Hearing Li Sicong say this, Li Bao immediately understood. The printing technology of the Tang Dynasty is still in its infancy, and even the extremely frivolous movable type printing has not been invented.

Li Bao's design of lottery tickets, flying money and treasury bonds are all color pictures, he wants to rely on the bright colors of the pictures, one is to prevent counterfeiting, and the other is to increase these tickets. The degree of recognition and dissemination of the data.

Except for the paintings made by only a few painters in ancient times, it was rare for civilian families to get such paintings. Li Bao wants to make it, and people can know that this is distributed by Li Bao's Xinglong Money Bank.

That's why he thought of coming here to consult with these professionals, and it was as he expected.

Li Bao was slightly disappointed, but he was also mentally prepared for this, so he said to Li Sicong: "This sketch was painted by me, I want to make a printing plate, but hòu prints tens of thousands, or hundreds of thousands, can you do it here?" ”

Li Sicong was taken aback by Li Bao's words. Is this Ji Wang Ye stupid, he just said that he couldn't print it, and he still had to print tens of thousands of copies or more, but he didn't dare to say that Li Bao had a brain disease, so he couldn't speak, just rubbed his hands vigorously.

Li Bao saw him like this and knew that he must be no longer good, so he continued: "Can I go behind you and have a look?" ”

In ancient times, the regulations of shops were almost the same, basically the front store and the back factory. So Li Bao proposed to go to the back to have a look, but Li Sicong didn't want to stop this kind prince, so he stood up and walked to the back with Li Bao.

When you arrive at the backyard, you can see a large courtyard of seven or eight houses, and there are about 20 craftsmen in the whole workshop, all of whom are working in an orderly manner, and they are not distracted by outsiders coming in. Li Bao is very satisfied with the work attitude of these people, rigorous and dedicated.

Li Baodu went to an old craftsman who was carving, and picked up a carved plate beside him, the knife work was neat, and the handwriting in italics was very pleasing to the eye.

In the bookstore, the number of people required for each process varies, and among these processes, engraving is the most important, the most tiring, and the least efficient, so the most people are needed. Among the more than 20 craftsmen in this Li Family Printing Workshop, nearly 10 are engraving. They vary in age, the youngest being in their thirties, and the older ones are already gray.

Looking at these rigorous craftsmen, Li Bao is very interested, because they are the people on the front line, and they can accept new technologies the fastest. So Li Bao clapped his hands at the craftsman who was carving, and then said, "Big guy, stop first, I have a few words to say." ”

The craftsmen who were carving at the desk heard Li Bao's words, raised their heads one after another, and saw a teenage nobleman who wanted to speak to them, they didn't figure out the situation for a while, but when they saw their own proprietor, they didn't object, so everyone looked at Li Bao quietly and listened to what this young nobleman had to say.

Li Bao asked Hu Sanbao to unfold the drawing paper again, and then Hòu told the craftsmen his request, and he hoped that they would give him advice.

But he was disappointed, these craftsmen were still silent, and Li Bao hurriedly said: "Don't you have any ideas?" If anyone can solve this problem, I'm in good hands! Ten dollars, as long as I can solve this problem, I will reward him with ten dollars. ”

Ten guan money is like a bomb, this entire Li family printing workshop has been detonated, ten guan money! The other craftsmen in the bookstore also gathered around after hearing Li Bao's reward.

In this late Tang Dynasty time and space, two yuan is enough for a family to barely survive for a year, and the senior craftsmen in the workshop only have five yuan a year, and most people live a year with two or three yuan.

This young nobleman took out ten yuan as a reward at once, which was really a big deal. Everyone theorized, and finally a young man with a full face said to Li Bao: "Noble, so-and-so, so-and-so...... An idea, don't know, when, when not to say. ”

Before he could continue, a big craftsman said to him: "Little Liuzi, what can you understand as an apprentice who brushes ink, these many masters don't understand, can you understand?" Don't offer treasures in front of nobles. ”

Li Bao smiled, waved his hand to stop the big man, and then said to the young man: "Little Liuzi might as well speak out and listen, since you are the first to speak, I have decided that no matter what you say or not, I will reward you with money." ”

Cai Xiaoliu looked at Li Bao in disbelief, and said in a trembling voice: "Always money? "He, the apprentice of ink brushing, is the lowliest worker in the bookstore, and the proprietor only covers food and lodging, and nothing else. Tired like a dog every day, money has always been an "astronomical" amount for him.

