To unlock a full comic, you must collect Cog Tags to unlock the pages. There are five total comics that you can read, but you only need to read one of them. Once you have unlocked a full comic you can view it in the 'Extras' menu and select the comic you wish to read. You can then scroll through the comic using the [RT] to the end and the achievement should unlock. If it does not, utilize the zoom function with (A) and slowly 'read' each page.

This can be a little glitchy for some reason. I had to 'read' a comic a few times slowly to get it to unlock. Some have reported that coming back the next day and reading the same comic has resulted in the achievement.
