In recent years, different methods were proposed for characterization of inkjet printers. The objective of this research is to produce output prints that are spectrally matched to original colors. The simplest model is the ideal ink or Block dye model. The physical model of the printer is generally based on the well known Yule-Nielson modified Neugebauer equation. The ink-paper interactions and the dot gain characteristics play very important roles in printer characterization and hence are studied thoroughly in this work. Moreover, the additivity characteristics of the inks are studied. In the present work, a spectral hue error correction factor has been introduced. The proposed model offers minimum color difference with input data. The correction factors for different primaries have been measured depending on the spectral characteristics of the inks and are incorporated in the equation. The output print quality has been assessed in three different printers with IT test target as well as other color patches. The suggested model with the correction factors offer better color matching with minimum ΔE00 in comparison with the existing Yule-Nielson modified Neugebauer equation.
