Font Consistencies
Arctic Monkey's album, The Jeweller's Hand, is a prime example of an inconsistency in fonts. On the left is the magazine advert for the album, while the album cover itself is to the right. They are not entirely dissimilar but there a definitely obvious differences. For example, the magazine's font is much more square and blocky, as well as full, whereas the album cover is deliberately missing patches.
Jesse J's Who you are simply used the digipak's cover in the magazine advert. This should mean the font is consistent, as one features the entirety of the other, but the text bellow is completely different to the main titles. The digipak uses curly, handwritten looking fonts, while the details given below have a blocky, simplistic font. The only way all three fonts are linked is that they are all sans-serif.
Florence and the machine's album Lungs also uses the album cover within their advert, though they make it rather more interesting by cropping the photo and editing the colours. Unlike Who you Are, the accompanying text outside of the original image uses the exact same font as the album's title. However, the logo used for the band is in a different font, as it is used elsewhere to just this album.
Overall, it seems that no digipak aligns their font perfectly with themselves or their corresponding magazine advert. Yet they may still hold some similarities, such as the same style of font rather than identical, or even consistent colours.
