The company has just invested in a Morgana Systems DigiCoater UV coater, a DigiFold 5000P creaser/folder and a KB2000 perfect binder.
The investments complement the installation of a CardXtra, a Foldnak bookletmaker and a collator earlier this year.
According to the company, the investments in finishing equipment have allowed it to grow in difficult times.
Peter Martyr, partner at GP Print, said: "Our decision has been vindicated by an encouraging uplift in business from customers who want to add value to their products through a range of finishing options."
The company invested in the DigiCoater to help increase its environmental credentials. The machine offers a "greener" alternative to lamination and output from the machine can be both recycled and it is biodegradable.
