The founder of modern printing was Gutenberg in Germany.

The age of Taming's lead alloy printing is 144o, about 4oo years later than the Bi Shengming clay movable type printing on Ming Da 6, but Taming's lead alloy printing, especially in the printing method, changed "brush printing" into "embossing", which laid the foundation for the exhibition of modern printing technology.

Gutenberg movable type printing mainly includes the following:

The materials used to make the movable type are lead, tin, and antimony alloys. Movable type made of this alloy is easier to form than wooden and copper movable type, easy to print, and has high print resistance.

The word box and copper mold for casting words were produced, so that the specifications of movable type were easy to control and convenient for mass production.

Oil-based ink was produced to improve the printing quality.

The manual vertical spiral printing machine method of making wood was changed to the "embossing" method.

It can also be said that this technology is a comprehensive progress that integrates alloy technology, machining technology, transmission technology and chemical technology.

If the people from the Hantang Group don't come, the people on this Mingda 6 will really start to go downhill.

Guden's movable type printing spread first from Germany to Italy, then to France, and then to 1477

By the time it reached England, it had already spread throughout Europe.

A century later, it spread to various countries in Asia, reaching Japan in 1589 and Ming Dai.6 the following year.

Gutenberg's casting, typesetting, and printing methods, as well as the spiral prototype printing machine he created, have been used in countries around the world for more than 4oo years.

During this period, the scale of the printing industry was not large, and the printing houses were mostly handicraft, and books were still relatively valuable.

There is a reason why Hantang Group has always put the printing business in the second stage.

In the research counterweight before the crossing, everyone denied the construction of carrying some printing equipment, not a single qiē, starting from scratch!

Of course, electronic information of various materials and drawings is still required.

The technicians shouted, "Let's usher in the age of lead and fire!" ”

In this way, everyone understands that this is engaged in lead printing.

It is precisely because the printing business has been postponed that it has been expanded, but it is relatively complete with equipment, and it has basically realized semi-automation, and the disc printing machine is used as a power source by the ball heat machine, and the casting workshop of the printing plant is equipped with an electric fan.

Secretary Yang Youxing said bitterly: "There is a 4oo degree lead furnace in the workshop, what is the use of you installing two hanging fans?" ”

As long as there is this word in the dictionary, it must be equipped with the "word mold" of this word, and the word mold is copper, so it is also called copper mold in the printing industry.

How many fonts do you need in a printing house? If it is English, only 26 letters can cope with all the words and phrases, however, Chinese characters are incredible, at least 3ooo characters must be there to basically solve the typography of the text jiàn version, however, 1ooo commonly used Chinese characters can also cover about 92% of the written information, a set of Chinese characters 35,000 characters, if you prepare 3 fonts is 3 times the number, the font size number, for example, the word in the newspaper is usually "5" characters, if there are five types, then 15 times the number.

This small printing plant of the Hantang Group is equipped with hundreds of thousands of lead letters. In addition to this, the small printing house had to be equipped with more than a dozen tons of metallic lead.

Of course, there are far more county-level printing houses in that world.

Secretary Yang Youxing didn't worry about this word mold problem, he didn't care whether Director Li Ziqiang was stamping or pouring Tao, it was okay to use CNC machine tools to engrave, as long as he had it, it was easy to say.

For the quality of the printed layout, the lead characters can usually only be used once, and the lead characters are scrapped and re-melted into lead ingots after printing.

The accuracy of the cast lead word size is very particular, and the error is not more than o.o1 mm, which is one-sixth of a head wire, otherwise, the typesetting of movable type printing will not spell out the square whole.

The quality and accuracy of the lead character depends on the mold, which is in addition to the above-mentioned "word mold" and "word body mold", which is also called "box".

As the name suggests, the box can be closed and opened, and that's how the mold works.

A lead character has six sides, and when the "box" is closed, the literal part of it is the font mold that has been closed, and the size of the font around the font body determines the size of the font.

The liquid lead nozzle of the casting machine is sprayed at the bottom of the word, and the liquid lead is sprayed into the mold core and immediately cooled into a lead word, and then, the "box" is opened, and the "tongue plate" in the word body mold will send the lead word out, and the word mold leaves the word body mold at the same time when the box is opened.

In this way, the words are cast continuously.

The casting machine is sent by Red Star Machining, hand-cranked.

The scale of the Hantang Group printing plant is small, there are only six printing presses in total, and the largest printing machine that can print "folio paper" is only one, but there are four hand-cranked casting plotters, which shows how important the casting plotter is.

But this question is not tired, but hot.

There is also a 400-degree high-temperature lead furnace in the workshop.

When Secretary Yang Youxing complained on the Internet, Xu Zhiming, director of Hongxing Iron and Steel Plant, laughed and said: "

Even if it's one of our smallest converters, do you know how many degrees?! ”

Secretary Yang Youxing doesn't know how many degrees, but it will definitely be higher than his own.

Secretary Yang Youxing ignored him, and just wanted to say, I am still in danger of lead poisoning here. But when he thought of the Budai Chemical Zone, he was speechless.

For a while, Secretary Yang Youxing was a little sad, you engineering students have suffered all kinds of pain and danger, why do you still want to pull yourself?

But everyone is busy, everyone has a part-time job, it's easy to have a day off, and everyone is happy, forget it, it's not the same as them, everyone contributes.

