Optimizing Separation Parameters for Dedicated CMYKIR Reproduction Purposes With Hidden Double Information

Abstract

Contemporary programming support for image correction and manipulation for
graphic arts purposes implies partially regardless RGB/CMYK separation options,
where particular parameters can be adjusted separately or by means of ICC profiles.
As input image information can be reached from different dynamic range devices
or can be generated, output reproduction devices can use various substrates and
media, so additional adjustments and researches have to be carried out. CMYKIR
reproduction has specific demands, while through the visual part of the spectrum
(VS) colour management controls response and experience outside the visual, i.e.
hidden information in the near infrared (NIR) domain, and claims to find dedicated
adjustments for specificities of VS-CMYKIR reproduction.
