- TOKYO, Japan, April 15, 2025 -

Seiko Epson Corporation (TSE: 6724, "Epson") and Epson X Investment Corporation have recently invested in Gosan Tech Co., Ltd. through a joint fund, the EP-GB L.P. Gosan Tech is a South Korean startup with inkjet technology that can be used in a variety of industrial fields.

Founded in 2015, Gosan Tech has developed and sells inkjet systems for fabricating organic light-emitting diode (OLED) displays. Through its work in this field, it has developed an ink supply system, pressure control technology, and simulation technology that enable it to achieve excellent ink droplet uniformity and precision. Gosan Tech is expanding its business in three areas: information technology, including OLED display fabrication and direct parts marking; the environment, with inkjet systems for perovskite solar cells; and bio-medical, including drug deposition, tissue engineering, and diagnostic.

Perovskite solar cells are attracting attention as a next-generation renewable energy source and candidate to replace today’s silicon-based solar cells. They are lightweight, thin, and flexible, and the cost of fabricating them can potentially be reduced by utilizing production technologies such as inkjet printing. Moreover, significant improvements in power generation efficiency have been made in recent years thanks to active research and development. Gosan Tech develops and markets perovskite solar cell modules and inkjet systems for their fabrication. These systems use inkjet technology to improve power generation, design, and material utilization by enabling thickness, material, and design modulation as well as thin-film quality.

As a partner, Epson will supply Gosan Tech with reliable and precise printheads suitable for industrial applications and will support Gosan Tech's business growth in cooperation with its sales and service site, Epson Korea Co. Ltd.

In the Epson 25 Renewed corporate vision, Epson has outlined its strategy for increasing productivity and advancing the frontiers of industry through various solutions using inkjet technology. Inkjet technology has the potential to dramatically reduce environmental impacts and realize a sustainable society.

This investment is aimed at expanding Epson's inkjet technology into diverse applications in areas where new needs are emerging, such as electronics, biotechnology, and perovskite solar cells. Synergies will be created by combining Epson’s strengths with the strengths of Gosan Tech, a company with innovative ideas and groundbreaking technology, to maximize the capabilities of Epson’s technology. Ultimately, the goal is to advance the frontiers of industry and achieve a sustainable society.

In its printhead sales business, Epson seeks to create new markets with partners. Toward this end, it is forming partnerships to enhance printhead sales and provision of solutions that include peripheral technology. By doing so, it aims to accelerate efforts to expand the ecosystem of inkjet technology applications not only in perovskite solar cells but also in new markets that will contribute to advancing the frontiers of industry and reducing environmental impact.

Going forward, Epson will help to achieve a sustainable society through co-creation with a variety of partners based on its proprietary technologies, products, and services.

Epson X Investment Corporation is a Corporate Venture Capital (CVC) firm. It is wholly owned by Seiko Epson Corporation, an information equipment and precision products manufacturer. Epson joined forces with general partner Global Brain Corporation, an independent venture capital company with expertise in managing venture investment funds, to form a fund (the EP-GB L.P.) and invests in startup companies that are expected to generate synergies with the Seiko Epson Group.
