Abstract
We are observing duo images with double cameras that we have developed for the further development of infrared information VZ technology. The spectrum range goes from visual (V – RGB) to the near infrared spectrum (Z – NIR). We have developed procedures by reproducing a fine art work that contains a double image. The digital reproduction contains the same content from two images. The original fine work and the printing reproduction have been performed by different procedures, different dyes. Spectral analysis of painting and printing dyes has been performed. In this paper we are publishing a mathematical model of VZ separation of dyes in order to achieve reproduction of double images information on silk. The new model is based on twin dyes that have resulted from the experimental work with printing on silk and measuring their equality. We are using the spectral analysis of light absorption in the range from 400 to 1000 nm. The goal is to find the shortest way to fix the content of process dyes in the ensuing printing experiments. The results of development of hidden image information are being demonstrated on safety clothes.
