PANTONE has recently made available the PANTONE PLUS Digital Libraries Installer. The installer is a free utility that allows you to integrate the PANTONE PLUS Libraries into Adobe Creative Suite.
The PANTONE PLUS Series is an enhancement to the PANTONE Matching System and retains all of the previously existing PANTONE Matching System colors.
To obtain the new libraries, download the installer for your operating system from the PANTONE website: http://www.pantone.com/colors4adobe.
Read the information provided on that download page. For more information, download the PANTONE PLUS Color Library Technical Notes from the same page.
