The document reviews conventions used in music posters and digipaks. For posters, the main conventions are a large central image of the performer, large readable fonts (especially for the artist name), limited colors, and key release details. For digipaks, conventions include multiple related images across panels, the largest image on the front, text details like the tracklist and credits, continuity of fonts and colors across panels, and genre-appropriate color schemes. The conventions help quickly convey key information to potential buyers.
