Digitalization, Networking for the Printing Industry (China)

2. Digital network connection with printing (machine) shop. Due to the development of digital networks, the direct consequence is that it almost breaks the constraints of time and space and the earth becomes a global village. Customers connect with the press shop through a technology network.
3. Magnetic media form. Customers mainly submit live jobs to printing companies through disk and tape media to avoid problems such as proofreading and format processing, shortening the printing cycle.
Third, "print on demand" is the mainstream of this century
On-demand printing is based on the needs of users, the digital color printer directly accepts the graphic and image information provided by the pre-press system, and randomly modified graphic and image digital information to form the required graphics, images, and get personalized. Printing and printing methods still use offset printing.
The advantages of digital printing:
1. Digital printing eliminates the need for traditional printing plates, eliminates the need for film, simplifies the platemaking process, and eliminates a series of traditional printing processes such as plate orientation, ink balance, and so on.
2. The unit cost of digital print has nothing to do with the number of prints.
3. Digital products have fewer prints and shorter periods.
4. Digital printing is quick and free to change graphic and digital information, and the content of each printed product can be completed without duplication. It can be regarded as printing 1 sheet for 1 printing plate, and its quick and easy aptitude cannot be achieved by traditional printing.
5. Digital printing uses only one printing cylinder to complete the four-color printing job.
A digital color printer is characterized by the fact that only one printing cylinder and one image transfer cylinder complete the four-color printing job. Its workflow is:
(1) Electrostatic latent image Before printing, the optical conductor plate is first fixed on the printing cylinder, and the printing cylinder is scanned by a computer-controlled laser to form an electrostatic latent image on the printing plate.
(2) Electrostatic electronic ink The electronic ink of the corresponding color is then sprayed on the printing cylinder with respect to the electrostatic latent image portion of the light guide plate. At this time, the latent image portion absorbs ink, the non-graphic portion does not stick ink, and the printing cylinder is rotated. The text is transferred to the transfer roller, and then the above process is repeated for the other three color images to form a complete color image on the transfer roller.
(3) At the end of printing, the four color images are simultaneously transferred from the transfer roller to the substrate at one time to complete the print production process.
The number of digital printers is 150 or 250 dpi, and the format is 308mm x 437mm. The use of special electrostatic ink, the printing of a single color of 8,000 printing/hour, the printing of four colors of 2000 printing/hour, the printing number of about 300- 500 prints are appropriate.
From the perspective of the structure of the printing industry in the last century, publishing, printing and office printing dominated. From a worldwide perspective, printing and office publications account for 75%, and non-print publications only account for 25% of the market. With the advent of the era of social digitalization in this century, due to the development of the Internet, the demand for information has increased dramatically. The market will greatly increase both printed and non-printed publications, and on-demand printing will continue to grow. At the beginning of this century, the market share of electronic publications and online publications will reach 52%, while printed publications will drop to 48%. However, with the economic development of the printing industry, people attach importance to the packaging of products, and the packaging product printing will slightly increase its market share. Therefore, the rise of on-demand printing will inevitably produce more digital printing products. However, the printing of paper products can exist at the same time, and the two printing methods have their own advantages and disadvantages.
In the middle of this century, with digital and networked applications and developments, digital printing is an important method of information replication and dissemination. Like other information transmission methods, digital printing must inevitably be comprehensively digitized and networked.
Fourth, the printing industry has become an electronic media processing plant
We have entered the 21st century. A knowledge economy with digital and networking as the main technical features. Printing as an information media processing industry is an important way for information replication and dissemination. Therefore, management and technology must go digital and networked. The forefront of the times.
In the future, the composition of publishing and printing fields will have a multi-faceted, diversified printing and publishing process. The printing competition has also intensified, and the market share has continued to shrink. Please see the following structure to illustrate this issue.
Therefore, with the development and application of new technologies in the printing industry, we need to change the simple printing and only accept the analog printing of traditional manuscripts. To develop in the direction of electronic publishing (media processing), the company will have the competitive power of “you don't have me, you are weak and strong”. Accelerate technological transformation and promote cooperation, merger or reorganization of electronic, publishing, film and television, broadcasting, and communications industries with printing, form new media groups, complement each other, and share resources, enabling the printing industry to accept a variety of electronic documents. Electronic media processing plants that use digital information or digital information become factories that produce prints, optical discs, web pages, and online publications. Some foreign companies have implemented strong cooperation by implementing strategic cooperation and strengthening the promotion and development of digital publication. For example, Hewlett-Packard is optimistic about color digital printing in cooperation with Indigo, which manufactures digital presses; Xerox, which produces office equipment, is interested in buying Israel's Sailing Angels, which produces digital presses. To prepare for the printing industry's multimedia processing factory, to make the traditional printing-media-oriented publishing industry develop towards multimedia processing. Conversely, in this century, the printing industry that cannot accept digital information will likely be phased out or reduce production. Business source.
In terms of multimedia processing, it mainly relies on the electronic document PDF as the media. At home and abroad, the current PDF file format is the link between print publishing, office publishing, and electronic publishing. With the further development and application of printing and publishing, office publishing and electronic publishing, in the future, the electronic document format PDF that will be uniformly used at home and abroad is a new data format and electronic digital language, and is also a standard electronic information widely used in printing. format. The application of PDF documents can not only transmit and print electronic documents at home and abroad, but also can be remotely transmitted and printed via E-mail or the Internet (more commonly used abroad). In addition, it can also be displayed or printed out on the computer display through the relevant reader. (To be continued)
