Here’s a quick how-to on converting Pantone spot colours to CMYK values in Adobe Illustrator:
- Check that your document colour mode is set to CMYK. That’s found under the “File” menu, under “Document Color Mode”
- Select all elements you wish to convert. A quick marquee drag will take care of that for you.
- Head to the “Edit” menu and select “Edit Colors” – “Convert to CMYK” is the 7th item on that list. Select that and you’re just about done.
- Perform a “Save As” so that you don’t overwrite your spot colour version.
