callas software GmbH
callas software was founded in 1995 and has focused on making PDF files usable in production environments from the start. While PDF was designed as a flexible and open format, using it reliably in production – where standardization matters – often proves challenging. callas develops technology to identify PDF files that will cause problems in production and to address those issues early in the workflow.
Close involvement with end users, OEM customers, and standardization bodies keeps the software aligned with real-world production requirements. Working with imperfect, real-world PDF files has resulted in software with a learning curve, designed to control complexity rather than hide it. The callas products actively correct PDF files, prepare them for production, and generate derived outputs such as proof sheets, order overviews, delivery documents, or archived content.
callas is primarily active in print production, document exchange, archival, and accessibility workflows.
