The 12,000 envelope per hour machine was installed at the end of 2012 at the Wotton-under-Edge facility, which was taken over by DCL Print from collapsed Orchestra Wotton in 2011.

It complements the security print facilities and web presses at the Gloucestershire plant, and joins a raft of sheetfed printing and in-house finishing equipment.

The company already has two Kern inserters at its Crawley headquarters, and was keen to invest with the manufacturer again due to the machines’ reliability.

DCL Print managing director Simon Smode said: "We are an extremely busy company, and the team like to feel that they have a set of machinery that they can trust – this is certainly the case with all of our Kern machinery.

"Our company has diversified into mailing and inserting in the past three years, and during this time DCL Print has grown rapidly, building up a strong customer base in the process.

"As a result of our recent growth, the demand for additional machines is continually increasing, and we rely on these mailers and inserters to get the job done as fast as possible."

Smode bought the inserter, which has an integrated folding system, as a secondhand item from Kern, which he said had "enabled us to purchase an inserter without incurring a substantial cost".

The 90-staff company also offers label and card printing through its acquisition of failed Centrereed’s assets, including a Tamarack Specialist 300 printer, and has a Didde MVP five-colour reel-to-sheet press, which it attained from collapsed Weston Business Forms along with its database and four staff.
