Chapter 8 has goods in the belly

It's not that she's cornered, plus Su You has shown a talent for things, and what she did makes Banniang feel amiable and reliable, and now she has broken her predicament with another word, and it is estimated that Banniang will not nod to Su You.

After all, no matter how smart he is, Su You is also a child who is only six years old in the eyes of Banniang.

Su You shook his little head and thought about it, and said seriously: "You have to read it before you can say it." Shall Banniang take me to the workshop to have a look? ”

Banniang nodded and said, "Okay, I haven't been out for a long time." ”

went to say hello to Cheng Wenying, and the two went out of the printing workshop.

Today's women are not as good as the later period, they pay attention to the door and do not go out of the second door, locked in the boudoir, and the autonomy of women is still relatively high.

Shiyue called a small sedan chair, Banniang entered the sedan chair, and said "South Gate Shuijing Lane", and the sedan chair man stepped in response.

All the way to a small room, open the door, you will see all kinds of woodworking tools, as well as a table full of engravings and movable type.

Banniang's expression was gloomy, and after looking around, she said, "After I got sick, I dismissed all the workers. ”

Su You was not polite when he entered the door, he looked at all kinds of tools and word prints, and then randomly spelled out a word plate, picked it up and looked at it carefully in the sun, and said: "Compared with the engraving version, the gap between this movable type version is inevitably a little big." ”

Banniang's face was slightly red, and she nodded: "Yes, Banniang ignored Meng Lang." ”

After speaking, he pointed to the printing plate and said: "Uncle Xiao, you see, the engraving is written on the plate, the font size is the same and the engraving is done in one go, so it is very even, and the words can take care of each other." And the printing plate is a word, this movable type and other movable type do not correspond well, and it is inevitable that there will be uneven size. Within a line, not only the size of the words, but also the thickness of the strokes are sometimes difficult to consistency. ”

Su You said, "Wait, I'll write them down one by one." ”

After Su You grinds the ink, he finds a blank piece of printing paper and writes "1. Font problem." At that time, Banniang's eyes lit up, and she couldn't help sighing: "The word Uncle Xiao is so noble." ”

Su You is quite modest: "Calligraphy, I'll ask you for advice another day, Banniang, you continue." ”

Banniang nodded and said, "There is also the uneven color of the ink." Because of spelling typesetting, there will be uneven layout, so when printed, the ink color will be light and heavy, and the shade will be uneven. ”

Su oil added another strip of ink to the paper.

Banniang continued: "The layout is not neat, sometimes it is not straight, some words are arranged crookedly, and even individual words are inverted or horizontal. ”

After speaking, he pointed to the corners of the printing plate: "The corners are spliced, and it is impossible to fit them tightly, so there will be gaps, staggered and other phenomena." ”

"In addition, the line boundaries will become intermittent, and the line boundaries of movable type will also be spliced, so they will also be uneven, so that the ink will be uneven, and there will be intermittent and intermittent phenomena."

pointed out a few more details, and Banniang said: "After this incident, Banniang knows that everything in the world is not taken for granted. ”

Su You nodded and said, "This is easier said than done. Now let me summarize. ”

After speaking, he pulled a few lines on the paper and gathered them into a point: "The reason for these problems lies in the size and process of the word print, which is caused by the inconsistency of the craftsman's craftsmanship." ”

Then he pulled a few more lines: "These are caused by the deformation caused by the expansion of the wooden seal when exposed to water." ”

Then the two of them summed up the problem of the size error of the word print, the error of the line line boundary, the problem of fixing the word print, the problem of height error, the problem of storage and typesetting retrieval, and the problem of review......

Some of the problems were come up with after thinking about it for a long time, and some were discovered by Su You.

Banniang took Su You's list, and her tears couldn't help it: "I can't imagine that there are so many mistakes, Banniang really sits in the well and watches the sky, and it is easy to see the world." Eat the bitter fruit today. ”

Su You said: "Knowing the problem, then we will solve it step by step, and when all the problems are solved, this new printing technology, can be flexibly imposed, will not break, and is definitely a big breakthrough in the printing industry." In fact, things can already be done, and all these problems are just a matter of beauty and delicacy to put it bluntly. ”

"The first thing that needs to be solved is the material, wood does not seem to be suitable for movable type printing now, Banniang, have you tried other materials?"

