Some stories on the back of A4 paper

@ Big understand son: Life again ordinary but A4 paper, behind the story there is a basket, and are about our design, but also involved in the gold ratio. Today this article has a lot of graphics and text commentary, to help you raise a high-end posture.

This article for the author authorized excellent release, without the author's own authorization do not reprint, thank you:

The author micro-letter public number:H5 advertising information Station , welcome attention yo.

In fact, for most people, the more common things are, the easier it is to ignore them automatically ...

Let's say:

Have you ever wondered why you should call A4 such a name?

Why do we have to 210x297mm so big,

Direct 210x300mm not good, not remember, also bad calculate ...

Why can't it be square? It's not convenient to stack airplanes!

Why not a little bit longer, I also want to be a one-time tablecloth with Na!

These questions perhaps you will feel the special serious, the special tricky ...

However, not many people answer, and the answer two or three sentence still can not say clearly!

Well, let me try to summarize the content in my own way, I will ignore many details and complex data, and try to convey the message as simple as possible.

　　What is standard paper?

The industrial age has brought the symbol of the industrial age, that is standardization!

And our daily use of paper can not escape the fate of bondage, paper is like a screw as the Germans in the 1820s into their own industrial standard system-German industrial standard ratio (DIN)

Of course, that would not be the world standard. But as soon as it appears, the back is particularly fast, and so many different cultures of foreigners can easily accept the German standard!

In the continuous evolution, the international standard of paper formed today's three major categories, and was given three high-end atmospheric internationalization of the name, is a paper, respectively! b No paper! C-Number Paper!

One of the paper, the most widely used!

　　So, what is paper a?

Paper A is actually a batch of different sizes of paper, it carries the number can be understood as the number of fold, and A4 paper is actually A0 paper for the fourth time folded paper size, so gave it a look academic and straightforward name--A4

From the paper's lot number, it is very international, very standardized,

But when you see those size numbers behind you!

Ah yo ~ is not all see dizzy, how does not have the standard feeling na?

It's like a made-up, scribble, and especially bad memory.

Why is that?

Directly from the whole set of paper A, as if it followed a certain proportion, then this ratio is?

　　About the proportion of paper

In the 19th century, some scientifically based experiments were carried out by people without artistic bias, and they are said to have found an objective answer to what is the most beautiful proportion, the proportion of which we know the Golden Ratio (1:1.618), although early in the Renaissance, The artists began to divide the picture with the golden ratio, but it was not until the 19th century that people began to ascend to the stage of scientific theory, to re-examine and study.

And the concept of beauty in different periods will have different changes, when the bulk production of this way continuously permeate the early 20th century, the game of functional and aesthetic research began to appear on paper.

For paper, design pioneers think that paper not only have absolute practicality, but also have aesthetic feeling, and the way to obtain beauty in that era, from the imitation of natural organic form has begun to turn to the science and technology and industrialization of worship, in order to make paper with functional and aesthetic dual attributes, They found an interesting bonding point in traditional aesthetics and emerging industrial aesthetics,

　　This bonding point is- - ratio

For most people, our perception of form is emotional, it does not depend on any composition, even in the industrial society, people can not find the answer in an exact way, why do we see the golden ratio will produce visual pleasure, why it is so engaging ( Is it because people in the period of classical art have been tired of the middle axis symmetry of all the aesthetic things, of course, this is just my little guess it is like a classical aesthetic essence of the Golden Division ratio--1:1.618,

And the really amazing things are going on, and when people use the science of proportion to print, they create a stunning achievement on paper!

They actually use math--they get a lot of different gold ratios!

However, the problem comes again, so many proportions seem perfect, we have to choose that?

is a historical precipitation of the gold ratio of 1:1.618

Or what percentage? How do you judge this?

For this question, if you judge it purely on the scale of beauty, you can never get the answer, but do not ignore the final standard function, the size and proportion of paper itself can not produce the judgment of the functional, and decide the final rendering effect is often, layout, paper, printing, elements, and even production costs! It's the money. !

After some accumulation of struggle and game, people finally found a proportion, and this proportion in the next century, changed the world we are familiar with.

　　German industrial standard ratio

In these golden proportions, there is only one proportion that is particularly noticeable, and it is

So, where are the 1:1.414 advantages?

Industrial production requires standardization, and for paper A, the meaning is more far-reaching ...

1:1.414 is the most suitable for the standardization of the proportion of paper models, to A0 to A6 this interval, a0=841x1189mm area is just 1 square meters, the long side of the fold and will not change the original proportional relationship, and in a large number of production process will not cause any waste of paper.

　　when the A4 Fold, it will produce A5 .

Although the integer good memory, but it can not be an approximate value of 5:7 is 1:1.4 of the substitution, because of the error in the calculation of the fold, it will bring a lot of complex scale calculation problems, and the use of paper A will not bring any calculation problems, it can be in the factory tailoring to the maximum extent to avoid waste, Not even a waste! has a very powerful function! The traditional aesthetic precipitation of the gold ratio of 1:1.618 of the Division and other paper ratios can not meet this attribute.

Perhaps because of the double demand for beauty and function, therefore, it was created, with the German industrial label scale of a paper, so it can not be square or long, leaflets can not be an integer or approximate value, intuitively, it is not standardized, but, it is in fact, is a deep level of standardization!

　　So, is there any limitation?

To tell it so marvellous, it means that it is no problem, airtight that, of course not!

The biggest advantage of paper A, the actual is its biggest problem, like the modern design later exposed the same problem, inflexible, rigid, no due personality, which is also a paper problem.

Especially for books, when the concept of a cross page appears, then a paper for two of the scene of mutual existence, completely lost its own proportion of aesthetic advantage, with this problem you may find that directly using 1:1.414 of the paper as an inner page, you make the book will lose the original proportion of beauty, And for personalized pictures, collections, and brochures, the true individuality of the latitude and proportion is very useful, because they can be a good reflection of what you want to convey the meaning of the content of the emotions.

So most of the other gold ratios have been applied to the book field.

And these are the international standard of paper can not be done, it is more like a proportional unit, but it is not, and modern design has the same problem, but until today, it is still the most appropriate answer, even now the paper media is constantly marginalized by digital media, but people's reading habits still follow the rules of its creation.

Accidentally wrote more than 2000 words, actually this is a can also delve into and refine the topic, although it is just a simple paper, but, generally speaking, get a simple thing, need a series of complex attempts, I believe many people will agree with this.

If you are on the scale of the art by me, then must look at "Layout design grid composition" This book, in the grid and paper I read the book, I think this is the most praise!
