SPECTRAL PRINT MAPPING

摘要

A method for generating a print mapping and a method for image processing are described. The print mapping comprises obtaining spectral characteristics for printing fluids and determining reflectance values for computing a gamut in spectral space. The gamut provides a mapping of reflectance to Neugebauer Primary area coverages for a printing device.

1. A computer-implemented method for generating a print mapping, the method comprising:
obtaining spectral characteristics for at least a plurality of printing fluids; determining reflectance values for Neugebauer Primaries based on the obtained spectral characteristics; and computing a gamut in spectral space using the determined reflectance values, said gamut being modified according to print characteristics for a printing device; wherein the gamut is used to provide a mapping of reflectance to Neugebauer Primary area coverages for the printing device.
