Please see the screenshot beneath. I'm using Adobe Acrobat Pro DC Version 2019.010.20064.

I'm trying to convert the book's default (C, M, Y, K) = (99%, 98%, 18%, 6%) (ie dark purple) to (90, 0, 90, 0) (green). After I click 'OK' and click 'Fix', Adobe Acrobat executes the fixup, but the color fails to change.

  • Just a guess: are you sure the PDF is CMYK and not RGB mode?

  • @jhurley Did you manage to download the PDF? 'Output Preview' exhibits CMYK percentages not RGB.

    @Greek-Area51Proposal Please don 't ask people to download things. We're a bit weary of download links, because users never know for sure what they are downloading. If you are having specific problems, use (annotated) screenshots to illustrate them.

  • @PieBie If I remember, didn't someone ask me for the PDF so that he can download it? Was that comment deleted?

  • Yes. See my previous comment. We do not allow questions that depend on external files. Questions need to be self-contained, and potentially useful to others. If your problem cannot be solved without access to the original file, then it is a technical issue and not a design issue and it is out-of-scope for GDSE.

Not sure what went wrong at your end. I have used the exact same settings as you (see attached screenshot) and it worked as expected. What version of Acrobat are you using? enter image description here

  • I have tried 2018.003.00009 Windows and 2019.010.20098 both without any issues. Can you import (via the options menu at the top right) this profile and try it link? Apr 25, 2019 at 10:15

    The Profile that you have sent uses wrong input color (other than in your initial screenshot): C97 M55 Y28 K7 instead of C99 M98 Y18 K6. When I modify your profiles values it works as expected. May 2, 2019 at 9:28
  • Hi! Sorry for the delay; I forgot about this. Where do you see "C97 M55 Y28 K7"? As you can see, I input " C99 M98 Y18 K6" in my screenshot.
