The software now has a file comparison feature that visually highlights any differences and includes batch processing so that a quality control profile or a single fix-up can be run on a whole folder of files.

The system also boasts broader support for other file formats, adding Microsoft Publisher, Project, Visio as well as Apple Keynote and Pages to its roster, and by including Adobe's distiller engine PostScript and EPS image files can be converted to PDF.

The latest version also fully supports the ISO 16612-2 standard for variable and transactional workflows: PDF/VT as well as GWG Proof of Preflight standard which digitally signs files so that subsequent changes can be detected.

Finally intelligent fixes have been expanded to include a fix with the ability to automatically detect printer marks and set a correct trimbox and bleedbox based on those printer marks.

Both desktop and server editions of pdfToolbox are available now priced from €499 (£443) and €3,999 respectively with a time-limited trial available from the Callas website.
