A new add-on to d'accord Pro allows to replace colors in PDF files.
You'll probably know this problem: Some customers PDFs contain specially defined process colors which you have to replace with certain spot colors in the ready-to-print PDF. For example, 100% Cyan as a placeholder for a specific PANTONE® color.
With the new add-on for PDF color replacements, you can easily and reliably compare the customer artwork in such cases to the printable PDF. d'accord matches the colors of both PDF and displays only the differences that really matter to you.
