KEYNOTE: Development of Image Recognition based on Human Perception Functions, Masashi Nishiyama, professor, Tottori University (Japan)
Abstract: Image recognition is expected to be used in various industrial applications such as security and marketing. This presentation introduces image recognition technology that extracts features by mimicking human perception functions. These functions involve quickly identifying informative image regions to obtain robust recognition accuracy. To achieve this, I reveal the gaze distributions when people understand the content in images and incorporate these distributions into the recognition algorithm. The developed recognition algorithm has the advantage of high stability because humans can intuitively interpret feature extraction.

Morphology Control of Inkjet-Printed Silver Lines, Jun-Young Hwang, principal researcher, Korea Institute of Industrial Technology (Republic of Korea)
Abstract: In printed electronics, morphological characteristics of the printed micro-patterns have a significant impact on the performance of the device. In particular, the industries of highly integrated electronics and opto-electrical energy devices demand highly fine and highly conductive electric interconnections. However, it is not easy to achieve both of these two goals in typical inkjet printings of metallic nanoparticle inks, where aspect ratios of printed patterns are very low. In this study, silver lines having higher thickness and narrower width are produced by inkjet printing with selective surface wetting techniques. (Paper authors: Jun Young Hwang, Yoon Jae Moon, Kwon Yong Shin, Jun Ho Yu, Chanwoo Yang, and Sang‑Ho Lee, Korea Institute of Industrial Technology.)
Dr. Jun Young Hwang holds a PhD in mechanical engineering from Seoul National University. His research there was on soot formation in counterflow diffusion flames of ethylene and propane. His current research interests are on laser-assisted inkjet printing for display & lighting devices.
Ricoh's binder jetting technology of aluminum alloys, Daichi Yamaguchi, technical expert, Ricoh Co., Ltd. (Japan)
Abstract: Metal binder jetting (BJT) is a low-cost, highly productive additive manufacturing method that selectively deposits binder on a powder bed to create a green body that is subsequently sintered. Despite its high demand, it has been difficult to realize BJT for aluminum due to material restrictions on the ease of sintering, because metal BJT is integrated technology with sintering. Ricoh is now realizing aluminum BJT through a highly developed sintering process and optimization of materials and the overall process. This technology can be applied to a variety of applications, including the manufacture of extremely high-performance heat exchangers and lightweight structural components that reduce environmental impact.
Dr. Daichi Yamaguchi is a technical expert in Ricoh’s development department, additive manufacturing business center. He started his career in electrophotographic technology development before transferring additive manufacturing where he is currently responsible for developing sintering technology within Ricoh binder jetting team.

Inkjet Printing Technology for Display Pixel Patterning (working title), Jun-Young Kim, Professor, Gyeongsang National University (Republic of Korea)
Abstract: Recently, the paradigm of the display is rapidly changing to a self-luminous display. A typical example of a self-luminous display is OLED, which is manufactured using a vacuum deposition process and is currently being applied to Samsung's Galaxy cell phone series and LG OLED TVs. However, the current process has disadvantages such as large area and limitations in material use. To solve these problems, the inkjet printing method, which is a soluble process, can be an alternative, and the inkjet printing process is developed by directly patterning organic or inorganic nanoparticles, which are solution-type materials, on unit pixels. This presentation deals with issues and solutions that may arise from the perspective of developing a display through an inkjet printing process. In particular, it introduces the stable ink discharge of inkjet printing materials, and uniformity issues of pixel thin films facing the display of the inkjet printing process, and presents challenging challenges to solve.
Following his PhD, Dr. Jun Young Kim conducted research on soluble OLED at LG Display, then on printed electronics in KITECH (Korea Institute of Industrial Technology). Kim is currently a professor in the Department of Semiconductor Engineering. His research interests are inkjet printed based OLED & QD-EL (next generation display) and photovoltaic device (next generation energy source).

Multi-Factor Authentication and Variable Data Printing, Steven J. Simske, professor, Colorado State University (US)
Abstract: Cyber-physical security is enhanced by advanced variable data printing (VDP) approaches that allow variable marks to be printed on branded material such as packaging, labels, and medallions. These marks, including QR codes and Data Matrix 2D barcodes, are automatically read by most mobile cameras, and can direct the mobile device to a website. A web service associated with the website to which the mark directs the consumer can be used to highlight other VDP information on the packaging or labeling that a human can validate. This combination of VDP and web service provides a two factor (package and web service) authentication in addition to allowing reinforcement of brand value by directing attention to the product packaging and directly connecting the consumer to the manufacturer website. Mechanisms through which to provide multi-factor authentication for brand development, brand protection, and brand communication are highlighted in this talk.

Explainable Design Analysis Technology and Solution, Natsuko Minegishi advanced expert, Konica Minolta, Inc. (Japan)
Abstract: In the digital printing market, not only are printing technologies, but also the solution business is attracting attention from printing business managers. Some such managers have expanded their business areas beyond printing production to include solution businesses that support marketing. However, many printing companies have employees who are not familiar with marketing and are perplexed by the sudden change in policy that run counter to one of the SDGs, “decent work and economic growth”. Konica Minolta developed the Design Analysis System based on the belief that visualizing graphic design effect would be one of the solutions to such a situation. The results of the analysis were made explainable by using not AI that is currently attracting attention, but rule-based algorithm. The main technologies of the system are an extension of image processing such as that found in printers. This talk discusses the technology offered by the Design Analysis System and its business benefits. (Authors: Natsuko Minegishi, Shoichi Uratani, Satoru Inoue, Konica Minolta, Inc.)

Ultra High Viscosity jetting for Additive Manufacturing, Ramon Borrell CTO, Quantica GmbH (Germany)
Abstract: Many materials of great interest in printing and additive fanufacturing cannot be used with conventional inkjet printheads due to physical properties such as viscosity, particle size, or surface tension being outside the range permissible for ejection. Quantica has developed a novel printhead with a new concept of piezo actuator that dramatically expands the capabilities of inkjet printing up to 400mPas at jetting conditions. The new design also allows for larger and denser solid particles and has been successful at depositing materials with surface tension above 700mN/m. Many new applications in additive manufacturing can benefit from combining a number of high performance materials that can be deposited with the versatility and scalability of inkjet printheads.
Mr. Ramon Borrell is CTO of Quantica, a 3D printing company in Berlin, Germany. He has spent most of his career in R&D for inkjet printers and printheads with HP, Xaar, and as a consultant before joining Quantica in 2021. He is currently a member of IS&T’s Board of Directors..
