FREMONT, CALIFORNIA— Jeff Jacobson has become executive chairman of EFI after the private equity firm Siris Capital finalised its purchase  of EFI. Jacobson resigned from Xerox in May of last year after a bitter fight  with activist investor  Carl Icahn, who battled to block the takeover of Xerox by Fujifilm. Ultimately  Icahn won, and Jacobson stepped down as CEO of Xerox. Prior to  Xerox Jacobson was CEO of Presstek, and before that he ran Kodak’s Graphic Communications Group and was CEO of Kodak Polychrome Graphics and spent time working in Canada. With his new position at EFI Jacobson added: “EFI's portfolio of best-in-class solutions presents an exciting opportunity to drive further growth in high-quality inkjet and integrated, digital workflows.
