The words are divided into two ends, and after talking about Sun Shangxiang's nonsense, let's take a look at Tian Fan again.

That night, after Tian Fan rushed to the manor in Lu County, he temporarily suppressed the feeling of hunger in his intestines, and led Tian Long, Tian Hu and others to hurry to the workshop by Surabaya.

There are two workshops that Tian Fan attaches the most importance to, one is a papermaking workshop and the other is a printing workshop. The reason why Tian Fan was in a hurry and rushed here without even saying hello was because Tian Hu reported that the key technology of the printing workshop, that is, movable type printing, was finally successfully studied!

It lasted more than eight months, and when papermaking was about to succeed, printing was put on the agenda by Tian Fan and began to be studied. However, the seemingly simple printing technology has made the craftsmen anxious, and several key points have not been able to make breakthroughs, so until the papermaking has been successful for more than three months Today, Tian Fan still has not announced to the world that the Tian family has produced a new type of paper! Papermaking, without the accompaniment of printing, is really not perfect!

Today, printing has finally succeeded!

Tian Fan hurried to the printing workshop, and he didn't see the strange eyes of Tian Long and Tian Hu at all. In fact, with his current excitement, even if he sees it, he won't think much about it.

Thirty steps away from the printing workshop, Tian Fan smelled a foul smell coming to his face.

He couldn't help frowning and said, "What's the matter?" Why is it so smelly? ”

Tian Long and Tian Hu knew the source of the smell, but they didn't understand the reason, and happened to see an old craftsman in the workshop in front of them, Tian Hu hurriedly beckoned: "Old Hu, come here, the son is here, come over and salute!" ”

The craftsman surnamed Hu is about fifty years old, with gray hair and beard, slightly chubby, a natural baby face, smiling before speaking, looking at the way he walks, his body is very tough.

When Tian Fan saw him, he hurriedly beckoned and said, "Old Hu, come here!" ”

This person's name is Hu Rao, and he is the head of the craftsmen who are specially responsible for the two workshops here after Tian Fan was selected from dozens of craftsmen who have papermaking operations. His hometown is near Chang'an, and his ancestors made Cai Hou paper.

As soon as Lao Hu saw Tian Fan, he hurriedly ran over, smiled and saluted: "I've seen Gongzi!" Hey, Childe, got the good news? The mouths of the little dragon and the little tiger are fast enough! ”

Tian Fan nodded and said, "I know, why don't I come over?" Well, let me ask you, why does this workshop smell so much? That's not good, the craftsmen are prone to physical problems! ”

When Lao Hu heard this, he hurriedly complained: "Son, you really don't have a backache when you stand and talk!" Do you think I want to? Do you know the process of making paper? Do you know how long the materials needed to make paper need to be soaked before crushing? Can he not stink after soaking for so long? How can you make pulp if it doesn't stink? How can you ...... if it doesn't stink?"

Lao Hu is a broken mouth, especially after receiving the heavy responsibility given by Tian Fan, this guy's identity has skyrocketed, and the problem of broken mouth has become even more serious. Tian Fan couldn't help but roll his eyes and said, "Okay, okay, can't I be wrong?" You shut up! ”

Lao Hu hurriedly shut up, but he still couldn't help muttering: "It's spring now, if it's summer, the taste will be even greater!" ”

Tian Fan naturally heard it, but he didn't care. With a slight sigh, he said: "I will help the craftsmen order a batch of masks, and let them all wear them in the future, maybe it will be better." After a slight pause, Tian Fan continued: "In addition, the weather is hot in summer, and it is even hotter after wearing a mask. Also, twice a year, I ask the craftsmen to have a doctor to check their health, and if they are sick, they will be cured, and it is better if they are not sick! Well, that's all I can think of for the time being, and I'll add it later! ”

Lao Hu was moved in his heart, nodded, hugged his fists and said: "Childe is kind, little old man thank Gongzi on their behalf!" ”

Tian Fan bowed his head slightly and said, "Let's go, let's go to the printing workshop to have a look, and then go to the papermaking workshop to have a look!" ”

The crowd accompanied him to the printing workshop.

The printing workshop and the papermaking workshop were less than ten steps away, but as soon as they arrived near the printing workshop, a strong smell of ink and the fragrance of something unknown covered up a lot of the stench emitted by the papermaking workshop, and the smell was no longer so unbearable.

It was getting late, all the craftsmen had gone home to rest, and the printing workshop was empty. Lao Hu took Tian Fan in the workshop, from molding, to typesetting, to printing, etc., and looked at every process. It didn't take long, he could only just look at the flowers, and Tian Fan didn't ask about many things, because what he wanted to see most was the finished product! Eventually, the crowd came to a huge table. On the table are a few movable type plates that have been arranged, and some pages that have just been printed.

Each movable type edition is about the size of a large thirty-two pages, each page has one hundred and ten words, looking at the metallic luster emitted by those movable type molds under the reflection of the torches, looking at the hundreds of sheets of paper that have been printed on the desktop, Tian Fan picked up one, carefully stared at the clear words on it, and was speechless for a long time.

