An article having multiple spectral deposits is provided. The article can
include a support and a single nanomorphic marking material adapted to
reflect light having a first spectral content and adapted to reflect
light having a second spectral content. The article can include a support
and a nanomorphic marking material held by the support that luminesces at
a plurality of wavelengths. The article can include a support and marking
material having a first particle size and a second particle size. The
first particle size reflects a first spectrum and the second particle
size reflects a second spectrum. The article can include a support and a
marking material held by said support with the marking material including
a nanocrystalline particulate having a measurable property
non-characteristic of the same marking material in a bulk state.
