The enclosed XTension will add an “All To Process” menu item to the Utilities menu. If you select it, it will change all colors in the current document to process. There isn’t an Undo, however. Also note that you can avoid adding colors to the color palette from imported documents by holding down the Command key when importing or updating EPS files. Hope this helps. I wrote the thing in about half an hour in response to a few recent requests on the QUARKXPR list.
I’m thinking about adding a “Delete All Unused Colors”, and making it recognize colors that normally can’t be converted to process (Pantone Metallics and Florescents), and giving you the option of changing them (currently it goes ahead and converts them). I don’t know how soon I might get back to this.
