The document discusses conventions for different parts of a digipak album packaging, including the front cover, back cover, spine, inside covers, and behind disc covers. The front cover conventionally features the artist name and album title, as well as the artist image. The back cover conventionally includes the song list, track numbers, barcode, record label info, and copyright details. The spine conventionally displays the artist name, album title, record label logo, and serial number. While inside covers have flexibility, conventions include relating to the overall design and featuring lyrics. Behind disc covers are unconventionally designed with lyrics rather than images to add uniqueness.
