A copy-resistant coupon including a human-readable section with text formed by reflective areas and dark-colored areas, and a machine-readable bar code section composed of reflective bars appearing in a light-colored background. Photosensitive devices used in copiers and bar code scanners interpret the reflective areas as dark, such that the reflective bars in the bar code stand out as dark in high contrast to their light-colored background, and are easily readable by the bar code scanner, while the human-readable section when copied will show reflective areas and dark-colored areas both as dark with little or no contrast between them and revealing that copying has taken place. The coupons are made with printing methods that apply dark- and light-colored inks to metallicized paper, or apply metallic inks to dark- or light-colored surfaces of papers.
