Abstract

See full text

A printer system includes a memory, a processor, and one or more printer heads. The processor determines a number of transmission layers and a number of barrier layers to use in a color changing expiration indicator based at least in part on a time period between a print date of the indicator and a received expiration date. The printer heads print a reactive layer onto print media, where at least a portion of the reactive layer is configured to migrate through the transmission layers. The printer heads also print the determined number of transmission layers and the determined number of barrier layers in alternation. The printer heads print a reactant layer that is configured to change color responsive to a reaction between the reactant layer and the reactive layer upon migration of the reactive layer through the transmission layers. The reaction is configured to occur on the received expiration date.
