First, digital printing overview
With the rapid development of digital technology and the increasing demand for personalization, digital printing technology has become a major trend in printing development. Digital printing enables variable data printing, personalized printing, on-demand printing and web printing for areas where traditional printing is not available. Digital printing provides customers with a new all-round service with its personalized, fast and flexible features and advantages.
What is digital printing?
Digital printing is a new type of technology that uses prepress systems to transfer graphic and text information directly through data lines or networks to digital printing machines to print various finished products. Digital printing has the characteristics of flexible printing, diversified and personalized printing, convenient storage and re-callable electronic printing. Digital printing can provide users with targeted and personalized printing services according to users' time requirements, location requirements, quantity requirements and certain specific requirements.
Typical characteristics of digital printing:
1. The digital printing process is the process of printing information directly from a computer onto a substrate. It does not require film and printing plates to directly convert digital files/pages into printed matter.
2. Achieve 100% variable information printing, that is, two prints can be completely different, including layout, content, size, and even different materials of the substrate and binding method.
3. Can be printed off-site. The same electronic file can be sent over the Internet to multiple clients using digital presses for remote printing.
4. Can be printed on demand. In addition to the ability to change content as desired, the number of prints is not limited, even for single-printing, digital printing can be easily achieved.
Advantages of digital printing:
1. Short cycle. Digital printing eliminates pre-press processes such as film, plate making, and proofing, simplifying and shortening the process and time.
2. Production is fast and flexible, and can be modified at the last minute before printing.
3. It is convenient for digital connection with customers and provides networked services.
4. Easy to provide a personalized service plan.
Two. Digital printing market prospects
After the digital printing technology was exhibited at the Drupa 1995, it caused great repercussions around the world. New business areas such as variable data printing, personalized printing and on-demand printing are constantly breaking through and impacting the traditional printing market. In the United States, the annual growth rate of digital printing retail sales is about 18%, Europe is about 22%, and the rest of the world is about 8%, which is higher than the overall average growth rate of the printing industry by 3% to 4%.
According to the US NPES forecast, by 2011, the global printing industry will reach 721 billion US dollars, the output value of digital printing will reach 154 billion US dollars, accounting for 21.4%. At least 20% of users require less than 24 hours of delivery, while 78% of color printing jobs currently have fewer than 5,000 copies.
The facts show that the growth of most digital printing in Europe and the United States comes from the shrinking of the traditional printing press market, and traditional printers have also realized the importance of digital printing. In a survey conducted by the National Printing Guidance Association (NAPL), 48% of the answers to the question "Which service plan do you plan to increase in the next two years" are "digital printing services", far more than "electronics" The answer to Business and Database Management. Digital printing has become the first choice for European and American printing companies to seek value-added personalized and professional printing services.
In China, the digital printing market is also developing rapidly as China's economy continues to grow steadily. According to the China Institute of Printing Technology, Keyin Media's "2009 Digital Printing in China" survey report, from June 2007 to July 2009, the total installed capacity of high-end color digital printing presses and various types of production digital printing presses in mainland China The volume has increased from 565 to 1,410 units, with an annual increase of more than 400 units. Among the companies surveyed, 52.27% said they would consider investing in digital printing equipment again.
The development of digital printing at home and abroad has shown the fact that digital printing has become an inevitable choice for the traditional printing industry to integrate into the modern information trend.
Three. The future development of digital printing technology
The current digital printing technology can be divided into three categories according to the imaging principle:
1. Electrophotographic (Electro photographic), also known as Xerography technology;
2. Ink-jet printing system;
3. Others: Electron imaging technology (Elcography), magnetic particle imaging technology (Magnetograph), electron beam imaging technology (Electron-Beam Imaging), magnetic powder inkjet technology (Toner Jet).
Among them, inkjet printing has become the main force of the digital printing industry due to the rapid development of the nozzle technology, the continuous improvement of the printing speed, the continuous improvement of the printing quality and precision, and the wide adaptability of materials. At present, there are two mainstream development directions for digital inkjet printing:
1. High-speed inkjet digital printing High-speed inkjet digital printing has attracted much attention in the industry because of its comparable traditional printing volume and its digitally variable characteristics. In high-speed inkjet digital printing systems, the mechanical and nozzle parts are no longer difficult to use. Whether to support high-speed RI P systems for high-speed inkjet digital systems, and digital process systems under high-speed RI P, and related high-speed automatic typesetting software, will become the key to the full performance of the entire system. Therefore, companies with RI P technology, process technology and typesetting software technology will have a greater advantage in the competition.
At present, several suppliers around the world that mainly provide prepress solutions have been involved in high-speed inkjet digital printing. Kodak Wanyin introduced V-series and D-series high-speed inkjet printing systems; Agfa and Thieme collaborated to develop the M-Press system; Japan Screen's TruePress Jet 520 system (see photo), which has been continuously developed and improved, Stability, quality finesse, production performance and cost; Agfa launched the Dotrix series for the packaging market.
2. Large format inkjet printing
Large format inkjet printing products are generally divided into two categories: one is a wide-format 24-74-inch large-format inkjet printing products, such as Epson, Canon, Hewlett-Packard, Roland and other imported brands are such models, the accuracy High (above 1200dpi), slower speed, low investment, high production cost, suitable for indoor applications or outdoor small format advertising production. The other type is a large-format inkjet printing device with a width of more than 74 inches (3 meters, 5 meters, or even 7 meters), that is, large-format inkjet printers, such as EFI Wit, Hewlett-Packard Angel, and domestic Yaslan. It belongs to this type of machine and has large format and high efficiency, but its precision is relatively low, the investment is large, but the production cost is low. It is suitable for the production of large outdoor billboards.
Large-format inkjet printing has been a great success at Drupa 2004. With the active development of major suppliers, the speed of large-format digital printing has increased by more than 20 times in just 5 years, and the cost has been greatly reduced. 90%. Large format inkjet printing with large printing format, continuous printing performance without length limitation, and variety of printing materials, in engineering design, graphic image, outdoor advertising, photo, exhibition, decoration, art reproduction And digital proofing and other fields have been widely used. The huge market for large format inkjet printing and the broad development prospects have attracted a large number of domestic and foreign manufacturers to invest in it. For example, the True Press Jet 2500UV (pictured) launched by Drupa 2008 in Japan is the focus of high-quality, high-speed and flexible settings of 5 different resolutions of 300-1500dpi. Since then, the screen has introduced a 1.6-meter wide format inkjet device True Press Jet 1600U V to meet the market demand for mainstream printing in the field of inkjet printing.
In addition to the performance of the device itself, powerful workflow and data processing functions, as well as technical performance indicators such as computer hardware and network equipment, will affect the effect of large-format inkjet printing equipment. Therefore, a comprehensive solution that includes processes, networks, software, hardware, and services can truly eliminate the worries of users.
