The company, which has offices in the US and France, has doubled its space in the UK with the move to a larger facility at Froomsgate House, Bristol, where its 15-staff team will be based.
Sefas, which established its first office in the UK in 1999 when it bought Fraser Williams, will have a training centre at the office, where clients can learn about new and existing products.
Managing director Giles Hill said: "Froomsgate House is an excellent location for us and gives us plenty of room to expand in the future to meet growing business demands."
The company's first UK contract was with BT in 2000 and it has since expanded to take on work from financial institutions and utility companies, as well as print companies, including Xerox, DST Global Output and RR Donnelley.
