I have a customer, which finds it very difficult to give me grayscale pdf files. There is always something RGB or CMYK or SPOT (pantone black) in it.
I want to create a flow with Enfocus Switch for him where he can drop his files, and return in grayscale to him. (so he can check them and than give me the final PDF)
What is the best way to convert the pdf to grayscale in a switch flow?
- use the Action list option "Convert color to gray en keep black text"
- use acrobat professional to do this
or is there a better option???
(I have the total Adobe CS5 package, Pitstop Server 11)
