Chromachecker automatically defines two tracks for each printer when you use the wizard. One is for Coated Stock and the other is for UnCoated Stock. Each printer starts with the ability to set up 5 tracks and additional tracks can always be added to your license. Note that a track represents a print condition so for each potential target, you will want to have a separate track. 

To make a new track the most efficient method is to select an existing track using the check box and selecting duplicate. This will create a new track with all the same parameters. You can easily change any track configuration simply by clicking on the magnifier to the right of the track and updating the form.
