Abstract

Utilizing the situation that except image in
visual part of the spectrum can be broadened
to near infra red domain that is observed
instrumentally, near infra red technology stated
its principles. Visual color management leads
and controls both domains applying standard
reproduction materials. CMYKIR separation
principles allow attacking the secondary
monochrome image to visual colored one,
implementing achromatic principles. As the
same color visual output can be performed
on various ways, besides mathematical
calculations, for accurate reproduction twin
colors system is practiced.

Keywords

visual domain; near Infrared domain; color management; under color reduction; CMYKIR separation
