Durst Group, a global supplier of digital printing and production technologies, has announced the acquisition of callas software. callas is a provider of prepress automation and PDF technologies, and it plays an essential role in many print workflows – either directly or as an OEM component in leading prepress products.

With this acquisition, Durst strengthens its software strategy and focuses on openness and connectivity within the printing industry. The objective: intelligent, seamless automation between machines, software, and print processes. At the same time, callas software will remain autonomous in its management and product development.

For callas customers and OEM partners, the acquisition brings maximum stability and new technological opportunities:

• Long-term security: callas continues to operate as an independent company.
• Guaranteed advancement: With the resources of Durst, callas can continuously improve its technology.
• Unchanged OEM contracts: Existing customer relationships remain unaffected.
• New opportunities: Expanded 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.

Digitalization 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 Durst will deepen. The goal: to leverage synergies and accelerate the development of an open, vendor-independent software platform for the print industry.

“This is not just another step toward digitalization – 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.
