Ancillary Text - Conventions and Existing Products: Digipak

As I am creating a digipak as one of my ancillary products I thought that it would be useful to look at the conventions of the main sections of a digipak (the front cover, spine, back cover) and also look at some existing products to see how they have followed or challenged them. I found this really helpful as I now know what conventions are essential, what conventions could possibly be broken and how I can make my product unique without taking away professionalism.
