“Preflight is necessary, with the very few exceptions of completely closed workflows. However, using standards is essential for success”, explains David van Driessche, autor of the white paper and Chief Evangelist at callas software: “Luckily, today’s software widely supports the available preflight standards, which work well together. As a result, you can use Ghent Workgroup standards that are based on PDF/X. Your own company-specific rules can be added on top. The differentiator often is how the results of preflight are handled.”

This white paper provides specific answers to questions such as

• what happens when errors are reported, and who are they reported to?
• what about warnings, specifically in automated workflows?
• what can, and should be corrected, and how?

While much of this white paper contains general information, callas pdfToolbox provides concrete implementation solutions wherever possible. This is particularly true for the chapters discussing variable profiles and their capabilities to keep workflows simultaneously flexible and lean. And when talking about specific technologies such as process plans, that allow for sophisticated PDF handling that goes far beyond mere preflight.
