person who had nothing to chat with him.

Putting down the phone, Zhang Zhimu hugged Xiao Hongyu and kissed it, saying, "This gentle township can't stay for too long." I'm going to Master Qingfengzi. ”

"Huh! You wash your face before you go, and the lipstick should be washed clean. Xiao Hongyu reminded Zhang Zhimu that she rubbed lipstick on her face.

After washing his face, Zhang Zhimu drove to Yaogang College by himself. When he came to Qingfengzi's laboratory, Qingfengzi said to Zhang Zhimu: "Mr. Zhang, how about you come and see our color printing?" ”

Zhang Zhimu went over, followed the direction pointed by Qingfengzi, saw a few pieces of paper printed with color images hanging on the table, hurriedly went over and picked up a piece of paper that still smelled of ink, and saw that it was really a color image, and said with great joy: "Master Qingfengzi, you have really successfully developed color printing?" ”

"Those who are engaged in printing in the printing factory used to use several color templates for printing, including our kiln coins. However, if you want to print a clearer color image, you can't do it. Ever since you told them about the principle of color, the principle of additive color, the principle of subtractive color, the three primary colors, and so on, they began to study color printing. But they didn't have the right ink, so Editor-in-Chief Fan came to me. I don't think it's easy, with their current knowledge, I'm afraid they won't be able to make this thing. I'll take it and do it. Last time I asked you some questions, and that's what it is. ”

Zhang Zhimu then remembered that Qingfengzi had discussed color printing and plate making with him several times. Since Zhang Zhimu himself is also half-understood, he said everything he could say, so he didn't care anymore. I didn't expect Qingfengzi to really come out. Although their current printing level cannot be compared with the effect of those color wall calendars in their previous lives, it is not easy, at least it is much better than the color printing effect on the original newspapers.

Qingfengzi introduced their method of plate making, which is to take three photographs of the image, each time filtering different light with a color filter of the corresponding color. Without splitting colors, the desired result is three gray images representing the red, green, and blue components of the original. The next step is to convert each color separation. When generating a negative image of the red component, the resulting image represents the blue component of the image. Similarly, a yin picture of the green and blue components is generated in order to generate magenta and yellow separators accordingly. Cyan, magenta, and yellow are subtractive primary colors, and when combined in printing, these three colors can make a reasonable reproduction of the original, but this is not the case in practice. Due to the limitations of ink pigments, the darker colors produced are dirty and stainy. In order to solve this problem, a black version was also made to improve the color of the dark parts and improve the contrast of the image.

When making plates, the technology used to make kiln coins was used, and metal zinc plates were used.

First, the surface of the metal zinc plate is ground to establish a sand mesh, and then the corrosion is carried out to eliminate the residual mud and oxide layer after the grinding plate. At the same time, the acid corrosion liquid can slightly corrode the layout of the sand mesh, forming a very fine unevenness and increasing the adsorption capacity. Then, a protein-containing photosensitive solution is applied. Then the printing plate and the negative film are closely exposed, because the transparent part of the negative is the graphic part, so the photosensitive layer of the graphic part on the protein plate is irradiated by the light and undergoes a photochemical reaction. After the protein plate is exposed, it is rubbed with a layer of uniform and highly greasy developing ink, so that the light-sensitive hardened adhesive layer can absorb the developing ink, which is lipophilic. When developing, rinse with water and scrub with cotton to leave a hardened rubber layer, which is the printed part. Finally, there is corrosion and gluing. Corrosion is the complete removal of the unexposed adhesive layer to prevent dirtiness during printing. Gluing is to prevent oxidation of the layout and establish a stable blank part.

Zhang Zhimu didn't understand these methods, he had heard of some of them, that is, he simply gave them a brief explanation, and the specific ones were the results of Qingfengzi's repeated experiments.

Zhang Zhimu said to Qingfengzi: "The Spring Festival is coming soon, and we should print some wall calendars on coated paper." It's just a kind of yellow calendar, an image, just use the big heads of the actors we play in the movie, and this kind of thing will definitely be welcomed. The calendar can also be printed with some content such as our product introduction. Specifically, I'm discussing it with Editor-in-Chief Fan. If there is a colorful wall calendar for the Spring Festival this year, then it will be even more lively. If you don't get it, everyone will come over to grab the calendar. ”

Qingfengzi scratched his head and said: "We can only print a few thousand copies of this kind of printing plate, and then the quality is not very good. ”

"Then print a few thousand copies, and if you print more, it's not worth the silver." Zhang Zhimu said, "If we print more in the future, we can make several more boards at the same time!" ”

"There is still a lot of room for improvement in this printing method, and the ink also needs to be improved." Qingfengzi said, "However, it can barely be used." Much stronger than those black and white. ”

"Yes, with us, we can improve it slowly." Zhang Zhimu said, "However, I am more concerned, when will your color photos come out?" ”

"It's harder," said Qingfuzi, "but now we've found red and green materials that are sensitive to light, but blue isn't ideal." Such a material should be transparent, and it should be sensitive to light, so it is difficult to find, so let's study it in a different way. ”

"It's really difficult," Mr. Zhang said, "but if there is a breakthrough, it will be a big deal." Not only can we take color photos, but we can also take color films. Therefore, no matter how difficult it is, we have to break through. ”

"Okay! I urged them not to relax in this matter. Qingfengzi smiled and said, "Hehe! In fact, there is no need to urge them, these people are very involved in doing things, and they don't want others to interfere when they do things. Let's just wait for their results! ”

"Yes! Sometimes let them relax a little bit, and I think they are more creative. Zhang Zhimu said.

"That's right! One more thing is that there have been some breakthroughs. Qingfengzi said, "The fiber made of wood has made great progress. They alkalize the wood pulp to form alkali cellulose, and then react with carbon disulfide to form cellulose xanthan acid, which is dissolved in a dilute lye solution to obtain a viscous solution. Now they are trying to make acetate by wet drawing. If it does, it will solve the problem of our lack of fiber. ”

"That's great. At present, our acetate fiber still needs to be made from cotton. If your adhesive fibres can be made, we can use wood to process them and then spin them. By the way, there are inexhaustible reeds in Wuliangsuhai on the other side of the Hetao, which can be processed into fiber. Later, we built a fiber factory in Baotou, plus a textile factory. It was like making silver. The more Zhang Zhimu thought about it, the more excited he became.

Qingfengzi was also infected by Zhang Zhimu and said, "Yes! That's how I see it, too. If we exchange these wood and reeds for food, it will be of great merit to all generations. ”

Zhang Zhimu and Qingfengzi had a rare conversation for a long time, and they both felt unfinished. However, Yang Yulin called to say that Mr. Lu Bingyi had returned.

Zhang Zhimu hurriedly got up and said goodbye to Qingfengzi and said, "I'm sorry Master Qingfengzi, I'm going back to have a look." Mr. Lu Bingyi should have come back a long time ago, why has it been delayed for so long, there must be something, go back and see! ”
