As more and more commercial printing plants can provide offset and digital printing services to customers at the same time, and can choose the right printing technology for the job before printing, people have to admit that digital and offset printing technology in the four-color printing field Evenly matched.
Nonetheless, many digital printers still have a share in terms of providing online post-press processing functions and printing products that use multiple substrates in a single paper pass.
Certain advantages. When printing quality is no longer an obstacle, the number of prints and operating costs have become an important basis for people to choose digital printing and offset printing.
Speed ​​and cost
Decide on printing method
It is difficult to answer the question of how much operating cost and printing quantity is more cost-effective to use offset printing than digital printing, because offset press suppliers and digital press suppliers give very different answers.
Heidelberg claims that its Speedmaster 52Anicolor printing machine is very suitable for ultra-short version printing, and sets the critical point of offset printing and digital printing at 250 prints (all jobs higher than this number of prints can be printed with Speedmaster 52Anicolor Machine to print).
HP Indigo claims that its new Indigo7000 digital printing press will be twice that of the Indigo5500 printing press, and its operating costs are also lower. It is critical to B3 and B2 offset presses when printing 8-page brochures. The points are 1800 and 990, respectively, which means that all jobs below this number are suitable for printing with Indigo7000.
But companies like Xerox can also provide customers with reference data based on the number of prints. These digital enterprises generally have a set of software programs that select printing technologies for different types and different numbers of printing jobs. The printing house can input the characteristics and costs of different printing presses into these programs, and make the right choices in digital printing presses and offset presses based on the results obtained.
The new Xeikon 8000 press is the most promising one to change the critical point between digital printing and offset printing. Its quality level has fully exceeded the current Xeikon 6000, and the printing speed has been increased by nearly 50%, reaching 230 pages / minute. It is understood that Xeikon 8000 is the fastest digital color printer with offset printing quality on the market today.
New digital printer
Change the way you do business
Among the new digital printing presses, the most active one is probably the continuous color printing press. Since most continuous color printing presses target the personalized transactional documents and direct mail printing markets, they will not have much impact on the transition from offset printing to digital printing.
There are two products that may change the future of offset printing and digital printing. The first is the Kodak Stream concept printing press. Although it is only a conceptual model, the first continuous color printer produced by Kodak has a print width of 50 cm (20 inches) and will be Officially put on the market in 2010. Judging from the samples that have been produced, this printing press not only has the print quality comparable to any high-quality digital printing press on the market today, but also can bring users faster speed and lower operating costs. Kodak also said it will launch a Stream printer with a 30-inch printing width in 2013.
Another product is the HP InkjetWebPress new web inkjet color printer.
This product has the fastest printing speed (2600 pages / minute), the widest printing format (76 cm) and the lowest running cost.
Although the cost of this color printing machine (the cost of each A4 color page is less than $ 0.01) will not be announced until the device is officially launched in the second quarter of next year, but from the relevant data analysis of this device, this is a The improved printing press is also the first digital printing press that can truly change the printing market. It allows publishers to rethink the way they do business and batch-produce jobs. This way of printing according to customer needs can minimize the risks of publishers and save them a lot of production and storage costs.
In addition, this printing press can also change the way newspapers are produced to a certain extent. Previously, newspapers could only be printed on uncoated paper, but now, HP has begun to research solutions for printing high-quality newspapers on coated paper.
In the field of offset printing, Gauss International is about to launch the M-600 web printing machine equipped with a VITS paper cutting device, and this printing machine can coat paper with standard sheet paper ink without using a dryer. For printing. The productivity of the new M-600 press from Gauss can reach twice or three times that of ordinary sheet-fed offset presses, but the cost and operating requirements are no different from the former.
This shows that in the days to come, sheet-fed offset printing will be strongly impacted by low-end digital printing and high-end web offset printing.
