The East London company has bought a DC 445 DuCreaser, an Ideal guillotine and a DBM 120 Bookletmaker and trimmer.
Managing director Simon Jones started the company, which currently employs four staff, in April this year.
The company has a Xerox 6060 and Xerox 8000AP, as well as an HP 5500 for large format work.
Jones said: "We wanted to make sure the work was coming in before we invested in the finishing side; there is no point in having it if you have no work.
"But it is going well; they say surviving the first year is the toughest thing and we are definitely on course to do that."
Trilogy handles work including business cards, flyers, brochures and presentation documents.
