Abstract
Disclosed is a thermal transfer ribbon for use with a media processing device. The thermal transfer ribbon includes a carrier layer and a transfer layer operatively coupled to the carrier layer. The transfer layer includes an environmental indicator material encapsulated in a plurality of microcapsules. The plurality of microcapsules prevent the environmental indicator material from producing an observable effect in response to exposure to a predetermined environmental condition. The environmental indicator material is released from the plurality of microcapsules in response to the plurality of microcapsules being ruptured. After the environmental indicator material is released and exposed to the predetermined environmental condition, the environmental indicator material produces the observable effect. The observable effect results from a change in the environmental indicator material from an original state to a second state in response to the predetermined environmental condition.
