The direct marketing specialist can now produce 300m images a month at the site following the investment in two Muller Martini Progress S presses and a Printmaster GTO 52 for short-run work.
The investment comes just weeks after the group bought Manchester printer Ward Knowles out of administration.
Bob Harkins, managing director of Paragon, said: "As the trend towards more targeted marketing has increased, this has driven the need for shorter run lengths and quicker set-up times.
"The new equipment allows us to support these trends and provides the flexibility and cost effectiveness that our customers require."
Stuart Scott, sales and marketing director at the group, said that the company was benefiting from clients seeking the safer shores of larger, more secure companies during the recession.
"In the direct mail sector, the supplier base is shrinking faster than the market and the balance of power has adjusted to the stage where we are now in a position to choose our clients," he said.
Paragon Group employs 1,100 people across 14 locations in Europe and has revenues of €160m (£140m).
