A reimageable medium for receiving an imaging light having a predetermined
wavelength scope, the medium composed of: a substrate; a photochromic
material capable of reversibly converting among a number of different
forms, wherein one form has an absorption spectrum that overlaps with the
predetermined wavelength scope; and a light absorbing material exhibiting
a light absorption band with an absorption peak, wherein the light
absorption band overlaps with the absorption spectrum of the one form.
