Today, humanity has entered the 21st century. Modern information technology includes microelectronics, computer technology, multimedia technology and information processing technology, and international Internet technology. Knowledge economy refers to the economy based on the production, distribution and application of knowledge and information. It is an economy composed of three major elements: knowledge innovation, knowledge dissemination, and knowledge application. As a printing industry that disseminates knowledge and civilization, it has determined that it is an important driving force in the era of knowledge economy.
I. The third leap in the knowledge-based economy and the printing technology revolution Since the early 1990s, when the UN Organization for Economic Cooperation and Development clearly put forward the "knowledge-based economy", the concept of "knowledge economy" has become a global one. hot topic. One of the distinguishing features of the knowledge economy and the traditional agricultural economy and industrial economy is that the traditional economy is an economy based on the massive consumption of natural resources (such as steel and petroleum), while the knowledge economy is mainly based on high technology (eg, software, Genetic engineering is the pillar of the industry and an economy based mainly on intellectual resources. Relevant data show that the contribution of scientific knowledge to economic growth at the beginning of the 20th century was 5% to 20%, and 70% to 80% from the 1970s to the 1990s. With the opening of the global information superhighway, the contribution of scientific and technological knowledge to economic growth The rate will reach more than 90%. It can be said that "knowledge is wealth."
In the era of knowledge economy, knowledge will become a new comprehensive soft product industry group. This industrial group mainly includes: microelectronics industry, information service communication industry, mass communication industry, library and information industry. In essence, printing technology is the technology for copying visual information. It belongs to the information industry and is a sensitive industrial sector in the information industry revolution. An electronic, digital, and networked printing technology revolution is on the rise, especially with the rapid development of digital printing, which will cause unprecedented changes in the printing industry. Looking at the history of printing technology, the arrival of the knowledge economy will surely lead to a new leap in the printing technology revolution.
During the period of agricultural economic revolution, China invented papermaking and printing—bamboo type printing technology. Although it was manual and original, it made it possible to transmit graphic and textual information. It was the first leap in printing technology. Industrial economy is the economy of machine production. The significant symbol of industrial civilization in the development of printing technology is the invention of a circular press. This industrial civilization is used in the transformation of printing presses to make printing faster and of higher quality. This is the second leap in printing technology. Similarly, with the rise of the knowledge economy, fundamental changes have taken place in the printing technology and the third leap is being made. The signs are electronic, digital, and networked.
In particular, the application of computers brought about a revolution in printing technology. This revolution involved all aspects of printing technology: the application of computers to prepress systems led to a revolution in text and image processing technologies. From color electronic color separation system to desktop plate making system, traditional plate making to direct plate processing system, prepress technology processing from analog technology to digital technology, from closed to open, it not only improves the quality of color plate making, but also greatly The shortening of the plate-making cycle has created favorable conditions for the standardization, standardization, and automation of color plates. From then on, the printing technology bid farewell to the machine civilization and become knowledgeable, electronic, digital, and open. The use of computers in printing systems has led to the maturity of printing technology. Although the main body of the printing press is still copying the printed matter by the roller rolling drive, the printing press has transplanted the computer's automatic control technology and intelligent technology onto itself, making the quality control, registration device, and ink automatic adjustment mechanism of the printing press. New improvements have been made to the atomization process and pressure control devices of dampening devices. The knowledge of printing technology has also led to a continuous revolution in printing methods. Non-contact printing and direct printing technologies have given new meaning to printing technology.
Second, the status quo and development trend of printing technology Contemporary printing technology incorporates disciplines such as mechanics, materials science, optics, computer science, and traditional printing technologies, and modern prepress technology, supported by computer technology, is becoming more and more mature. The rich development is mainly reflected in the following aspects:
(I) Application of Computer and Network Technology in Prepress Technology The main features of contemporary printing technology are digital and network. Digitization consists of image, text sampling, color separation, page processing and composition, proofing, and output to a variety of carriers (including film, media, paper, optical discs, or networks). It is entirely digital information processing and transmission. Data can be modified and stored at any stage or process in the digital workflow. This all-digital workflow will gradually replace the traditional analog processing method of the prepress process, and at the same time create the conditions for a new production process without film or plate material. In particular, with the development of the fourth media, the Internet, the use of remote network publishing and online printing as a new means of information dissemination has accelerated the once again leaping revolution in the printing industry.
Digital, networked new technologies can be summarized as:
1, Color Desktop Publishing (Color DTP) technology: It mainly uses color scanners to scan and input color images, and then separates colors, saves them into computers, and edits images and texts together on a computer. Finally, it comes from The output control system records full-page information on the film.
2, Digital proofing technology (Computer to proof): refers to the computer to play the color of large samples directly, and supporting the use of direct plate-making technology.
3, computer to plate technology (Computer to plate) is mainly the use of computer direct output of graphic information to the printing plate.
4. Computer to plate on press: It mainly uses the computer to output the information of the printed graphic layout directly to the plate of the printing press.
5, the digital printing technology (Computer to Print): Mainly refers to the computer will be in accordance with the file format digital version of the graphic text information input to the printing press printing, does not require plate making.
6, Computer to CD publishing technology (Computer to CD): It is mainly used to produce multimedia electronic publications such as optical discs.
7. Computer to Internet: It mainly uses network technology to publish electronic versions of newspapers, periodicals, books, materials and other graphic and image information on the Internet.
Digital, networked development and application have brought about changes to the traditional analog printing process and production management.
(II) Digitalization of the printing business Networking The printing, publishing and distribution of the future will be carried out through digital networking. Customers, manufacturers and suppliers will be directly linked through the Internet. The network system will enable all parties to work in coordination with each other, and will divide the business, workflow and information throughout the printing and publishing cycle.
In relation to printing business, due to the arrival of the era of knowledge economy with digitalization and networking as the main technical features, the printing industry will change the traditional way of approaching businesses, mainly: (To be continued)
