Approximately 130 staff have transfered from Future to Immediate Media after shareholders approved the deal last week.
Immediate chief executive Tom Bureau said: "Today we welcome an array of world-class special interest brands into the Immediate portfolio. I'm delighted that these internationally renowned and incredibly talented teams are joining us at such an exciting time for the business.
"They are an ideal strategic fit as we drive our vision to develop new commercial opportunities around strong branded content, delivered across many platforms to our highly engaged affluent audiences."
Immediate was not available for comment on where the Sports and Craft titles are currently printed or whether it plans to put the work out to tender following the acquisition.
Immediate's primary print supplier is Polestar although William Gibbons & Sons is understood to produce a significant number of the specialist titles managed by Immediate's Bristol office and was also a significant print supplier to Future.
