The company, a division of Norfolk County Services, is housing the machine in its new premises in Norwich, and is producing a range of multi-colour work including brochures and folders.
Interprint, which has a turnover in excess of £1.7m, was previously carrying out work on a range of single and two-colour Heidelberg presses and has experienced significant time savings with the new Shinohara.
Manager Tony Matless said: "A job that would previously have taken us around 10 hours is now taking three or four."
He added: "The press is absorbing a lot of the work we were previously sending out to other printers, this machine will help save on those costs."
Interprint prints for Norfolk County Council and commercial clients, such as those in healthcare and education, and Matless anticipates the new four-colour will help attract additional work.
"We are now in a position to produce higher quality colour print as well as providing a prompt service to many council departments," he said.
