In aCMYK printing system, inputCMYK values are sampled uniformly between 0 and 255 to create 104 input–output characterization data set. The spectral data for each patch is measured at 31 wavelengths from 400 to 700 nm at 10 nm intervals. Use spectral PCA mathematical techniques to analyze the characterization data and fit a model. Using PCA vectors find parameters for a least squares and RLSmodel. Plot the model accuracy for test colors as a function of the number of basis vectors. Howmany basis vectors are needed to obtain a reasonably accurate model?
