Abstract: An improved target label for shooting that includes at least one toner layer defining an image of a target, superimposed over a colored substrate having a color different from the toner layer, and an ink layer underlying the toner layer. When a projectile strikes and penetrates the target, the ink and toner layer displaces and scatters over an area surrounding the point of penetration, exposing the underlying colored substrate layer. The scattering of toner particles visually resembles gun powder and visually simulates damage over an area wider than the point of penetration by the projectile.
