The hottest inkjet technology challenges the mains

Inkjet technology challenges mainstream technology

in the past two decades, many printing houses have accepted the reality that if they want to survive, they must adopt new technology. Desktop publishing, automatic version change, CTP, JDF and other technologies have played a vital role in the survival and development of printing plants. Now, another new technology has emerged in the printing market, and it will shake the dominant position of offset printing technology

recently, the advantages of inkjet printing in the mass printing market have significantly exceeded the traditional printing process. The improvement of traditional offset printing technology, especially the reduction of printing unit price and the improvement of automation level, has greatly improved the productivity of printing plants, but it does not expand the application scope of printing like digital printing technology, and it is not suitable for personalized or short version printing

in the past two years, many large printing suppliers, such as Agfa, Fujifilm, big Japan screen, Kodak and HP, have invested a lot in the development of inkjet products

breakthrough field

the first commercially successful color inkjet printing device is the Versamark system launched by Kodak. This printer is mainly used for the printing of transactional mail, adopts high-speed continuous inkjet technology, and can print forms and bills with water-based ink through a 22.8cm wide print head. DSTi, astron and other companies are loyal users of Versamark. On average, they can print 16million pages a month with this device, with a maximum speed of 1000ppm

with the continuous growth of TransPromo business (which refers to adding color to invoices or statements), the printing market has also undergone earth shaking changes. Because the quality level of high-speed printing is relatively limited, the biggest role of color printing is to attract people's attention, rather than show the effect of color itself

in the field of high-speed color inkjet printing, Kodak and big Japan screen Co., Ltd. jointly launched the truepressjet520 printer, which integrates the prepress and workflow technology of the screen with Epson's piezoelectric on-demand inkjet print head. This web printer has a width of 52 cm, a maximum speed of 64 meters/minute or 210 pages (A4)/minute, and uses water-based pigment ink. Although the price of truepressjet520 printer is similar to that of other inkjet solutions, its printing quality is better than Kodak Versamark

for high-quality printed matter including direct mail, people prefer to let realdigital company produce it. Real company has an inkjet web printer with fixed print head, and generally uses UV curing ink for printing. In addition, their print heads are manufactured by Toshiba company authorized by Xaar

inov media, a French inkjet technology developer, launched its own JE t7pro printer connected by Internet and IOT at the IPEX exhibition last year, injecting fresh blood into the stereotyped inkjet printer market. In essence, jet7pro is a sheet fed printing machine, but its inking mechanism has been replaced by Epson's inkjet print head, and the size of die hole and door is still correct. Jet7quattro is the latest model in this series. It not only adopts the fastest Xaar print head, but also is equipped with different numbers of print heads, so it can scan the whole page and conduct bidirectional scanning with resolutions of 360 and 720dpi. Depending on the number of engines, the maximum speed this printer can achieve varies. For example, the jett7quattro printer with four engines can print up to 160 B1 pages with a resolution of 720dpi or 400 ordinary pages with a resolution of 360dpi per hour. It is understood that the jet7 series printer can generally be equipped with 2 to 20 engines

Design of print head

Saier company recently launched the latest designed print head platform3. This print head has two rows of nozzles (1000 in total), the imaging range is 70.5mm, and the maximum resolution it can support is 360dpi, so it can bring users the same quality as ordinary color printing. Cel claims that the consistency and stability of this print head have been significantly improved compared with the previous products. The first commercial version of the platform3 printhead was produced by pattechnology of Canada, which launched a series of digital coating machines at the end of last year

Saier believes that platform3 print head will promote the development of a new generation of high-end color printers. Iandinwoodie, the CEO of the company, predicts that by the end of 2008, the high-quality inkjet printer with a speed of 167ppm will be exported to developed countries, and the medium and low-end printing machine will compete with the high-speed toner printing machine, and will double its speed in the next few years. By the end of 2010, the inkjet printer with a speed of 500ppm will appear in the market, which will bring the advantages of non-contact inkjet technology into packaging and other fields

after acquiring pimatix last year, Fujifilm grandly launched its own versadrop technology. This technology can not only change the size of ink droplets, but also improve the quality of gray-scale printing. Pimatix claims that controlling the size, shape and position of ink droplets can help smooth the transition of printing tone and make the details of the image clearer. It is understood that the commercial system using this technology will meet with the majority of users later this year

although the supremacy of offset printing, gravure printing and flexographic printing will still be shaken by inkjet technology in the next five years, they will be hit hard by this technology. With the continuous emergence of new technologies, it will be more difficult for users to make choices. Some users have tasted the benefits of new technologies, such as realdigital and smpgroup. Printing houses should study hard?? Different requirements

printing customers of direct mail, packaging and point of sale advertising will benefit greatly from the progress of inkjet technology, because they can change the content on each page according to their own needs. Most printing plants are already using inkjet printers for proofing, and this technology is also very Digital: what they want is that it is not correct to call the Rockwell hardness. They can produce high-quality contract samples at the unit cost of offset printing and the speed of Versamark, and can print on a variety of substrates. This sounds like a long time, but inkjet technology can provide people with more potential solutions faster than you think

other digital printing technologies that can replace ink-jet technology

among all the technologies that can compete with offset printing, ink-jet technology occupies a dominant position. But many manufacturers are trying to develop digital technology that can replace inkjet technology

Xerox has entered the industrial inkjet printing market with its phaser system. The system can melt the wax block and spray it out to dry it on the paper

Ricoh is also looking for products that can replace inkjet inks, and has developed a gel like waterproof quick drying viscous ink, which will not cause problems such as dirt or leakage. But this ink is mainly aimed at the office environment, not the commercial printing environment

the hybrid system that integrates inkjet technology with traditional printing technology has been favored by more and more fields, especially in carton processing and packaging industry. If people want to print directly on the surface of thick hard substrate, the advantages of inkjet technology will be more obvious
