Chromatic Technologies developed a patent-pending, high-pressure indicator “ink” applied to a food package that indicates high-pressure pasteurization (HPP).
This anti-counterfeiting, HPP-indicator technology is delivered via an ink that can be printed on the exterior of most retail packages. The ink is clear when printed and then increases in color as it’s exposed to the high isostatic pressures found in the HPP process. The ink comes in water-based and ultraviolet cured inks.