Fortunately, the hand-cranked caster does not have high requirements for the caster, as long as the careful operation will not produce "splash lead", the liquid lead temperature is as high as 3oo degrees Celsius, when the "word body mold" is close to the liquid lead nozzle, if the action is not coordinated, there will be liquid lead splashed around, liquid lead is burned on the hand at least three degrees of injury, splashing on the face of the person is simply disfigured.

When the technicians were teaching Mingren labor jetting, Yang Youxing's secretary was far away, and he was really afraid.

But those Ming laborers learned quickly, and they were originally from small tinsmiths and the like.

In addition, this waste word furnace also has to master a certain metal smelting technology, the material used in the lead word is an alloy, it also contains tin and metal antimony with lead as the main body, and it is necessary to adjust its alloy composition through guò smelting to solve the finish and hardness of the word.

This does not have to be worried about Secretary Yang Youxing, there will be a special technician to serve in the factory at that time, a phone call.

The lead printing machine of Hantang Group is a disc printing machine.

The reason for using it is that this thing has a very simple structure and is very durable.

When it was delivered, Director Li Ziqiang personally demonstrated the operation, and Secretary Yang Youxing understood it at once.

This is the manual rule of using a fixed size wooden board to transport the paper, as long as the paper is smoother when it passes through the guò.

There is also a nut on the machine to adjust the amount of ink, whether it is thick or light, adjust it yourself, and that's it.

The largest disc printing machine weighs 800 kilograms, is an 8-carat printing machine, and has a maximum size of A3 paper.

The parts of the machine are basically steel castings that are not easy to break, and the quality of Eucommia ulmoides is not bad.

Director Li Ziqiang patted Secretary Yang Youxing's shoulder cordially at that time and said, "This equipment is simple and easy to operate, and it is suitable for you to study and use it with Mingren technicians and make progress together!" When the time comes, we will be free, give you better equipment, and the board believes in your abilities! ”

After Secretary Yang Youxing was excited for a long time, he felt that this was not a praise.

The disc printing machine is driven by a spherical heat machine, which makes it impossible to print fast, but fortunately, the demand for printed matter in this period is not large.

The paper of Hantang Group is the best paper in this time and space, whether it is in the compactness of the paper, or in the whiteness, smoothness or ink absorption, it is the best.

Budai Chemical Industry Zone sent printing ink here, and until now, Secretary Yang Youxing has not remembered all the ingredients in it, but he knows that there is flax oil in it.

At first, I printed some forms, then complicated forms, and finally I was able to print the textbook of Akatsumi Elementary School.

Before Secretary Yang Youxing could get excited, Principal Luo Lang called and said, "Secretary Yang, the female calligraphers you have there are all provided by our Lanxiang School, so it's time to print our textbooks first, right?" Push from other schools. ”

Secretary Yang Youxing said: "We can't print the textbooks you sent, let alone the photos, the illustrations can't be printed, and they can't be engraved." ”

Principal Luo Lang asked curiously, and said, "Can't you print a photo with a lead print?" ”

Secretary Yang Youxing said honestly: "It can't be printed, I was suspicious at the time, but then I understood it when I looked at the equipment, or you would know it at a glance." ”

Principal Luo Lang smiled and said, "No, I heard that you are a place where the mafia is born." ”

After saying that, she hung up the phone with a smile, but Secretary Yang Youxing felt sorry for herself.

Look at it, it's all famous, I used to be a pair of white hands, look at now, I've become a mafia!

Because of the frequent contact with ink and lead characters at work, the people in the printing house are often full of black oil, which is very difficult to wash, wash with brown silk and soap, often wash - wash not clean, - generally have to wash several times, when it comes to internal urgency, there are often people - vice while washing their hands and stomping their feet.

If the work is tense, Secretary Yang Youxing has to go into battle in person, so these hands can't be seen.

He just wanted to complain on the Internet, and then remembered the sand turning workshop of the Red Star Foundry, forget it, it is far dirtier than his own here, and if he complains about his work, he may be sprayed.

This production has just accelerated, and Chairman Wu Dapeng opened his mouth to ask for a newspaper.

It's easy to say anything about the manuscript, and Secretary Yang Youxing is invincible.

News, newsletters, editorials, interviews, whatever the story is serialized, don't be afraid of anything!

But he was afraid of typography. In this era of lead printing, editors have steel rulers, stacked sample paper, and accurately convert the text into the number of lines on the pattern according to the number of words.

The most difficult thing to be an editor is to accurately grasp the number of words in the manuscript, and quickly synthesize the number of lines in the layout.

Fortunately, this newspaper can only be opened in eight, and there are fewer manuscripts

Secretary Yang Youxing asked Chairman Wu Dapeng aggrievedly, saying: "Isn't the newspaper the next stage?" This political task must also conform to the laws of the exhibition—"

Chairman Wu Dapeng sighed and said: "I know that you have worked hard, if you conform to the laws of the exhibition, you will not be called a political task." Now public opinion in Xiamen is a little dissatisfied with us -- we don't know that the north is going to be right after winning two battles, and we still have to step up our own policy propaganda and not be misjudged by the other side. ”

Chairman Wu Dapeng's praise almost made Secretary Yang Youxing's tears fall, what are you afraid of? Just let the top leaders know.
