    摘要: In a secure imaging system for securing documents or encrypting images, an image comprises an array of printed positions formed using a group of inks each having a predetermined spectrum. The positions are selected to form a predetermined image, either real or virtual, when the image is viewed through an optical processor. An image formed using inks having the same colors as experienced by the human eye, but not sharing exactly the same spectra, will fail to form the correct predetermined image.
