Abstract

From the graphic arts point of view, whose principles are often practiced in NIR technology, the secondary image is actually nested in the visual extent of the primary image. As the procedure basically does not enforces any hidden or special inks, materials or substrates, secondary image information is nested in spectral properties of basic colorants. As visual and NIR domains are separated, spectral differences argument for creating double images. NIR image is nested according to K ink achromatic interchange, and visualized in NIR domain by a separation process from the visual part.
