Modern printing technology -- Opportunities and challenges

Music (art) : The art of expressing human emotions by auditory or visual means (dance). Music is recorded by musical scores, and dance can also be described and recorded by painting. There is still the problem of whether the information can be widely disseminated.

Obviously, before the invention of radio, television and Internet technology, printing was almost the only effective way to achieve the dissemination of information from a technical perspective!

(3) Printing technology and information visualization

Basic point of view: printing technology is an effective means to realize the visual expression of information.

Visualization originally meant "the method and process of constituting objective reality into an image of the human mind, or the visual representation of something that is not directly perceptible." With the development of computer information processing technology, visualization is also understood as the process of converting original analog data into images that can be displayed, the purpose of which is to transform information into a form that can be understood by human perception system.

The role of printing in visualization includes:

As far as the characters are concerned, the non-standard handwriting is changed into standardized printing, which ensures the visual reading effect of the characters.

To realize the integration of graphic information and improve the visual expression effect of graphic information;

To realize the presentation or reproduction of color information and improve the visual cognitive effect of image information.

The essence of printing can be summarized as follows:

In a visual way (text or image), the product can be reused by many people (the public), and the purpose of disseminating information to the audience (the public) is (to play) the visual perception function of human beings.

The understanding of information and information transmission (dissemination)

(1) There have been many studies and representations of the nature and definition of information

Wiener (founder of cybernetics) :

"Information is the content and name by which we adapt to and communicate with the outside world in the process of making this adaptation perceived by the outside world."

"Information is information, not matter or energy."

Shin Nong (Founder of Information Theory) :

"Anything that reduces uncertainty in a situation is called information."

The multi-layer meaning of information (typical point of view) : one is to eliminate uncertainty, the second is the ordering and organizational form of things, and the third is the representation and reflection of things.

(2) Personal views:

a. Information is the third objective existence independent of matter and energy, that is, the real world is composed of three elements: matter, energy and information.

b. Transmission of information is the basic element of the existence of information, without transmission, information will lose its meaning of existence. That is, information exists in transmission, and there is no information without transmission.

An immature consideration of the definition of information:

Information is the result of the information source's cognition of objective things, and through the transmission channel, it is used to guide the recipient's cognition of objective things.

According to this definition, information cannot exist independently of the transmission channel or even the recipient.

Based on the above point of view to understand the role of printing: printing is the information transmission channel, is the support of information existence.

Printing is transmitted by means of visual graphics, and transforming printing into graphic information dissemination is more adapted to the characteristics of the information age.

The "printing" mentioned by Dr. Sun Yat-sen actually means "information".

Confusing the concept of "printing" and "information" is in line with The Times, according to the personal definition and understanding of information, information can not be separated from the transmission process and independent existence, when printing is the main (or even the only) technical way of information transmission at that time, it is not wrong to think that "printing" is "information".

Thus, it is concluded that Dr. Sun Yat-sen is one of the earliest advocates of information theory, which early listed "information" together with clothing, food, shelter and transportation as one of the five essential elements of human life, as a basic need of modern society. And pointed out that human beings have no reason to progress.

Paper is the carrier of recording information ---- memory

Paper is a tool for information visualization ----- display

Printing is the process of information processing and transmission ----- processor

The combination of paper and printing: ancient information technology (IT), modern computer information systems
