Thomas Potts has bought a 75% stake in a web-based service which allows customers to store text and images in secure online password-protected areas.
Press4Print.com is being beta tested by four clients before its official launch in June.
Thomas Potts chief executive Paul Smith said: "It allows customers to pick and mix data and do their own design." He said the service would be ideal for promotional material and in-house printing needs.
The system was developed by Gary Lawson, who is managing director, Brian Noakes, an employee of Potts subsidiary G&E 2000 who becomes technical director, and software development director Phil Robinson.
Smith said there was "no technical limit" on the amount of data that customers can store. "It simplifies pre-press operations and is another step beyond electronic print brokering," he added.
"Its a snip at 250,000," he added, "and a snip at ten times that amount. We had to move very very fast."
Chairman Stephen Hargrave said G&E 2000 would handle some of the printing, and the rest would be outsourced to the "most appropriate" digital printers.
Hargrave said Potts was looking to make further acquisitions in the digital sector. "We are talking all the time with various people but we are not about to make any announcements," he added.
