    Ink jet technology has a wider market on account of its upgraded functions and improved performance with regard to the simple marking process. However, this trend has leveled out in the personal market, and the activity in this market has fizzled out. In this situation, two obvious directions for progress in ink jet technology exist. One is the extension of ink jet technology applications to those involving the simple marking process, and the other means challenges against performance limitation derived from imaging process achieved only by the interaction between ink and media. Differences exist between the technical approaches used for each of the above paths of technological progress. Progress in elemental technology has been noticeable in terms of the extension of the technology to other applications, and significant breakthroughs have been achieved in system integration or peripheral technology concerning the overcoming of the performance limitation.I have presented below the current status of progress in ink jet technology and the prospects corresponding to the two possible directions of progress in this technology.

    It is a recent trend that ink-jet techniques are utilized to actively advance into a new industrial field. However, ink-jet technologies have some technical limitations although we can find how to break those limitations in some cases. Anyway, it is difficult to solve the problems using only an independent technique. Combination of some technologies such as inks, media, and hardware including their comprehensive systems are important. In addition, the choice of the business domain is also necessary.

    Inkjet textile printing and IC marking devices are examples of the latest advances in industrial inkjet applications. The use of the inkjet textile printing technology is spreading in the Italian high-quality cloth market because of its ability to cater to on-demand printing requirements while providing excellent quality. For example, Monnalisa, which has specific colored inks and requires an integrated, densely-packed print head, has successfully achieved high-grade print quality even for high production rates. It will produce the expected result in markets in other nations provided users take interest in the promotion of digitalization for small-lot production. Inkjet IC marking devices have the advantage of being able to produce damage-free ICs, while printing images having good visibility and providing the on-demand printability feature. For example, IP2000 is printed on with visible white ink that is used in combination with UV and heat cure systems. This technology will evolve suitably to enable its use with small IC chips or thinned array packages in the near future. Inkjet technology is said to have a wide range of existing and potential applications in the industrial sector. As inkjet technology progresses, it appears that further progress in this technology requires simultaneous advances in the peripheral technology that enhances the overall inkjet printing system.

    Tailor-made, regenerative medicines have attracted much attention since the discovery of iPs cell technology. However, it is very difficult to reproduce a required tissue and organ from a cell in vitro. Our body consists of various cells and biological compounds, and these cells and compounds interact with each other and achieve a precise balance. In addition, they form an optimum structural design owing to the power of nature. In other words, the reproduction of a required tissue or organ can be achieved only when such an exact structure can be formed in vitro. Ink-jet technology is now attracting attention as a technique that can be used to realize the exact and most suitable placement of a cell and scaffold. Some groups study customized bone regeneration and the making of a tissue model with hydro gel. These cases point to the great potential of inkjet technology for future applications.
