The takeover will see all nine staff members at the £800,000-turnover City Litho moving across to Paramount.
City Litho’s sole shareholder, director Jim Cree, will retire after employees are integrated into the new-look company’s Causewayside site, which will employ a total of 21 staff.
Paramount Printers managing director Paul Hepburn said the companies had enjoyed "a fantastic working relationship" for years and called the acquisition an excellent fit.
He said: "Paramount will now be in a position to offer an unrivalled printing service to clients with the addition of City’s experience, expertise and presses.
"It’s the amalgamation of two profitable companies that have built a strong relationship over many years after working in partnership on numerous projects that complemented each of their strengths."
According to Hepburn, the company aims to grow its presence in the direct mail and election printing space, building upon recent successes, such as a six-year £500,000 print contract with the Scottish parliament, which it was awarded last year.
"With the increasing popularity of highly personalised direct mail, it’s the perfect moment to introduce a full-colour flat-sheet element to our range to complement recent investment on presses, software and finishing equipment," he said.
City Litho’s machinery, which includes a Komori five-colour Lithrone 528 with infrared dryer and a four-colour Komori Spica, will also move to the site.
These will join Paramount’s set-up that includes a Heidelberg Speedmaster 52, three Heidelberg Quickmaster presses, a Halm EM5000 full-colour envelope printing press, two Konica Bizhub 1050 and 550 digital machines and a Buhrs BB300 mailing line that was installed last year.
City Litho also brings a client list that includes Lloyds and the Royal College of Surgeons. This complements Paramount’s customer base, which features the Scottish Parliament and General Teaching Council.
Hepburn added: "The range of machinery will allow us to plan cost-effectively any kind of print job – from digital printing to simple one-colour business cards to full-colour double-sided jobs with spot colour or varnish.
"Our clients will benefit from an expanded set of skills and technologies seamlessly integrated to give maximum efficiency and quality."
