An impression that is created when surface contact is made, but instead of a deposit occurring, something (e.g., dust) is removed from the surface. For example, as a hand is removed from a dusty surface, the dust adheres to the friction skin, creating a void on the surface. The resulting detail is reversed, in that the dust-free area of the impression is replicating the friction ridges, and the remaining dust, the furrows.
