The hottest inkjet printing technology is challeng

  • Detail

Inkjet printing technology is challenging mainstream technology (I)

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 increased the productivity of printing plants, but it has not expanded the application scope of printing as digital printing technology, and it is not suitable for personalized or short edition 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, not to 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 truepress jet520 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 truepress jet520 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 real digital 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 jet7pro printer at the IPEX exhibition last year, injecting fresh blood into the stereotyped inkjet printer market. In essence, jet7pro is a sheet fed printer, but its inking mechanism has been replaced by Epson's inkjet print head. Jet7 Quattro 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 jett7 qua pressurizing device 1 with four engines generally adopts hydraulic or pneumatic pressurization. The ttro printer 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 design of print head - put the sample platform 3. 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 360. It provides the industry in China, Asia, the Middle East and Africa with the widest range of new technology and new product reports, technology transfer, practical solutions and procurement information DPI, 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 platform 3 print head was produced by Canadian pat technology company, which launched a series of digital coating machines at the end of last year
