The High Wycombe-based commercial printer, which signed for the press at Digital Print World last year, has brought all of its personalisation work in-house with the kit, which replaces an earlier Indigo 1000 model.
Your Print Solution managing director Steven Brown said: "We knew we wanted to stay with HP because of the great print quality."
He told printweek.com that the firm has had to "double its paper supply" to cater for the increase in on-demand work.
The 18-month-old company has also shored up its finishing battery with the addition of a Morgana DigiFold to complete its Indigo-printed work.
It claimed the new kit had also boosted turnaround times, citing a recent run of four-page application forms for a high-street retailer completed in a single day.
Brown added that such work would have "cost more and taken longer" with the need to outsource the job to another firm.
The HP Indigo press 3500 can print up to 68ppm in four-colour mode or 136ppm in monochrome.
