Use Adobe Illustrator to convert CMYK colors to the Pantone Matching System. Illustrator has an option to match CMYK, or cyan, magenta, yellow and black, to Pantone colors without the need to buy Pantone bridge books with the conversion information. Though it costs money to use Illustrator, Adobe offers a trial version on its website, providing 30 days of use before the trial ends.
- Import the CMYK illustration
Open Adobe Illustrator, and import the illustration that uses the CMYK color mode. Press the Ctrl and A keys to select every color in the illustration.

After selecting the appropriate color book, click OK in the dialog box. Wait for Illustrator to convert the CMYK colors to Pantone colors. Save and print the image as needed. Close Illustrator.
