Durst Group aims to strengthen its software strategy with addition of prepress and PDF specialist callas
The Durst Group, maker of digital printing and production technologies, announces the acquisition of callas software. callas provides prepress automation and PDF technologies and plays an essential role in many print workflows – either directly or as an OEM component in leading prepress products.
The Durst Group aims to strengthen its software strategy with this acquisition with a focus on openness and connectivity within the printing industry. The objective, say Durst, is to achieve intelligent, seamless automation between machines, software, and print processes. At the same time, callas software will remain autonomous in its management and product development.
A strong message to customers and partners
For callas customers and OEM partners, the acquisition brings greater stability and new technological opportunities. callas continues to operate as an independent company but with the resources of the Durst Group, it can continuously improve its technology. Existing customer relationships remain unaffected.

The acquisition provides wider integration options through access to Durst Group’s software technologies.
“Maintaining callas’ independence was a central requirement for joining the Durst Group. Our customers must be able to trust that callas will continue as a reliable partner – while also gaining a new foundation for long-term innovation,” says Dietrich von Seggern, CEO of callas software.
Digitalisation and automation as a shared vision
With the acquisition, the Durst Group intensifies its strategy to build an open and connected software platform for the printing industry. callas will play a key role in connecting isolated solutions and enabling print service providers worldwide to achieve greater efficiency, scalability, and flexibility.

In the coming months, the collaboration between callas software and the Durst Group will deepen. The goal, say Durst, is to leverage synergies and accelerate the development of an open, vendor-independent software platform for the print industry.
“This is not just another step towards digitalisation – we are actively shaping the future of digital printing. With callas at our side, we are making print software smarter, more connected, and more powerful. The best solutions arise when strong partners work together toward a shared vision,” says Christoph Gamper, CEO and co-owner of the Durst Group.
