The StitchLiner, which replaced a Duplo line, was brought in to handle growing demand for bookletmaking and short-run work.
The kit, supplied by GAE, has cut outsourced finishing and can turn out work in a fifth of the time of the previous set-up, with single-pass collating, stitching and trimming.
Printability director Dean Newman said: "We do a lot of sporting programmes in runs of 1,000-2,000 around 56 to 72 pages, which used to take five or six hours to complete, but the new StitchLiner finishes the work within the hour.
"We are sending a lot less work out now. It has reduced our outsourcing by 50% and it's putting £3,000 onto the bottom line every month."
The extra performance on short-run work has meant the company had the capacity to bring forward its planned move into digital.
Newman has already launched Printability's Rubicon Digital division, at the heart of which is a recently installed Xerox machine.
"We spent a good deal of time researching this investment, but it has been one of the best decisions we have made. I am delighted," said Newman.
Printability runs two five-colour Heidelberg Speedmasters and employs 38 staff. It has a turnover of £3.5m.
