The Leicester-based company researched the market for 18 months to find a machine, and it said that tests showed it took two and a half hours to print what it would take two of its other machines 40 hours to do.
Alan Farfort, director at Data Image Group, said the company also purchased the press because of its "exceptional high quality print".
He said: "We saw fantastic quality print samples from the Onset 40, and once we conducted tests we realised the potential it had to move our business forward.
"It can produce up to 470sqm of print per hour and the configuration of the print heads means the speed and quality of output is phenomenal."
The Inca Onset S40 is aimed at specialist display print companies, and uses up to 168 new-generation, user-replaceable printheads (28 per colour) on a full-width print bar.
This produces 600dpi prints with the option of four or six colours using Fujifilm's UVijet OB ink.
Data Image Group signed for the wide-format UV inkjet printer at Fespa Digital 2011, and it will join a Fujifilm Acuity Advance HS HD3545 later this month.
Farfort was unavailable to comment further.
