Abstract
The paper presents an investigation of the effect of different values of total area coverage of inks (TAC) on the color gamut and color reproduction accuracy on color proof. For the study of the effect of TAC values on the color gamut, we have a used special test form. According to measurements of the reflectance spectra of test charts, we have compared the color gamuts with different values of TAC to obtain comprehensive information of all colors, which could be reproduced in the specific conditions. In order to obtain complete evaluation of the changes in color gamuts depending on TAC value, the color gamut volumes and surface areas of 2D cross-sections were calculated. In addition we have converted the reflection spectra data to CIEL*a*b* coordinates, and have calculated the color difference, δE* ab to determine the effect of TAC on color reproduction accuracy. A practical implementation of the correct value of total area coverage should improve the printability, better ink layers adhesion, biggest number of trapping values and reduce the quantity of process inks.
