Abstract

For purposes of defining a feasible approach to spectral color management, previous research proposed an interim connection space (ICS). ICS is relatively low in dimensions and would be situated between a high-dimensional spectral profile connection space and output units. The current research simulated printed spectra after using a multi-dimensional ICS-based lookup tables (LUTs) based on LabPQR, an ICS described in earlier work. LabPQR has three colorimetric dimensions (CIELAB) and additional dimensions to describe a metameric black (PQR). The spectral reproduction accuracies for printing on a six-color ink-jet printer were compared based on several versions of the ICS-based LUTs. Variations were evaluated with respect to quality trade-offs between size of the LUT and spectral reproduction accuracies, as well as the number of dimensions necessary for spectral color management. A five-dimensional 17x17x17x5x3 LUT performed well with three dimensions for CIELAB and two dimensions for the PQR metameric black space. This LUT resulted in average CIEDE2000 of 0.51 and average spectral RMS error of 4.22 % for a simulated spectral reproduction of the GretagMacbeth Color Checker.
