- In a dust jacket, this is the part that wraps around the casing board, joining the front and back covers of the dust jacket to the flaps. In a properly designed dust jacket, the cover artwork extends into this part of the jacket so that the white of the flaps start after turning to the inside of the casing board. In an improperly designed dust jacket, the flaps start along the edge, which looks like an error in printing.
