The new machine has opened the door to a broader set of clients, such as retail, the exhibition market and trade making, said a spokesperson at the company.
The five-staff firm already runs an Océ Colourspan CS7100 alongside two Mimaki JV3 SP machines.
But the Arizona means it can take on work it would previously have had to turn down.
Kokoon managing director David Taylor said: "We chose the Océ Arizona 250 GT because of the excellent quality of its output and the fact that it has enabled us to print things that we would never have been able to do before, in particular for new business pitching.
"For example, for one marketing company, the Arizona enabled us to print on ping-pong balls."
The Océ Arizona 250 GT uses UV-curable inks and boasts Oce's Variadot imaging and piezo inkjet technology to produce variable-size dots for high-quality 600x600dpi images.
It can print on a range of substrates from paper to foam PVC and has a maximum width of 2.5m.
