Abstract

See full text

Examples are directed toward anticounterfeit markings printed on a substrate. A method includes determining with a microprocessor running computer executable code non-transitorily stored on tangible computer readable media that: a first microprinting appears on a front side of the substrate as front side markings of first portions of a plurality of characters having dimensions in a micrometer range when viewed from the front side with reflected light, a second microprinting appears on a back side of the substrate as back side markings of second portions of the plurality of characters having dimensions in the micrometer range when viewed from the back side with reflected light, and the first microprinting and the second microprinting in combination appear as microprinting of whole characters of the plurality of characters when viewed with transmitted light.
