I have a client, that has used a certain color in a series of textfields throughout the document.
The color consists of all 4 CMYK colors and needs to be just Keycolor. However the color is not in the swatches menu, so marking it there and changing it won't work. I have downloaded a script that might have worked, but it could only find colors that were in the swatches palette. (Find / Change by Color / Overprint" version 1.2).
Ofcourse, creating a similar color and adding it to the swatches doesn't work.
Is there anyway that i can search for the color or does it really have to be done manually.
You can only search for real, actually existing swatches. No sweat: use "Add Unnamed Colors" in the Swatch panel dropdown menu to get a list of all of the manually applied colors.
Since you want to change all of them to the same color, you don't even have to use Search/Replace. Simply delete the new colors and select the one you need in the "Replace With" dialog that appears.
