Abstract
This paper provides spectrograms of the light
absorption for the process digital color printers.
The INFRAREDESIGN® method is based on
"twin" colors. Colour equality implies the space
of the spectrum of light seen by the naked eye.
The IRD expands to the light in the near infrared
area which is observed with an infrared camera.
The numerical value Z, which is manifested as the
absorption force of light at 1000 nm, is detected
by an infrared camera.
The design with double V and NIR graphics
introduces a new size of ΔZ that measures the
absorption difference of two dyes at 1000 nm.
Colour equality and inequality in two spectral
domains is shown with a spectrogram.
