A device for indicating exposure to a pressure. The device may include a base layer, a plurality of microcapsules, and a coating, with the microcapsules being disposed between the base layer and the coating. The microcapsules contain a indicator material that can be released once the microcapsules burst. The microcapsules then have a compressive bursting strength that is chosen or designed to be less than a selected pressure (e.g., the pressure being that to which a particular article may be exposed during high pressure processing). Thus, when the device is subjected to a pressure greater than the compressive bursting strength, at least some microcapsules burst, the indicator material is released from the microcapsules, and the release of the indicator material can be detected by observation of the device. The device may be a label that is associated (such as by being affixed) to the article being subjected to pressure (or multiple labels being associated (such as by being affixed) to multiple articles. Alternatively, the device may be associated with an article or articles without being affixed thereto.
