The company is investing in the machine because it is moving from collated to folded-section work to feed a recently installed six-station Stitchmaster ST 100 saddlestitcher.
It will be used to fold work printed on a Heidelberg Speedmaster CD 74-5P, a SM52-5P and two QM 46 portrait presses.
According to director Gary Davidson, the machine will cut makeready times compared to its existing machine, "possibly in half".
Minprint handles a wide range of direct mail and promotional material, and its clients include Belfast-based railway service company Translink.
