Chromatic Technologies Incorporated (CTI, Colorado Springs, Colorado) has introduced Tamper Alert – a new irreversible, heat-activated ink technology that identifies tamper evidence in labels and packaging, primarily for chemicals, pharmaceuticals, food, electronics and other products targeted for theft and counterfeiting. “CTI’s newest technology is a breakthrough in tamper-evidence providing customers with a tight activation window where the alert transitions from colorless to full colour within a range of 10° C,” said the company. Traditional, irreversible technologies require a transition window between 30° to 50° C (86° F to 122° F). This results in weak colour activation and detection at lower temperatures. The new Tamper Alert technology is available in target activation temperatures of 50° C (122° F), 60° C (140° F), 70° C (158° F) and 80° C (176° F). Tamper Alert is currently available only in water-based applications.
