Sheet fed offset printing: being attacked from the back and the back

as more and more commercial printing plants can provide customers with offset printing and digital printing services at the same time, and can select appropriate printing technologies for live parts before they start printing, people have to admit that digital and offset printing technologies are equal in the field of four-color printing

however, many digital printing machines still have certain advantages in providing online post press processing function and printing products using a variety of substrates in one paper feeding process. When the printing quality is no longer an obstacle, the printing quantity and operating cost have become an important basis for people to choose between digital printing and offset printing

this can effectively solve the problem. Speed and cost determine the 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 to use digital printing, because offset printer suppliers and digital printer suppliers give different answers

Heidelberg company claims that its xuba 52 Anicolor printer is very suitable for ultra short edition printing, and sets the critical point of offset printing and digital printing at 250 (all live parts with a printing number higher than this can be printed with xuba 52 Anicolor printer)

HP indigo claims that its new indigo 7000 digital printer will be twice as high as indigo 5500 printer, and its operating cost will be lower. When printing 8-page pamphlets, the critical points of B3 offset printer and B2 offset printer are 1800 and 990, respectively. That is to say, all living parts with less than this number of prints are suitable for printing with indigo 7000

however, 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 to select printing technologies for different types and different quantities of printing materials. The printing plant can input the characteristics and costs of different printing presses into these programs, and make the correct choice between digital printing press and offset press according to the results

the new Saikang 8000 printing machine is the most promising one to change the critical point between digital printing and offset printing. Its quality level has comprehensively exceeded the current Saikang 6000, and the printing speed has been increased by nearly 50%, reaching 230 pages/minute. It is understood that Saikang 8000 is the fastest digital color printing machine in the market that should first cut off the power supply and have offset printing quality

new digital printers change the way of doing business

among the new digital printers, the most active one may be the continuous color printer. Since most continuous color printing machines target personalized transactional documents and direct mail printing market, 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 Kodak stream concept printing machine. Although it is only a concept model, the following standards introduced by Kodak company require you to carefully understand the 1 production continuous color printing machine. Its printing width is 50 cm (20 inches) and will be officially put into the market in 2010. From the samples that have been produced, this printer not only has the printing quality comparable to any high-quality digital printer in the market, but also can bring users faster speed and lower operating cost. Kodak also said that it would launch a stream printer with a printing width of 30 inches in 2013

another product is HP inkjet web press new web inkjet color printing machine. This product has the fastest printing speed (2600 pages/min), the widest printing format (76cm) and the lowest running cost

although the cost of this color printer (the cost of each A4 color page is less than US $0.01) will not be revealed until the device is officially launched in the second quarter of next year, from the analysis of the relevant data of this device, this is an improved printer and the first digital printer that can truly change the printing market. It enables publishing houses to rethink their way of doing business and produce live parts in batches. This way of printing according to customer needs can minimize the risk of publishing houses and save them a lot of production and storage costs

in addition, this printing machine can change the production mode of newspapers to a certain extent. Previously, newspapers could only be printed on uncoated paper, but now HP has begun to study the solution of printing high-quality newspapers on coated paper

in the field of offset printing, Gauss international will soon launch the M-600 web printer equipped with Vits paper cutting device, and this printer will print on coated paper with standard sheet fed ink without using a dryer. The productivity of Gauss's new M-600 printing machine can reach two or three times that of the ordinary single sheet double-sided paper offset printing machine: the machine for building the petrochemical free trade pilot zone in western Guangdong and the national petrochemical base, but the cost and operating requirements are the same as the former

it can be seen that in the future, sheet fed offset printing will be strongly impacted by low-end digital printing and high-end web offset printing
