Writing software to handle difficult, real-world PDF files requires deep familiarity with both the PDF specification and the environments in which those files are produced. callas is a team of experienced PDF specialists who have learned where specifications end, and practical solutions begin.

The technology requires effort to master because it is designed for automated use in complex production environments. It is integrated by more than 75 OEM partners and used by tens of thousands of end users worldwide, in workflows where flexibility and reliability matter more than simplicity. Regular exchange with production specialists at pdfCamp and industry events helps keep the team focused on real-world requirements.

Standardization plays a vital role in bringing order to complex workflows. callas actively contributes to industry standards and initiatives, including ISO, CIP4, the European Color Initiative, and the Ghent Workgroup, and is a founding member of the PDF Association.