Banniang "ah": "Other materials? ”

Su You said: "Yes, the ancient ancestors used jade seals and copper seals, and now we use them back, isn't it?" However, the jade seal copper seal is difficult to engrave and cast, and if you use pottery, well, it is almost feasible, I suspect that Bi Sheng used it as a pottery character, and only in this way is it not easy to deform. ”

Banniang thought for a moment and nodded: "Then let's try?" ”

Su You said: "Professional things need to be handed over to professionals, do we have craftsmen who fire ceramics in Meishan City?" ”

Banniang said: "The Shi family has several porcelain shops, but I know them. ”

After speaking, he burst into tears and smiled: "The son is the younger brother, and the one that his mother arranged for him is the little lady of the Shi family, but he hasn't passed the door yet." ”

Su You saw Banniang smiling, and his heart was a little more relaxed, and said, "That's easy, let's go and see it now." ”

Banniang looked at the sky outside the door and said, "It's too late today, the ceramic workshop is outside the city, and there are only stores in the city." ”

Su You nodded: "Then let's continue to discuss, in addition to the materials, the rest is basically the problem of poor work, then we need more accurate measuring tools to ensure that each impression is generally correct." ”

"Font problem, then you have to find a full-time custom, it is best to be carved by one person, if one person is too demanding, it is best to be a family, the craftsmanship is in the same vein, the font is not far apart, this is the strength of the Cheng family, the problem is not big."

After speaking, he persuaded Banniang: "Banniang, this is a big deal, it's not good for a person like you to tinker with, every step of the experiment, you have to give Ming Cheng Tai and the master, as well as your husband." ”

"You are the daughter-in-law of the Cheng family, you can't let them think that you are an outsider, and it is better to discuss everything."

Banniang was smart, a little clear, nodded and agreed, but in a blink of an eye, she was worried: "Now it seems that the most difficult problem is the process error you said." This requires too much craftsmanship from craftsmen, and in Meishan City, I am afraid that there are no such craftsmen with excellent skills. ”

Su You smiled: "This is the easiest thing for me, the Shi family outside the village has a set of "Nine Chapters of Arithmetic Notes", when I don't have other books to read, I just read this, I feel that the method inside is enough to solve this problem." ”

Banniang exclaimed: "Really? ”

Su You thought about it seriously, quickly sorted out his thoughts, and said: "Banniang think, the size of the word mold, the main thing is that there is no enough fine measuring tool to measure, the book prints large characters, the font itself is not more than half an inch, one-tenth of an inch is a minute, one-tenth is divided into a centimeter, a centimeter is ten millimeters, a millimeter and ten filaments, well, if there is a ruler, it can be accurate to the millimeter, use it to measure the impression, discard it if it does not fit the size, or polish it, so that the printed plate can be tightly fitted, right?" ”

In the Song Dynasty, one inch was converted into a metric system of 30.7 millimeters, and that centimeter was 0.3 millimeters, which was already the concept of a centimeter.

Banniang thought for a while, shook her head and said, "Accurate? So how can you see the dense scale? ”

Su You said: "So you have to be tricky." Let's go, go back and get this done. ”

Back at the bookstore, Banniang summoned a group of craftsmen and asked them to cooperate with Su You.

Moments, rulers, and rules are all ready-made in the bookstore's workshop, and Su You found a large paper to print the book and prepared to make a drawing.

However, to be accurate, this one has to be fine, and in the end, Banniang found out the small pen of her own pen, which can be regarded as barely suitable.

When the craftsmen heard that a five-year-old gentleman came to the Su family and wanted to make a measuring stick that was accurate to centimeters, they couldn't help but shake their heads, which was clearly impossible.

Su You didn't care, and began to draw with a ruler, and began to explain while drawing.

First, draw a horizontal line on the drawing, and then draw a vertical line by using a compass to determine a point on each side of the line.

The craftsmen knew it, but a five-year-old kid knew how to get a vertical line in this way, and the craftsmen couldn't help but be impressed.

But not surprisingly.

Next, Su You takes points on vertical coordinates with a compass and a ruler to draw a right-angled triangle with a right-angled side length of one foot.

Not bad, very standard and beautiful, the craftsmen continued to nod.

Next, when the magic time began, Su You discarded the original inch marked on the ruler, disgusted that it was not fine enough, but then drew a random ray under the triangle with a right angle as the apex.

Then use a compass to divide the rays into ten equal segments, use a ruler to connect the point at the end with the forty-five-degree vertices of the adjacent sides of the right triangle, and then use the parallel line relationship of this line to divide the right angles into ten equal parts.

As soon as this hand lit up, the craftsmen immediately realized the value, and this hand method can accurately divide a straight line of any length into any equal parts! This little gentleman definitely has goods in his stomach!
