Method for creating a color transform relating color reflectances produced under reference and target operating conditions and data structure incorporating the same

摘要

A printer is operated under a first set of conditions to create a first set of M number of samples and under a target set of conditions to create a second set of K samples. Each sample is produced using the same colorant(s). The actual spectral reflectance for each sample is measured. In accordance with the present invention the actual spectral reflectances for corresponding samples in the first and second sets are used to create a cross-validated, partial-least-squares transform that maps a reflectance from a sample produced under the first set of conditions to a reflectance from a sample produced under the target set of conditions.
