New application and development direction of industrial inkjet printing technology

this paper introduces the transforming inkjet printing industry, which has expanded from the previous household and office inkjet printing to the production of labels and bar codes, CAD drawings and large format images. Next, we will introduce the latest applications of inkjet printing one by one

scientists at the University of Manchester in the UK are developing a new technology - using an inkjet system - to print live human stem cells on injured patients, that is, doctors should transplant some alternative cells to patients, let them grow into appropriate sizes and shapes, play a corresponding role, and complete treatment. If the stem cell is obtained from the patient's own body, the probability of its rejection by the human body will be significantly reduced. Brianderby, a materials expert in Manchester, believes that the University of Manchester has successfully used this special technology to store and culture human osteoblasts and fibroblasts, which are used to form bone and muscle tissue. Derby said: "We are very interested in those cartilage, bone and vascular tissues. Skin is also an application field, but even if printing has entered this field, it is not our research focus. Our research team is working closely with Xaar, the developer of print head, to improve the technology used to transmit bone repair or cell migration, which is an important alloy element with beauty, water resistance and vanadium preservation. Temperature and heat insulation lamps have become the common requirement of every family Inkjet printing equipment for human cells such as plants. " If we hear the above story in an isolated place, it may surprise and curiosity us, but it is not a fictional story. Inkjet printing technology is breaking through the Convention and entering many magical and unfamiliar markets, such as biotechnology, bioengineering, law, metal precipitation, microstructure manufacturing, electronic manufacturing, networking, pharmaceutical, glass, ceramic decoration, display manufacturing and other fields - it is simply impossible to list them one by one

the problem is that these exciting things are very trivial and lack a scope or focus. Yes, I admit that the efforts of some research groups are very serious. For example, IMI in Geneva recently held a symposium entitled "commercialization of inkjet printing technology as a manufacturing process". Nevertheless, such seminars also have limitations, that is, they seem to form an interesting forum for exchanges between inkjet printer manufacturers, an "old boy club" in the inkjet printing industry. The purpose of the organizer of this kind of conference is to arouse the interest of new members and potential users of new enterprises in inkjet technology within a certain range and advertising budget - unless these new members and end users have realized the benefits of inkjet technology, or participate in this conference through the introduction of their digital partners

so next, I want to emphasize two things. First, what can effectively promote the development of industrialized inkjet printing technology? Second, if we have been exposed to inkjet technology in some traditional silk printing markets - or as a manufacturer, distributor or graphic and textile processor - why do we actively see the development of inkjet technology industry? I want to answer the second question first, and I want to establish contact with more readers

the importance of the industrial market

in on-demand inkjet printing, only four companies have a really large (millions) inventory of print heads: HP, Epson, Canon and Lexmark (Lexmark). This is because only these four companies have successfully sold their print heads into the office and consumer inkjet markets. By adjusting the threshold for ink-jet cartridges to enter the above market, these companies have the economic strength to invest in new print head technology and high-level manufacturing process. For example, at present, the price of a nozzle on the print head has fallen to a very low level

in terms of the performance of these manufacturers, at present, the manufacturers of three print heads are limited by the thermaldod technology, which limits their choice of water-based inkjet materials with low viscosity. As a result, these companies are excluded from most potential industrial applications and markets. Epson's print head is a piezoelectric ink-jet on demand (DoD) print head. Although it is difficult for people to obtain the sales right of Epson print head, it also has certain industrial application potential

the second problem is that the size of ink droplets ejected from all the above print heads is very small, which may also be a limitation of its industrial application. In silk printing, we need three types of eyes, large, medium and small, to print ink on the surface of the substrate according to different needs; Similarly, in the field of ink-jet printing, we also need nozzles with different diameters and different injection frequencies to meet different needs. The mass production we mentioned above cannot serve the public in the new industry at present

this also leaves market space for spectra, Xaar, Ricoh (formerly Hitachi), Konica and other industrial inkjet printer manufacturers that produce high-yield print heads. But there is also a bad aspect, that is, because these print heads are relatively not mass-produced, the manufacturer's cost is relatively high. As these industrial manufacturers have to develop a variety of different inkjet print heads to meet the needs of different markets, this problem will continue to intensify, further affecting their output and increasing their development costs. There are two final results, either the price of the print head is very high, or the manufacturer of the print head makes a profit by selling ink, so as to invest money in RD and production technology

therefore, why do printers and suppliers related to inkjet printing of graphics or texts urgently need to develop industrialized inkjet technology? Because this can ensure that the output of print head manufacturers continues to grow, so as to ensure that the prices of nozzles and printing inks continue to decline, making inkjet printers more attractive to large-scale printing production and a large range of customer base

promote the expansion of industrial inkjet technology

now we can return to the first question: "what can effectively promote the development of industrial inkjet printing technology?" This seems to contain two problems: the exchange and awakening between enterprises that benefit from industrial inkjet technology

in terms of images, we have held many trade exhibitions and conferences to attract traditional inkjet printing businesses. Of course, we don't need to do this anymore. However, the situation in the field of industrial inkjet is quite different from that of traditional inkjet. At present, there is no industrial inkjet technology exhibition that can really attract new customers, and no one can clearly know who is the target and how to find the target in such exhibitions or conferences. There are many trade exhibitions on traditional industries such as biotechnology, medicine, packaging and electronics, but few such exhibitions on industrial inkjet technology. For manufacturers of special print heads/inks/hardware, the cost for investors to open up new markets is very high, and the preparation time of ROI is also very long. In some cases, inkjet technology may compete with other technologies, and in the early stage of people's awakening, the foundation of traditional manufacturers seems to be more threatening than opportunities. We have seen this reaction in the image industry before

this also led to a heated discussion on the statement that "we need some technical use rules of Jinan new era assay instrument Co., Ltd. for materials, we have our own unique technical support, and we need a new exhibition and conference atmosphere simply about industrial inkjet technology". This requires a place where entrepreneurs, venture capitalists, inkjet technology companies, leading educational research institutions and users of innovative technology can meet, exchange views, and formulate and implement inkjet technology development plans

in my opinion, there are two trade organizations that can explain and understand these goals based on their experience in the industrial application of silk printing and gravure printing and their understanding of the inkjet printing industry - they are the specialtygraphicimagingassociation and its brother unit in Europe, fespa

the support of industrial inkjet technology requires a lot of investment, and can not guarantee anyone that it will succeed immediately. These two organizations can only assure their members that this project may be successful in the near future. In the initial stage of success, these organizations need to strengthen cooperation with the organizers of competitive digital exhibitions. As an emerging industry that has found a law, we cannot let it fail

I also want to tell those developers and manufacturers of print heads, hardware, media, ink and software that if you want to invite organizations like SGIA and fespa to help you more effectively promote industrial inkjet technology, you need to give them enough money to do this. You need to make sure that they are spending your money in the way you like, and you also need to ask senior people in this field to help you set goals and directions for them

inkjet is such a widely used industry. If we can improve the way of capital and resource allocation and invest in its new technology, it will certainly bring us opportunities for career development and long-term economic benefits. I think it's time to make this cake bigger before everyone starts competing for it
