Ghent’s PDF Output Testing System

If you or your printer want to discover whether your output workflow correctly handles PDF files, you can download and print a special set of files from the vendor-neutral Ghent PDF Workgroup, a volunteer organization composed of leaders in the PDF production world. 

The free Ghent Output Suite version 3.0 includes several PDF test patches that, when printed together, clearly display problems with overprinting, font substitution, color issues, white overprint, rendering intent, and more. The update also updated the test files and documentation to make the tests easier to understand.
