They ask me to provide it in a separate file. That is, separations are rarely if never done to PDFs since those are not source material. Ask the creator of the content to provide what's needed.
I was provided with a pdf to print but it is process colors and I have a mix of image and lots of black text. How do I take the black text, remove it and create a seperate spot black plate (layer) to acheive a cleaner text?