Li Bao looked at this weak young man, and his various reactions were all familiar with the ** who won the jackpot in the face of the year, so Li Bao nodded at him, "Yes, consistent money, whether what you say is right or not, I will reward you." ”

Cai Xiaoliu nodded excitedly, and then hòu said to Li Bao: "The pattern that the noble person wants, I think it is okay, you can carve out a complete image first, and then hòu is divided into blocks and colored separately, and then hòu can print the colored part." ”

Listening to Cai Xiaoliu's words, Li Bao's mind flashed, isn't this Cai Xiaoliu talking about the principle of overlay printing commonly used in the Song and Ming dynasties in later generations? If Cai Xiaoliu hadn't said it, he would almost never have remembered this set of printing.

Li Bao was extremely excited, he could remember this overprint printing, it was not that he was well-read and widely remembered, but hòu later generations had seen an online novel worn by a group of 500 people, where there was a pig's foot, and in ancient times to engage in propaganda, it was to use overprint printing.

I didn't expect an apprentice to be so smart, which really impressed Li Bao. Li Bao stepped forward and grabbed Cai Xiaoliu's hand and said, "Little Liuzi, what you said is right, this idea is correct." Great, I'm going to reward you with ten dollars. ”

Li Bao's words shocked Cai Xiaoliu again, he hurriedly pulled out his hand, and then hòu took the corner of his fairly clean shirt and wiped it on Li Bao's hand. He said: "If so-and-so's hands are dirty, don't stain the hands of nobles." ”

Cai Xiaoliu finished wiping Li Bao's hands, and only then did he remember that Fang Cai, a young nobleman, said that he would reward himself with ten yuan of money, he only felt a little dizzy in front of him, is this a dream, Fang Cai's consistent money is already a huge amount of money, and after a while, the consistent money has risen to ten dollars.

Cai Xiaoliu finally came back to his senses, and hurriedly waved his hand at Li Bao and said: "Nobleman, this money is too much, you can't ask for it, it's enough for a noble person to give a certain amount of money, and I didn't say anything." ”

Li Bao no longer cared about this simple young man, and said to everyone: "You may not know what Cai Xiaoliu is talking about, but I understand." He was a very smart kid and immediately got to the point. ”

The reason why it is difficult to print this color picture is that it is difficult to get the color on this picture, Xiao Liuzi said that it is colored separately in blocks, which is the principle of overprinting.

If you still don't understand, then I'll give you a method first, as long as you understand this method, then you can all understand this set printing.

"Let's take our common engraving as an example, if in the process of engraving, once a word is wrong, then the whole engraving will be discarded, right?"

More than a dozen engraving craftsmen listened to Li Bao's words, and each of them thought it was true, Li Bao saw the reaction of everyone, and then hòu continued: "If we change to another method, if all the characters are alive, then we don't need time-consuming and labor-intensive engraving, as long as the individual characters are arranged and typeset according to the draft, and then hòu printing is not simpler and lighter." ”

Li Bao's words opened a window for the craftsmen of the Li Family Bookstore like an empowerment, allowing them to see a brighter future.

Cai Xiaoliu had already recovered from Fang Cai's shock, and after listening to Li Bao's movable type printing, he thought a lot, and then Hòu asked Li Bao a question again. "Noble, how to fix the movable type in this movable type printing, and where does the character mold come from?"

Li Bao was impressed by this Cai Xiaoliu this time, this junior apprentice is really not simple, and his brain is turning so fast. The two questions asked were also about jiàn.

"Xiao Liuzi asked well, and asked the point, so I'll talk about the disadvantages of this movable type printing and the points of guanjiàn." Li Bao sorted out his thoughts, and then Hòu picked up the fast engraving plate in his hand and said to everyone: "The Guan jiàn of movable type printing is that the word is fast, and it is faster than engraving printing because it saves a lot of engraving time."

When typesetting, use a flat iron plate as the bottom plate, and then hòu sprinkle rosin and honey on the iron plate, these things will melt when heated, and after melting, you can stick the word mold one by one, and then hòu is flattened with a flat plate, and after cooling, this letterpress is become. Just print it directly, and when the book is printed and then roasted over fire, these molds can be taken down and used again. ”

As soon as Li Bao's voice fell, everyone exclaimed again, and the proprietor Li Sicong was even more excited, this method is so simple and efficient, if his own bookstore adopts this method, then the efficiency of printing books will be increased by at least ten times or more, then in Chang'an City, it will also be the Li family printing workshop. But before he was happy, Li Bao directly dispelled his thoughts.

"Although movable type printing is fast, the fatal thing is that the movable type is molded, and this problem is difficult to solve. Because the general material is very laborious to make the word mold, in addition, the woodcut word mold is not easy to engrave, the iron casting or pottery fan to make the word mold effect is not good, the only one to make the word mold of the best material is copper, but the cost of copper is too high. ”

So everyone was a little disappointed by Li Bao's fatality of movable type printing, but some people were happy, that is, those engraving craftsmen. Because they make a living from this, if this Li family bookstore switches to movable type printing, they will lose their jobs.

It's really a family happy and a few people are worried!
