Digipak- What to include?

After looking a various digipaks both online and at home, we soon realised that they have their own set on conventions that are clear to see. All the digipaks I viewed have many things in common including:-

• Dominant image on the front, either a logo, band member or actor.
• Band/artist name is clear on legible on the front cover.
• Album name is located either underneath the band name or at the bottom of the album cover. This is once again clear and legible.
• Track listing on the back.
• Bar code located at the bottom of the back page.
• Same style image/background carries on inside the case.

I need to ensure that our digipak meets this set of conventions.
