The printing technique that Yunyi gave Xu Hui was not the original engraving printing, but movable type printing, which was more convenient and practical than the number of engraving printing.

This movable type printing technique is to make characters with clay, and each word is printed for a letter, which is hardened by fire to make it ceramic.

Prepare an iron plate when typesetting, relax the mixture of incense, wax, paper ash, etc. on the iron plate, and an iron frame is placed around the iron plate, and the word seal to be printed is placed in the iron frame, and it is a plate when it is full.

Then it is baked with a fire, the mixture is melted, it is combined with the movable type block, and the movable type is pressed on a flat plate while it is hot, so that the text is flat, and the printing can be carried out.

With this method, printing two or three copies is not efficient, and even the speed of manual writing is not as high, if the number of prints is more, dozens or even thousands, the efficiency is very high.

In order to improve efficiency, two iron plates are commonly used, one is printed, one is typeset, one is printed, and the other is lined up, so that it is used alternately, the efficiency is very high, of course, more iron plates can also be used.

Commonly used words such as "zhi", "also" and other words, each word is made of more than 20 words, in case there is a version of the repetition of the use, there is no preparation of rare words, then the time to come out, with the grass and wood fire immediately fired. The characters removed from the printing plate are put into a small wooden compartment of the same character, and the outside is labeled according to rhyme for easy retrieval.

Such movable type printing is very simple, and the cost is not high, in addition, Yunhua paper is thin and uniform, fine fiber, writing performance is much higher than Gaoxun paper, very suitable for printing.

The cost of Yunhua paper and movable type printing is not high, but the price of printed books is ridiculously high, and the purchase of the cheapest book is enough for an ordinary family to need for a month, which is destined to be a channel that brings huge funds to Yunyi.

However, it will take some time to print books, and the first batch of Yunhua paper of various types, equivalent to 100,000 sheets of one foot square, has been transported out of Yunhua County by Yun's caravan and sent to various parts of Zezhou.

Of course, it is impossible to sell paper only one foot square, this type of paper, people need to use larger paper when writing and painting, the larger the area of the paper, the more expensive the price, Yunhua paper is just made when it is a large piece of paper five feet square, and then cut into other specifications and models of paper.

In fact, the number of the first batch of paper is more, but some of it was intercepted by Yun's, after all, the quality of Yunhua paper is better than Gaoxun paper, but the price is very low, Yunyi gave Yun's price is 80 copper coins, there is such a good Yunhua paper, Yun Yuankai directly notified Yun's up and down no longer to buy Gaoxun paper, but to use Yunhua paper, and there is also a batch of Yunhua paper directly sold in Yunhua County.

However, there are relatively few people in Yunhua County who can use Yunhua paper, the population of Yunhua County is almost 100,000, and Yunhua County is barren and has few financial roads, so most of the residents in Yunhua County are ordinary people, and it is good to be able to eat well, how can there be spare money to buy Yunhua paper.

Yun Yuankai was not too surprised that Yun Yi's subordinates were able to do things like Yunhua paper, Yun Yi had brought too many changes to the Yun family since he recovered from his illness, Yun Yuankai and the others were already surprised enough, even if Yun Yi made any big moves, they didn't necessarily have too much surprise.

The prospects of the paper industry are very good, but Yun's is not short of money now, and this is Yunyi's private industry, and there is no voice to want to take the paper mill into Yun's at all.

Soon, the first batch of Yunhua paper was transported by Yun's caravan to various counties in Zezhou.

Yunhua Yun's family is in the middle and upper reaches of the Dali Empire's hundreds of thousands of families, in Zezhou, Yunhua Yun's status is also quite high, and the network is even broader, and it is very simple to sell the Yunhua paper in his hand, not to mention that the price of Yunhua paper is the same as that of Gao Xun paper, but the quality is more than one step higher than Gao Xun paper.

Yun's main industry is the salt industry, there are only salt shops in Zezhou, if you sell Yunhua paper in the salt shop, this will definitely become a huge joke, and even the reader will not go to the salt shop to buy paper in order to save face, Yun's people are not fools, they will not buy paper in the salt shop, but it is also troublesome to open a special store to buy paper, so Yun's people directly sell Yunhua paper to those places that specialize in selling pen, ink, paper and inkstone.

Clear-eyed people can see that the quality of Yunhua paper is much higher than that of Gao Xun paper, as long as the price is not outrageous, they are willing to buy Yunhua paper, after some bargaining, finally Yun's people will be a foot square Yunhua paper sold at the price of 1 silver and 25 copper.

Originally, Yunyi wanted Yunhua paper to be sold at the price of 1 silver, after all, the cost of Yunhua paper is very low, it can get enough income, and it can also squeeze the market of high paper, but I didn't expect Yun's people to give other stores the wholesale price of 1 silver and 30 copper, and in the store, these merchants directly marked the price of 1 silver and 50 copper for a foot square of Yunhua paper, but next to Yunhua paper is 1 silver piece of high paper, and a comparison between the two can see the huge gap.

Zezhou City, Yao's study.

A scholar in his right hand holding a fan and dressed gorgeously walked into Yao's study, and as soon as he walked into the study, the scholar said softly: "Boss Yao, give this son twenty pieces of Gaoxun paper, which is still the previous proportion." ”

In Yao's study, the slightly chubby Boss Yao was busy behind the counter, and when he heard the voice, he quickly looked up, but it was Zhou Gongzi, who often came to the store to buy the four treasures of the study, and Boss Yao hurriedly replied: "Zhou Gongzi, wait a minute, I'll bring you paper." ”

Before Boss Yao could act, he heard Zhou Gongzi's "huh", and Zhou Gongzi stared at the white and shiny Yunhua paper next to the slightly dull yellow Gao Xun paper on the counter.

"Boss Yao, what kind of paper is this?" Zhou Gongzi asked with a hint of surprise, and walked to the counter as he spoke, stretched out his left hand and gently stroked the Yunhua paper, as if he was caressing a beauty.

"Back to Zhou Gongzi, this is the Yunhua paper that just arrived today, it is said that it was just made in Yunhua County, the quantity is relatively small, and I only have three hundred pieces here." Boss Yao explained.

Zhou Gongzi gently picked up a piece of Yunhua paper and sniffed the smell of Yunhua paper with his nose, looking a little intoxicated.

After a while, Zhou Gongzi came back to his senses and said, "Good paper!" Good paper! Boss Yao, all this money was exchanged for Yunhua paper for this son. ”

But I saw Zhou Gongzi take the money bag and put it on the counter, there were dozens of coins in the heavy money bag, Boss Yao opened the money bag, and there was a white swaying in front of him, but there was a small piece of yellow in the middle, this is not a copper coin, the gold coin of the second yellow, orange and orange, a gold coin is enough to buy sixty or seventy pieces of Yunhua paper.

"Okay, I'll get the paper for Zhou Gongzi." The smile on Boss Zhou's face remained unchanged, but the movements in his hands were not slow, and after putting the money away, he turned around and took the paper to Gongzi Zhou.

[I don't recommend it next week, I'm depressed, there are too many gods who have opened books recently, and I don't have a round of recommendation on the street, so ask for some recommendation votes]
