The Osaka Printing Inkmfg.Co., Ltd.

The Osaka Printing Inkmfg.Co., Ltd. (now operating under the name OPI Corporation, or ＯＰＩ株式会社) is a Japanese manufacturer of printing inks and related chemical products, headquartered in Osaka. The company traces its origins to 1895, when it was founded as a printing ink maker, and describes itself as having grown alongside the development of Japan's printing industry. Its core business is the manufacture and sale of printing inks and related chemical products, together with the sale of printing machinery, materials, and pigments. The company's product range covers the major printing processes: gravure inks for plastic film, flexographic inks for cardboard and roll paper, offset inks for sheet-fed paper, and screen printing inks, as well as environmentally friendly ink types and functional coating agents and colorants. It also supplies related pressroom equipment and materials. OPI positions itself as an "ink solution company" that uses color and material technology to serve diverse packaging needs, from food and sundry goods packaging to hygiene products. OPI emphasizes three core competencies: stirring technology, dispersion technology, and formulation technology. It states that it achieved Japan's first practical production of fine hologram pigments through its proprietary dispersion technology, and that it has established a system for manufacturing the required colors and physical properties in small-lot, multi-product runs. The company also offers custom development of special inks and has expanded into functional coating agents. Operationally, OPI maintains its Osaka head office along with seven branch offices and sales offices across Japan and three factories. Research and technical departments attached to two domestic factories carry out development of special inks and new products including gravure, flexographic, and screen inks and coating agents. The company also pursues environmental initiatives under the theme of "protection of the global environment and safety and health for people," developing inks that it says do not adversely affect human health or pollute the environment. As of the available evidence, the company is active and continues to announce news items and trade fair participation, including a planned relocation of its Tokyo branch office and participation in a composite materials and carbon fair. Detailed financial, ownership, and leadership information is not provided in the available sources.

The Osaka Printing Inkmfg.Co., Ltd. was founded in 1895, according to the company's own history page, which states that since its founding it has walked alongside the development of Japan's printing industry. The company was established in Osaka and built its business around the manufacture and sale of printing inks and related chemical products, later adding the sale of printing machinery, materials, and pigments. Over the decades, the company expanded its product line to cover the principal printing processes used in Japanese industry. It developed and manufactured gravure inks for plastic film, flexographic inks for cardboard and roll paper, offset inks for sheet-fed paper, and screen printing inks, serving packaging applications ranging from food and sundry goods to hygiene products. Alongside these, it added environmentally friendly ink types and functional coating agents and colorants, as well as related pressroom supplies and equipment. A notable technical achievement cited by the company is the practical production of fine hologram pigments, which it describes as the first such production in Japan, enabled by its proprietary dispersion technology. The company also highlights long-cultivated stirring technology and a formulation system that allows small-lot, multi-product manufacturing of required colors and physical properties, supporting custom development of special inks. To serve customers across Japan, OPI established a network of offices and plants. Its Osaka head office is complemented by seven branch offices and sales offices nationwide and three factories. Research and technical departments attached to two domestic factories conduct development of special inks and new products including gravure, flexographic, and screen inks and coating agents. At some point the company adopted the operating name OPI Corporation (ＯＰＩ株式会社), while retaining reference to its former name, Osaka Printing Ink Manufacturing Co., Ltd. The company continues to operate actively, announcing news such as the relocation of its Tokyo branch office of the East Japan Sales Department and participation in the Composite Materials & Carbon Fair 2026. It also maintains environmental initiatives centered on the theme of protecting the global environment and ensuring safety and health for people, developing inks intended not to harm human health or pollute the environment.
