Death to the Ghost Pantone Swatches!

Sometimes I end up with unused Pantone swatches in an InDesign file that I can't remove, for whatever reason. I'll go through the separations preview, and find nothing. I'll look at all the linked files in Bridge, and see nothing that contains the offending swatches. After much tearing of hair and searching online, I finally found a tip to remove the ghost Pantone swatches.

1. Create an EPS in Illustrator that contains the Pantone swatches you want to remove.
2. Place the file in the InDesign document.
3. Delete the file from the InDesign document.
4. You should now be able to remove the unused Pantone swatches!
