Style Guide 'Color Reference'
The 'Color Reference' Setting on the Style guides defines the naming convention for the reference image send to the post-production vendor. To be able to edit this naming convention 'Color matching' needs to be activated on the workflow level.
Per default the naming convention is set to '_color-ref-ProductCode' which gives the reference a unique naming and a clear association to the product to be color matched.
You can adjust the naming convention by clicking in the text field. Mandatory to use for the naming is the property ProductCode. Besides normal text, you can also add additional properties which can be selected via a click on the icon below.
