Mr. Jia who was infected with the virus [Red House]

At the same time, the students of Jia Clan Studies have mastered the lithography technology and are working overtime to print the books in Simenguan.In order to make up 300 pages of content, Mu Xuan and others included the artificial egg hatching technology after Jia Dairu's consent, and added some additional experience of raising and training chickens.

They were born rich and noble, and they never thought of taking artificial egg hatching technology into their own hands to make a profit. Instead, they were complacent because their books contained artificial egg hatching technology that others did not know.I can't wait to tell the world that they can artificially incubate eggs and train chickens.

Thinking that the spring break is still more than a month away, Mu Xuan was a little worried that Yin would not be able to show off in front of others when he arrived.To this, Jia Dairu just smiled.

There is no such thing as imprinting. Compared with engraving, lithography saves a long engraving time. You only need to write on the slate with special ink, wet the slate or apply acid glue, and then apply ink to the slate. After pressing the paper, it is transferred to the paper.At this time, the reverse side is obtained, and then it is pressed firmly on the slate, and after the paper is peeled off, it is repeatedly brushed with water, ink, covered with paper, and pressurized, and the front side is obtained.

A few days later, the sample was printed, and when Mu Xuan took it in his hand, he found that it was in Yangwen, with elegant fonts, sharp strokes, and natural round lines, but the edges of the pattern lines were somewhat inconspicuously oil-soaked.It was definitely a good printed copy. Mu Xuan was overjoyed, and immediately held a meeting with the book. After counting the books that everyone needed, he directly contacted Wang Fan, the monitor of Class B of Jia Clan Study, through Jia She.

Wang Fan knew that it would be difficult for him to make further progress after he was admitted as a child. In addition, his poor family depended on having a stable income in Class B to live a good life. Therefore, he did not choose to study in Class A like Jia Wan Jia Dun, but stayed in Class A. Class B.

"We want to print 2000 more copies. Can we print them out before the spring break?" Mu Xuan immediately asked when we met.There are a total of 350 students in the Simen Hall, and everyone has a lot of relatives. Even if they only send their parents, grandparents and uncles, they need five or six copies.In addition, this is their first book, and they also want to collect one.

Therefore, 2000 copies is actually not much at all, and it is not enough to send at all. If he hadn't considered the printing capacity of the printing room, he would have ordered tens of thousands of copies.

Wang Busy nodded, "It's in time, but you have to pay the printing fee first, we can't afford it."

"That's natural."

Mu Xuan had no objection to this, paid the money quickly, and was about to leave when Wang Fan stopped him.

"I don't know if your son is interested in printing the pictures in color."

Wang Fan was a little hesitant when he spoke. They have always relied on the list given by their husband to give birth, but they cannot always rely on the husband.Therefore, he couldn't wait to recommend the chromolithography technology he developed to Mu Xuan.

The title of the book in the Simen Pavilion is Sichenpu, and there are many pictures in it. If it can be printed in color, it can charge a lot of manual fees.Wang Fan and others have always wanted to repay Jia's clan study and earn more funds for the clan study, and Mu Xuan just came to the door.

Mu Xuan's eyes lit up, but he asked unhurriedly, "Oh, how many colors can you print?"

Mu Xuan is not someone who has never seen the market. He has seen a lot of color engraving books, and he can understand it at least if he understands it very well. Over six colors.

If it's just the two colors of Zhu Mo, there is no need to do so much.

Wang Fan didn't know what Mu Xuan was thinking, so he thought for a while and said, "It's better to be within five colors. You have a lot of books to print, and you're in a hurry, so you can't be busy with too many colors."

Mu Xuan took a deep breath and asked, "How many colors can you print?"

Wang Fan was puzzled, "It depends on the paper. If the paper is good enough, it can be printed in ten colors."

In fact, chromatic lithography is overprinting, which has long been used in engraving, but lithography is not as uneven as engraving, and the paper is much less worn and can be overprinted several times.

Mu Xuan couldn't help showing a smile on his face, and patted Wang Fan on the shoulder regardless of his status, "Show me the sample."

Wang Busy went back and brought back a set of color lithographs, full of color and clear outline, more exquisite than the six-color printing he had ever seen.Mu Xuan took a fancy to it, "Okay, then print it in five colors."

Mu Xuan has already begun to imagine how surprised his parents would be when they received his book.

Wang Fan looked honest, but he was not good at negotiating prices. He pointed to the painting and said, "The color printing process is complicated, and the operator must have a certain foundation in painting. If you want five-color printing, the price is not cheap."

Mu Xuan frowned, "Is the Lord a person short of money? Report the number."

Only then did Wang Fan report the number cautiously, and Mu Xuan took a deep breath, but still said, "I'll send you the rest of the money tomorrow."

Class B took over a big order, and couldn't even attend class, wishing to work in the printing room 24 hours a day.Although the master of Jia Clan Studies doesn't care much about the grades of the students in Class B, he will never allow absenteeism, so he sued Jia Dairu.

"Everyone goes back to class. The stone slabs are all ready, but just brushing water, ink, etc., just come and teach." Jia Dairu is not one-sided, and there are only more than 30 students in class B, all of whom are his. Baby, how can they really be printers.

"But if someone else steals the technology..." Jia Dairu interrupted Wang Fan before he could finish speaking.

"Fart technology, do you need to hide things that don't have any technical content? If you have that time, do more research on the photography technology I mentioned last time."

Jia Dairu doesn't care whether the homework he assigns is beyond the outline or not. In his opinion, getting up early and taking black and white photos has no technical content.The students in Class B have studied engineering for several years, and it's time to produce results.

It's just that these students don't have enough imagination, so he has to assign tasks.

Sure enough, the faces of Wang Fan and others were wrinkled into a ball. The master's imagination is extraordinary, and it was too difficult for them to follow.

"Go back to class!" Jia Dairu scolded with a smile, "Those who didn't pass the Tongsheng exam have no right not to attend class."

Wang Fan shrunk his shoulders silently, and he had better not speak at this time, after all, he was the only child in Class B.

On the same day, Jia Dairu asked the Shi family to beg for help. There were thousands of servants in the Rongguo Mansion, and it was said that there were some who were idle at home and had no work. Borrowing dozens of them would not affect the operation of the mansion.

"After all, it's about ethnology. I'd better ask who in the clan has sons who are idle at home and don't make a living. If they don't have enough, they can make up for it by having children from the family." The Shi family should be more thoughtful. After all, there are some kids who don't make a living.

Knowing that Jia Dairu only cares about important people and doesn't care about others, Shi simply summoned Lai Tian's family and sent someone to inquire.The next day, Lian Jia sent a total of 35 people into the ethnology printing room with their families and children.

Wang Fan and the others were busy with one apprentice, but he was more careful and did not rush to teach the newcomers the core techniques of lithography, which were fat ink and acid glue.The servants of Ningrong Second Mansion are almost all big-mouthed. He suspects that he taught it on one side, and the whole capital on the other side knows the formula.
