Note that the Pantone books have updated the color codes to show Lab values. For example, PANTONE 609C has both a Lab and CMYK value. In addition, due to licensing restrictions, Adobe has decided to remove the color books from the commercial version of its application. The changes are expected to affect users who have purchased an already-purchased copy of the application. The official release notes state that changes were made to the Pantone library for commercial use, removing all Pantone color cards from the Pro and UI tier of the application, with the exception of Pantone TCX, which will remain in the Pro and UI tier. The Pantone website has announced that companies interested in licensing the proprietary Pantone library through its Creative Cloud program can do so for a subscription starting at $149. However, the Pantone library will not be included in the free versions of CS6-derivative applications, such as Fireworks and Photoshop. The announcement further stated that users who have purchased an already-purchased copy of CS5 will continue to be able to use the Pantone library, but should exercise caution when opening the files.
Color codes in current and future Pantone books will retain CMYK values, but other spot colors without a Lab value will be interpreted as CMYK. Some spot colors without a CMYK value will retain their Lab color code. 7211a4ac4a
