Is it possible to change a color within a PDF using Acrobat?

Apr 6, 2013 7:16 AM

I would like to change a color within a large batch of PDFs.


The color should have been changed in Quark, but now that I'm well into the PDF production cycle, I'm wondering if it's possible to edit the PDF directly.


Apart from color photos, there is only one spot color to be adjusted.

    You need to be more specific about what you want to do. It's possible to make some changes to color profiles and switch spot->process but you can't make arbitrary replacements.

    If the spot plate has any tint below 100% you can't replace it in any automated way using out-of-the-box Adobe software.


    • It's possible to redefine the name and alternative space for a spot plate in Acrobat XI Pro but it has to be done by hand using the Cos editor, there's no ay to automate it unless you write your own plugins in C++.
    • You can demote a spot plate to process color using Ink Manager, then use Preflight to promote a process color (defined using CMYK percentages) to a spot plate, but it won't cope with variable tints.
