Our 3D Cell Culture Technology is a technique that enables the pseudo-formation of micro-parts of the human body by co-culturing multiple cells in three dimensions using a proprietary method. This technology has potential applications in a wide range of fields, including drug efficacy and toxicity testing in drug discovery research, personalized medicine, cultured foods, and regenerative medicine. Going forward, TOPPAN aims to accelerate technology development through collaboration with various research institutions and create new cell-culture-related products and services.

As treatment techniques for diseases diversify, innovation is required in specimen analysis techniques to determine increasingly complex treatment plans. TOPPAN is developing a diagnostic platform to facilitate advanced medical care. This technological development applies the microfabrication, fluid simulation, and test reagent development technologies we have cultivated thus far.

As part of our efforts to contribute to carbon neutrality, TOPPAN is conducting research and development of catalyst coated membranes (CCMs) and membrane electrode assemblies (MEAs). TOPPAN’s CCMs and MEAs can be applied to water electrolysis devices that produce hydrogen, electrolytic cells involved in hydrogen storage and transportation, and fuel cells that use hydrogen. We can develop the ideal MEA for each customer through our precision coating and structural design technology.

In a world seeking carbon neutrality, TOPPAN will create a sustainable energy technology that will open the way to the future by manufacturing bioethanol from waste paper. This innovative process, which can be used for aviation fuel and other purposes, reuses difficult-to-recycle waste paper, such as water-resistant paper and foil-stamped paper, achieving reductions in waste and CO2 emissions. TOPPAN will stay on TOP of its mission to create clean energy from underutilized resources.

At TOPPAN, we are dedicated to creating a secure and rapid communications environment for the 5G/6G era by providing electromagnetic wave control solutions. We are developing materials that enable ultra-high speed, ultra-low latency, and multiple simultaneous connections by selectively absorbing multiple radio waves to reduce interference and leakage from wireless communications devices, as well as designing spaces utilizing the materials.

CMS stands for Color Management System. At TOPPAN, we apply our CMS technology, cultivated as part of our quality control for print materials, to the IT domain. We are also working to solve communication issues related to color on PCs and smartphones.

This research aims to harmonize color differences caused by photographing the same object with different cameras or displaying images on different monitors, enabling the recording and transmission of color information under unified conditions. Applications include reducing return rates on apparel e-commerce sites by accurately conveying the appearance of clothing, as well as facilitating appropriate treatment in telemedicine by accurately conveying the appearance of affected areas of the body.

TOPPAN’s security holograms have been uniquely developed based on electron beam technology used in semiconductor manufacturing. Thus far, we have provided Crystagram™, which depicts graphics with high-definition images, and Photo Color Holo™, which is as vivid as a photograph.

Developed based on TOPPAN’s proprietary coating and vapor deposition processing technologies, this eco-friendly transparent vapor-deposited film offers high barrier performance comparable to that of aluminum foil. With its high barrier performance and transparency, as well as being non-metallic, it is used in various fields including food, industrial materials, electronics, and medicine/pharmaceuticals.

This is a liquid crystal film that changes between transparent and opaque at the flick of a switch, utilizing the liquid crystal technology cultivated by our display business. This film, when applied to glass, offers various uses such as security measures, privacy protection, and usage as a screen. TOPPAN has also developed the world’s first reverse type that turns transparent when power is off, as well as a “Normal Black” grade that turns black with a visible light transmittance of 5% when not powered.
