The company, which supplies print to the UK through its website PrintExpress.co.uk, has installed a Horizon StitchLiner 5500, a BQ-270 perfect binder and an AFC-566F folder from Intelligent Finishing Systems (IFS).
Synchronised's purchase also includes the UK's first pXnet bindery management software, which was launched in the region by UK distributor IFS at Ipex 2010 in May.
According to director Murtaza Daya, the company made the investment after purchasing HP Indigo 7000 and Kodak NexPress digital presses, which were to complement a litho arsenal that included Komori and Heidelberg machines.
He said: "We had been outsourcing finishing for the past seven years, but when we invested in digital presses to support our litho, we realised it was time to have our own bindery capable of flexibly finishing both."
According to Daya, the StitchLiner's ability to work from flat four-page sections eliminates the need to pre-fold into signatures or pre-trim top and tail, resulting in significant time, waste and energy savings.
The company currently has a worldwide turnover of $25m (£16.2m), but has said it is targeting sales of more than $100m in the next 12 months, which will include an aggressive acquisition of customers, businesses and equipment.
As well as its London base, the company has offices in the US and India.
Synchronised added that it is working towards building what it claimed would be the UK's first "digital super factory" that it hopes will become world renowned.
