Abstract

Dual images printed on fabric are achieved due
to INFRAREDESIGN®, through twin colors
basic. Tentative part is performed on cotton
fabric through CMYKIR technology principles of
separation and matching of colors. Sophisticated
barrier scanning while procreating testing model,
is performed for ultraviolet, visible and near
infrared part of the spectrum.
This method leads to moving boundary scope of
security printing and dual information to a variety
of possible printing substrates and sheltered
information to materials like silk, cotton, leather,
polyester and similar by appliance of twin
colors and dual information. These diversity of
possible substrates, variations in dyes mixture
combinations and coverages allows technologist
and designers wide field of concepts, projects
and acquirements. IRD technology is based on
developing and forming “twin dyes”, whose
spectral characteristics for this appliance, some
here are presented. Also some additional tools
for better visual twins matching are introduced.
All observed twins render same spectral
characteristics designated as Z domain, beneath
900 nm area with ΔZ difference for “visual and
NIR” dyes.
