The company went into administration with insolvency practitioner BDO on 28 July and was sold to DG3 the same day.
All 26 employees will move to DG3 under TUPE regulations in a deal that should boost group turnover to £14m in 2011.
DG3 Europe chairman Peter Furlonge said that the two companies had a relationship for almost 30 years, so it was a personal move as a business one.
He said: "When I heard that FS Moore was going into administration it was very sad, so I did what I could.
"The company was well known for its high-end work, which is an area DG3 does not concentrate on – we can expand into that."
FS Moore produces corporate communications, fine-art books and bespoke creative products and boasts a large number of global clients.
Keith Arnold, managing director of FS Moore said: "We are extremely excited at the opportunities joining the DG3 Group will bring to our business.
"We feel secure in the knowledge that we will continue to demonstrate the high quality our clients demand and add exciting new communication services, while providing our clients with outstanding service."