How important has a seemingly simple printing technique played in the development and continuation of human civilization? I'm afraid no one can say clearly! With the printing press, the cost of book retention has been reduced, reducing the possibility of books being lost. With the printing press, it was no longer an impossible dream for ordinary people to want to read, and knowledge was able to reach the masses instead of being owned by a few. With printing, the crystallization of culture and the wisdom of predecessors has made it easier to pass it on, and so on......

After a while, he let out a sigh of relief and said, "Lao Hu, I remember that there were a few key points in the past, which have not been solved, how did you solve them?" ”

Lao Hu's face was very weird, he shook his head with emotion, and said: "Childe, printing has not been completed, in fact, there are three major problems that cannot be solved. First, the hardness of the font is not enough. According to Childe's suggestion, we use lead that is soft, rust-resistant, and easy to melt and cast. However, the lead material is too soft, and after printing many times, there will be very serious wear. Second, the problem of printing ink. The quality of the paper we produce is not up to the flatness and smoothness that Childe requires, and it is slightly rough, and the ink spreads when it drips on it. Well, if it's handwritten, it doesn't matter, because the handwritten font is larger, but we naturally want to print the font as small as possible, so that many strokes can't be seen clearly, and words with similar shapes can't be distinguished at all.

"Third, and the most important problem, after the typesetting of the word mold, because the word mold can not be exactly the same size, although the difference is very small, and even the human eye can not distinguish, but in the process of printing, there will be some word mold printed, some are not printed, or, the printed word clarity is not the same."

Tian Fan nodded and said, "Well, I know these three problems, how did you solve them?" ”

Lao Hu sighed and said, "Childe, the first problem, that is, the hardness of the character mold, we added some tin to the soft lead, so that the hardness of the character mold is enough." The second problem is the problem of printing ink...... Childe, the little old man has lived for more than fifty years, but ...... I never thought that ink is not necessarily made of ink with water......"

Tian Fan was stunned for a moment and said, "What do you mean?" Lao Hu, you should say it quickly! ”

Lao Hu nodded, let out another long sigh, and said, "Childe, someone suggested that since the ink made of water is too thin and easy to spread on paper, why not use oil?" Childe, don't you know, it's this sentence that makes us suddenly enlightened. After that, we studied the use of oil instead of water to formulate printing inks. From the fineness of toner particles, to what kind of oil should be chosen, the ratio of several oils, etc., we have overcome the same problems, and finally, we have studied the ink used now. ”

After a slight pause, he continued: "This kind of ink is relatively viscous, but it does not stick to the paper, it will not have any inconvenience in printing, and it is not afraid of cold weather in winter, and it will not freeze. And we have experimented, printing next to the stove, the effect will not change much, it is really a rare good ink! ”

Tian Fan couldn't help but secretly applaud, this idea is quite good!

He nodded and said, "Well, this problem is well solved!" Well, how is the third question solved? ”

Lao Hu said: "Actually, it is also a common ...... Or that there's no mystery to it. In the frame where the font is placed, that is, on the master of the printing plate, the melted pine resin oil is inserted before the font is placed, and then the font molds that have been arranged in order are inserted. At that time, find a hard and flat wooden board or iron plate, press the mold, and force it evenly, and after a period of time, wait for the pine oil to condense, and the top surface of the mold ...... That is, the side to be used for printing, that is, it is completely flat. After using this method, the font mold is evenly stressed during printing, and the color of each word is not too dark or too light, and all the words on the whole paper are equally clear. ”

Tian Fan couldn't help but shout: "Gao, haha, it's really smart!" ”

He looked at Lao Hu and asked eagerly, "Lao Hu, who came up with these three ideas?" It's just amazing, haha, take me to meet these masters! ”

Looking at Lao Hu's face, he knew that this could not be his initiative. As far as Lao Hu's temperament is concerned, if he was the first to do so, it is estimated that this guy would have gone to invite merit by himself!

Lao Hu looked at Tian Fan with strange eyes, and after a while, he said, "These three ideas were come up with by the same person, but ...... Childe doesn't know? ”

Tian Fan was stunned for a moment and said, "What? What do I know? ”

Lao Hu was a little stunned, and after a while, he said: "Childe, you better go see her tomorrow, that master has been directing us to do these things these days, and he is really tired." This afternoon, after the first pages were printed, she went to rest, and in the afternoon she couldn't wake up when she ate ......."

Tian Fan rolled his eyes and said, "Old Hu, I can visit him again tomorrow, but now, can you tell me who he is, the people there, and how old he is?" Also, what does he like? What is the personality? Wait, wait, and so on, tell me that since you're going to visit someone, you have to know something about them, right? Such a master must have a temper, if he is offended, it will be a big loss for our Tian family! ”

Lao Hu smiled, and after a while, he stopped laughing and said, "Childe, what you call the master...... That person is a person from Xiangyang, fifteen years old, surnamed Huang Mingshuo and Yueying, and is the only daughter of Mr. Huang Chengyan in Xiangyang. Hehe, as for the rest, I guess you know! ”
