Photoshop already offers a number of different libraries included, including ANPA, FOCOLTONE, PANTONE and TRUMATCH. Such ACB color files can be created with a certain amount of effort. To be able to use your own file, you have to save it under 'Preferences / Color libraries' in the Photoshop program folder.
