I needs to look like it looks here with three different pics for screen printing. Is there any way to do this quickly or do I have to do it manually?
What I do...
Then save as PDFx-1a so it separates properly.
I'm not a screen printer though :) There are others here with far more experience in screen printing than I have.
If you aren't doing the screen printing yourself, it's best to let the actual screen printer handle the separations.
You should be able to just save as PDF. Select a Preset like PDF/X-4 so it does not covert your color with a color profile.
If you have Acrobat Professional, you can open up the pdf and check the plates. Under Advanced / Print Production / Output Preview you see a new pallet.
Choose the profile for U.S. Sheetfed or U.S. Web (don't think it matters.)
You see a check box next each of your colors.
Check them all off, if you see any objects with just CMYK checked you'll have to go back and fix them. You should only have objects on your three spot plates.
Adobe still (as far as I know) asks us to print to separations. Here's their instructions.
For absolute clarity, I follow a different process (that may just be a waste of time ;).
Sidenote: The outer paths under "altitude" don't line up correctly.
