Abstract

  • A near infra red (NIR) designed image is a dedicated image containing additional information in a spectral domain between 700 and 1000 nm. Throughout management in visual spectrum z-parameter properties of selected separation or custom dyes are adjusted for NIR visualization. If such reproduced image is rescanned, Z-parameter properties of a CMYKIR designed image vanishes, or is seriously damaged.
