How far is digital printing from us

in recent years, China's printing market is undergoing such changes: in the field of book printing, the number of copies of books is less and less, and the circulation of book sales hotspots is faster and faster, which requires that the cycle of book printing must also be shortened, so the publishing industry is increasingly using digital printing machines to achieve pod (printing on demand); Digital printing, which can realize personalized and variable data printing, is striding into the fields that require personalized ticket and card printing, such as telecommunications, postal services, traffic fatigue life, which is defined as the number of load cycles when old-age damage occurs, banking, securities and insurance; With the accession to the WTO and the increasing attention to the protection of intellectual property rights, the anti-counterfeiting digital printing that needs to adopt the variable two-dimensional bar code technology to meet the measurement requirements of different experimental loads is widely accepted; The proportion of short edition printing, personalized printing and variable data printing in commercial printing is also increasing, such as the printing of restaurant recipes, exhibition samples, color business cards, graduation certificates, etc., and the demand for digital printing equipment is also growing

however, digital printing is being integrated into our work and life. So what is digital printing and what are the characteristics of digital printing

definition and equipment classification

from the perspective of definition, digital printing should have the following typical characteristics: first, the printing process is the process from computer to paper or printed matter, that is, the process of directly converting digital documents/pages into printed matter; Second, the final image formation process must be digital, without any analog process or implant intervention; Third, print information is 100% variable information. That is, the two adjacent printed matter can be completely different, and even the substrate of different materials can be selected. If it is a publication, the binding method can also be different

as the core equipment of the digital printing system, the digital printing machine can be divided into two types according to the machine structure: the version free digital printing machine and the version digital printing machine. From the perspective of printing mode, it can be divided into different models for each moving picture and text and the same models for each moving picture and text, such as Heidelberg speedpa Di in Germany. Most of the latter models need to complete plate making on the printing machine, and because the printing plate is still used, there are still limitations in variable data printing

Of course, digital printing machines can also be divided into black-and-white digital printing machines and color digital printing machines. Nipson of France and Ossi of the Netherlands are strong competitors in the black-and-white digital printing machine market, while HP and Fuji Xerox occupy a decisive position in the field of color digital printing. There are three types of color digital printing machines: the first is the di type digital printing machine launched by Heidelberg company a few years ago; The second is the digital printing machine without printing plate and completely suitable for variable data printing launched by Xeikon company in Belgium and the former Xerox company in the United States. Because this kind of digital printing machine uses solid toner rather than liquid ink, it is difficult for many people to see the difference between this kind of digital printing machine and digital proofing; The third is HP indigo, which is produced by HP. Such a digital printing machine, which does not need a printing plate and uses electronic ink, can completely realize variable data printing

system composition and process

digital printing system is not much different from traditional printing system in basic composition, but as an all digital production system, it has its own characteristics:

digital printing integrates prepress, printing and post printing. From the perspective of system control, it is a seamless all digital system. The digital printing system is like a "combine harvester". The entrance of the system (i.e. the information input end) is digital information, which comes from many sources, including digital files transmitted through the network, information transmitted by the prepress system, and data contained in other digital media such as optical discs, optical disks, hard disks, etc; The export of the system (i.e. information output end) is a variety of information products with required forms, such as books, magazines, commercial publications, trademarks, cards and even packaging printed materials. Digital printing has on-demand production capacity, that is, all operations and functions can be preset according to needs, and then automatically completed by the system, so as to produce the information products required by customers

in the digital printing system, the digital printer is actually a high-speed hard copy conversion system, which is responsible for the high-speed conversion of digital pages into high-quality color hard copies, that is, printed matter. In addition, the system has high requirements for Rip: because digital printing processes 100% variable information, the output resolution is also improving, which requires rip to have a high data conversion speed

traditional printing production should go through several links, such as pre press, printing, post press and storage and transportation in the sales process, and these links should be in strict chronological order. Digital printing is not. It is a new production mode based on "digital process + digital media/high-density storage + network transmission", which can "Customize" all links of production in time according to the needs of users - if traditional printing is "production before sales", then digital printing is "sales before production"

"printing on demand/publishing on demand" is to print and produce the printed matter/publication required by customers at the time and place required by customers, but the fatigue experimental machine is just the opposite. Digital printing using this "on demand" mode is becoming more and more popular abroad, and there is also a huge and potential market demand in China. I believe that digital printing will approach us faster and faster
