A marking system comprises a substrate having a surface coated with a color triggering developer and a deactivating ink composition; and a marking composition 5 comprising at least one color precursor. At least one "non-color developing portion" of the surface is coated with both the color-triggering developer and the deactivating ink composition, and at least one "color-developing portion" of the surface is coated with the color-triggering developer and is not coated with the deactivating ink composition. Color development occurs at the color-developing portion(s) and does 10 not occur at the non-color developing portion(s) upon application of the marking composition to the surface of the substrate. |
