The Berkhamsted, Hertfordshire-based business will use the machine to finish work produced on an HP Indigo 5000, which is used for run lengths between 250 and 500.
Managing director Dave Davies said: "We print on the Indigo in 16pp sections and these are fed to the DocuMaster for creasing and folding, prior to removal for subsequent binding.
"The DocuMaster is ideal for this application, but we also use it for conventional booklets and even for simple 4pp items that just need creasing and folding."
Technik Group, which also includes pre-press company Technik, produces personalised mailings for corporate businesses and fine art books for private galleries.
