EFI said that it would use the technology to enhance its customers' inkjet production capabilities for thermoforming and other high-elongation applications and to expand into new markets.
"This acquisition continues EFI's momentum in inkjet graphics printing following a highly successful SGIA Expo highlighting our leading portfolio of UV and LED inkjet technologies," said Stephen Emery, vice president of EFI's ink business.
"The technology we are acquiring will allow EFI to continue expanding our efficient, high-quality inkjet platforms into new markets."
Polymeric Imaging founder and owner Don Sloan said: "As a world leader in UV inkjet manufacturing, EFI has long set a standard for excellence and innovation in digital printing.
"This deal provides significantly greater scale and reach for the development and commercialisation of some of the key R&D breakthroughs we have made with inkjet ink."
Financial terms of the acquisition were not disclosed but EFI said it would not have any material impact on its Q4 or FY 2014 financial results.
