Emerald Technology Ventures' latest fund, Emerald Industrial Innovation Fund, has signed on printing ink manufacturer DIC Corporation as a limited partner.

Printing ink producer DIC Corporation has committed an undisclosed sum to the fourth fund being raised by Switzerland-based venture capital firm Emerald Technology Ventures, the Emerald Industrial Innovation Fund (EIIF).

EIIF, like its Emerald Cleantech Fund III predecessor fund, will target investments in early and growth-stage companies developing energy, water, advanced materials and industrial IT technology.

Emerald launched the fund in May 2016 with a contribution from Caterpillar Ventures, the corporate venture capital subsidiary of construction equipment manufacturer Caterpillar.
