callas software

Learn about the callas software products, the PDF format, and standardization. As a professional dealing with PDF in print, archival, or accessibility, there is no better source of information for you. As soon as PDF was used in print, long-term archival, and accessibility, callas software had software supporting PDF workflows.

We not only make software, we also help make international standards through participation in ISO, CIP4, the European Color Initiative, the Ghent Workgroup, and the PDF Association. With experience around PDF since 1997, there is no part of the PDF technology landscape that we can't help with. Overprint, ICC and DeviceLink profiles, preflight, transparency, ink coverage, dielines or cutcontours, extra separations, resizing, splitting, merging... there is too much to mention.

We enjoy sharing what we've learned over the past 30 years - follow along with us here!
