If people in the world are used to it, and if it has always been this way, why should we change it? People in the world are still used to the lack of printing. This has always been the case, is it right? In ancient times, writing was written from top to bottom for two thousand years, is it right? In ancient times, writing was done from top to bottom.

For two thousand years, science has been kept in the corner, without pursuing the truth and following the rules. Is it right?

Obviously, after the invention of paper, the most efficient and convenient way of writing is from left to right and front to back. Why have we been writing in this awkward and inefficient way for two thousand years? Is it convenient from here?

This means that the innovative power of the Central Plains has begun to gradually disappear.

In the afternoon, the craftsmen made the calligraphy molds and sent them to the city lord's palace.

Two sets of subtitles, one with wooden boards and one with wooden characters.

The board is a jujube wood board with a few five-line concave characters engraved on it. Looking at the fonts, they are all reverse characters.

Li Mengxi took the ink and brushed a layer of ink on the wooden board. From this first step, Li Mengxi discovered the problem.

The problem lies in the ink and brush ink itself.

Because I used a brush to brush, I dipped in too much ink, so that after I brushed the writing board, there was a lot of wet ink. If I printed on the paper, it would be completely black.

The solution to the problem was very simple. Zhang Fei found a torn linen cloth and wiped the writing board a little. It was half dry and ready for printing.

Li Mengxi understood clearly that when printing, you cannot apply the ink just right. Most of the time, too much ink will be applied. The process is that every time you apply ink, wipe it with a dry cloth and then start printing.

.

Li Mengxi took a piece of straw paper and printed it on the typeface. He pressed it with his hand, but accidentally used too much force and broke the paper.

However, if you don’t press it, the paper will not stick firmly, and how can the words be printed quickly?

Li Mengxi understood clearly, oh, when it comes to the withering technique, it turns out that there is still a cover missing. With the cover, put the paper on it, press the cover down casually, the force is not too big, not too small, just right, printing is fast and smooth.

clear.

I read the paper over and over again, nodding my head as I read.

After finishing reading, Zhang Fei returned the lecture paper to Li Mengxi.

Li Mengxi read through the calligraphy and found that the calligraphy contained a few loose sentences from the Analects of Confucius. The craftsman didn't seem to know much about the calligraphy, and there were many typos in the dozens of words he wrote.

It can be seen from this that many Confucian classics are popular. Just ask someone who does not know how many words he has read, and ask him if he has read the book. If he has read the book, he must have also read the Analects, and if the person has only read one book

book, then this book must still be The Analects of Confucius.

The problems with this first piece of printed paper include, but are not limited to, the characters are too large, the fonts are not dense, the characters are unevenly engraved up and down, crookedly, and the characters cannot be engraved vertically, and they are printed with a gravure plate.

It’s not very clear. Many of the gestures are lumped together. Furthermore, it’s a problem with the paper. The ink is printed on the paper and smudges a lot.

It seems that if we want to popularize printing, we must solve the problem of ink smearing. Normally, it doesn't matter if we write larger characters, but printing has to print small characters as big as soybeans. The characters are so small that they smudge a little.

, the words can’t be seen clearly.

And since words are easy to smudge on paper, ink is also liquid, and ink smearing is also water smearing. Ink smearing is easy because it absorbs water easily. So how can we reduce the water absorption performance of paper?

Referring to the invention of the raincoat, it is said that the invention of the raincoat was caused by a rubber worker who accidentally stuck rubber on his sweater. He found that the rubber-stained area was waterproof, so he brushed the entire garment with rubber. The first raincoat was

This is done.

As for rubber, there is no such thing. You can use other glues. Most glues have some waterproof properties.

As for gum, there are peach gum, toon gum, and pine gum. All kinds of gum are common and the output is not low.

When spring comes, I'll look for some glue to see how to mix it into the pulp to improve the waterproof performance of the paper, so as to improve the pre-printing technology.
