Sherwood Technology has launched DigiVU Microread, its newest color change solution to provide high-level features for product and brand protection. DigiVU Microread uses a combination of proprietary chemistry, a variable, tunable laser source, and individual control system to form a series of unique overt, semicovert, and covert features.
Ultra high-resolution images are reproduced by a variable digital imaging process in microscopic scale, making them virtually impossible to decipher with the human eye. Upon magnification, however, the images become an effective authentication tool.
