Abstract
Methods for providing pharmaceutical compositions and objects with identification regions and identification features which are difficult to detect. Microlithography, nanolithography, and stamping methods are used. The identification features can be positive protrusions or negative indentations with respect to the surface. The identification regions can comprise bar codes and holograms. DPN printing or other lithographies such as electron beam lithography, optical lithography, or nanoimprint lithography can be used to prepare stamps, which are then used to prepare the identification features. Redundant patterns can be formed. The invention is useful for counterfeit prevention. An apparatus for stamping the identification features is also described.
