Abstract
Hidden graphics for visual close infrared (VIS
and NIR) spectrum consists of two pairs of twin
pairs of interlacing colors creating quadruple
dependency as VZ graphics. Two-ton color dye
absorption spectra are introduced, extending to
their twins. Colorant recipe that are made up of
four process colors are enclosed.
Mixing the dyes is interrelated depending on
the recognition in a visual and close infrared
spectrum. Two graphics are independent QR
Codes that are located in the same space. The first
QR code is readable in the visual (V) spectrum
and the second cod is detected by an infrared
camera at a wavelength of 1000 nm. The IR
camera does not recognize, does not register the
first V code. Each code begins with quadratic
elements of two extreme coverage: black (K) and
white surface (W). Overlapping two independent
codes V and Z, determines four combinations
of coverage, with which two colors are realized.
Gray and Cyanosis gray colors form four twins
according to VZ procedures in the VIS and NIR
spectra.
