发明名称 Contrasted projectile target and method of making same
摘要 Disclosed herein is a multi-sheet projectile target with a marking material that is captively held between a first sheet, which is a target face, and an elastic material located behind the target face. The marking material is selected to contrast with the front of the target face behind which it is located. A surface roughness, on one or both sides of the target sheet, is selected to co-operate with the marking material, so as to accept and retain the marking material on the target face sheet when portions of the target face sheet are exposed to the powdery form of the marking material.
